- Screws resist pulling out better, which suits pickets, rails and boards that swell and shrink with New York weather.
- Nails flex more under side loads and install faster, so ring-shank nails still make sense for posts-to-rail framing and large budget jobs.
- Match the fastener metal to the lumber: modern treated wood needs hot-dip galvanized or stainless, and coastal sites favor stainless.
- Use length about two and a half times the thickness of the board being fastened, and pilot holes in dense or cedar boards to prevent splits.
- Fence height, setbacks and permit rules vary by city, town and building, so confirm before you build.
Choose the wrong fastener and a fence can sag, rattle, split or bleed rust stains down new lumber within a couple of seasons. Choose the right one and the same boards stay tight for years. Nails and screws each have a role, and the question is not which is "superior" in general but which fits each connection in your fence. This guide compares them by strength, installation, corrosion, cost and repair, then covers sizes, local rules and the mistakes we see most.
1. The Short Answer
For most residential wood fences, use exterior-rated screws for pickets and boards, and use screws, bolts or ring-shank nails for the structural frame, all in hot-dip galvanized or stainless steel. Screws win on holding power and repairs. Nails win on speed, cost and the way they flex under side loads. A hybrid approach often gives the best result for the money.
If your fence is in a coastal area such as the south shore of Long Island or Staten Island's waterfront, upgrade the metal to stainless steel. Salt air attacks galvanized coatings faster than inland weather does.
The one rule that matters more than nails versus screws: never mix uncoated steel with treated lumber. The copper-based preservatives in modern pressure-treated wood corrode plain steel quickly, which is how fences end up with dark streaks and loose boards.
2. Strength: Tensile and Shear
Two kinds of load matter on a fence. Understanding them explains most fastener decisions.
Tensile strength: resisting pull-out
Tensile loads try to pull a fastener straight out of the wood. Wind pushing on a solid privacy fence pulls pickets away from rails. Wood also swells when wet and shrinks when dry, which works nails loose over time. Screw threads bite into the fibers and resist that motion. This is why screws are the better choice for pickets and boards.
Shear strength: resisting side loads
Shear loads push sideways across a fastener. A gate hanging from posts, or a rail resting on a post connection, applies shear. Screws are hardened and can be brittle; a heavily loaded cheap screw can snap, while a nail bends. Good structural screws and bolts are rated for shear, and nails have a long track record in framing, so the choice depends on the connection.
What the numbers mean in practice
Manufacturers publish allowable loads for their fasteners. Use those for structural connections, especially for gates and tall fences. For standard pickets, holding power is enough with common deck screws.
Wind and the New York factor
Open areas like Staten Island's south shore, the Rockaways or south-shore Long Island see strong wind. Solid privacy fences act like sails. Use more fasteners per board, solid posts set below the frost line and strong rail connections. Our fence installation advice for durable, low-maintenance privacy goes deeper on design.
3. Ease and Speed of Installation
Nails
A pneumatic nailer drives hundreds of nails quickly, and a framing hammer needs no pilot holes. For a long fence run on a budget, that speed matters. Nailers need an air compressor or battery and safe handling; the CDC's NIOSH publishes guidance on tool safety for workers. Mistakes happen quickly with a nailer, including splitting, overdriving and misfires.
Screws
An impact driver or drill sets screws accurately and controls depth. They take longer, and the cost of bits and batteries matters on big jobs. Pilot holes are wise in dense or dry cedar to prevent splitting near board ends. Self-tapping or star-drive screws reduce stripping.
The practical balance
A good pro crew, ours at N.Y. Renovation Services included, will often use nails for framing where speed matters and screws where holding power and repairability matter. A homeowner doing a small job usually does best with screws throughout, because forgiving, removable fasteners reduce the cost of mistakes.
4. Fastener Comparison at a Glance
| Factor | Nails | Screws |
|---|---|---|
| Pull-out resistance | Fair, better with ring or spiral shanks | Excellent |
| Side-load flexibility | Bends before breaking | Strong but can snap if cheap |
| Install speed | Fast with a nailer | Slower |
| Cost per fastener | Lower | Higher |
| Repairs and board replacement | Harder; pry bars damage wood | Easy; back them out |
| Adjustability | Poor | Good |
| Risk of splitting | Moderate to high without care | Lower with pilot holes |
| Best uses | Framing, rails, large budget runs | Pickets, boards, gates, repairable areas |
5. Corrosion, Coatings and Wood Type
Corrosion is the most common reason for fastener failure in the Northeast, and it is rarely about nails versus screws. It is about metal.
Match the metal to the lumber
- Pressure-treated lumber: Use hot-dip galvanized, stainless steel or fasteners specifically rated for treated wood. Electroplated "bright" nails and basic zinc-plated screws corrode quickly.
- Cedar and redwood: Natural tannins react with some metals and cause black streaks. Stainless steel is the best choice.
- Composite and vinyl fencing: Follow manufacturer instructions. Some systems use concealed clips; others require specific screws.
Coastal and humid locations
Salt air, standing moisture and fog increase rust. In Rockaway, Tottenville, Long Beach or Hoboken, stainless steel fasteners are worth the extra cost. In inland Newark or Hempstead, hot-dip galvanized is typically enough.
Look at the rating
Reliable packages state what lumber they suit and what coating they use. If a box does not say it is for treated lumber or exterior use, assume it is not.
Staining and painting
Fasteners with colored heads or coatings help blend into stained fences. If you plan to stain or paint, drive heads flush or slightly below the surface. Our guide to painting exterior surfaces and the exterior painting overview for NYC, Long Island and NJ cover the finishing process.
6. Sizes and Spacing
Sizes depend on what you are fastening. Treat the following as general rules and defer to manufacturer ratings.
| Connection | Typical approach |
|---|---|
| Pickets or boards to rails | Two fasteners per rail per board, 2 to 2.5 inch length for 1-inch boards |
| Rails to posts | Structural screws, carriage bolts or specified brackets |
| Gate frames | Through-bolts or structural screws with diagonal bracing |
| Post caps | Short screws or exterior construction adhesive plus fasteners |
| Horizontal slat fences | Screws with pilot holes to reduce splitting |
A few rules of thumb
- Penetrate the supporting member by roughly one and a half inches.
- Keep fasteners about three-quarters of an inch from board edges to reduce splitting.
- Avoid driving fasteners into end grain.
- Use ring-shank or spiral nails for better withdrawal resistance.
- Drive fasteners flush; do not overdrive and crush wood fibers.
Spacing for wind
In windy locations use more fasteners per board. Solid-board fences need two fasteners at each rail and sometimes three on wide boards.
7. Cost and Longevity
Fasteners are a small fraction of the total fence budget. The mistakes that cost money are cheap fasteners that corrode, boards that split and posts set in the wrong spot.
- Nails: Cheaper per piece and faster to install, so labor savings can be real on long runs.
- Screws: More expensive per piece, but they last as boards move and make repairs easier.
- Stainless steel: The highest material cost, with the longest life in coastal air.
Think about lifecycle cost. If you expect to replace boards or restain every few years, screws pay back by letting you replace one board without damaging its neighbors. If you want a rustic, low-cost fence that you will replace entirely in the future, nails are acceptable. We do not publish a flat per-foot fence price because soil, access, gates, slope and material change it dramatically. Our NYC renovation cost guide for 2026 covers how to think about budgets and itemized quotes.
8. Why a Licensed Pro Beats the Weekend Approach
A fence is a boundary, a structure and sometimes a legal issue. The fasteners are the small part.
Property lines and rules. Setbacks, height limits, corner-lot sight lines and shared fences can all create disputes. At N.Y. Renovation Services we check the survey, the zoning and the local rules before the first post goes in, and you can start with a free estimate. In a landmark district, a fence visible from the street can also need Landmarks review.
Posts and footings. Posts that are too shallow heave in frost and lean. Concrete mix, depth, spacing and drainage all matter. Utility marking is critical before digging.
Hardware choices. We choose fasteners by lumber type, exposure and connection, not by what was on sale. Bolts and structural screws go where the load is high; coated screws go where boards need to be replaceable.
Finish and protection. Our exterior team can stain or paint the fence as part of a coordinated exterior project, so boards are sealed before moisture can enter. N.Y. Renovation Services handles exterior painting across NYC, Long Island and New Jersey and can scope fence work alongside it.
Permits and paperwork. Where your project needs permits or board approval, our in-house design-and-build team handles the filing and the schedule. In NYC the Department of Buildings permit overview is the right starting place, and our Do I Need a Permit? page helps you decide when to ask.
Transparent pricing. Quotes are itemized in writing: posts, footings, rails, boards, hardware, finish, haul-away and permits. No hidden fees. N.Y. Renovation Services donates 5% of total project cost to a nonprofit chosen by the client.
9. Neighborhoods and ZIP Codes We Serve
Fence conditions and rules differ across our service area.
- Upper East Side, Manhattan (ZIPs 10021, 10028, 10065, 10075, 10128): pre-war co-ops, limestone townhouses and LPC districts. Rear-yard and terrace fences are common, and visible fence changes can require review. Building rules apply.
- Borough Park, Brooklyn (ZIPs 11219, 11204): large attached homes, multifamily buildings and high density. Shared property lines and narrow yards make exact survey work important.
- Corona, Queens (ZIPs 11368): attached homes, multifamily buildings and basements. Fence lines often run along narrow driveways and shared walls.
- Bulls Head, Staten Island (ZIPs 10314): detached homes and townhouse communities. Larger lots invite longer fence runs, and townhouse communities may have HOA rules.
- Hempstead, Nassau County, Long Island (ZIPs 11550): capes, colonials and multifamily housing in the Town and Village of Hempstead. Check the town building department and see the Nassau County website for local contacts.
- Newark, Essex County, NJ (ZIPs 07102, 07103, 07104, 07105, 07106, 07107, 07108): Ironbound row houses, historic districts, multifamily housing and condos. Municipal rules apply, and the New Jersey DCA Codes and Standards site explains the state Uniform Construction Code.
If you own a townhouse in the Upper East Side, our Upper East Side historic restoration page shows the type of work we do in landmark areas.
10. Common Fence Fastener Mistakes
- Using interior drywall screws. They snap and rust.
- Using uncoated steel with treated lumber. Corrosion and streaks follow.
- Overdriving. It crushes fibers and reduces holding power.
- No pilot holes near board ends. Splits are almost guaranteed in dry cedar.
- Fastening only at the top. Boards cup and twist.
- Under-fastening in windy areas. Boards rattle and loosen.
- Skipping the sealed cut ends. Moisture enters at cut ends.
- Choosing nails for gates. Gates carry heavy shear and need bolts or structural screws.
- Ignoring the survey. A fence on the wrong side of a line is expensive to move.
- Forgetting utility marking. Digging without it can be dangerous and illegal.
A simple build sequence: confirm lines and rules, mark utilities, set posts, let concrete cure, hang rails with structural fasteners, attach pickets with screws or ring-shank nails, seal cut ends, then stain or paint. Skipping the cure time or the sealing is where many fences start failing.
