N Series Staples Defined — The 16 Gauge Medium Crown Standard for Pneumatic Fastening

N Staples are professional fine wire fasteners with narrow crowns. They are commonly used for precision finishing and light duty fastening jobs. It focuses on delicate fixation scenarios, requiring precise surface finishing without damaging the material, and is standardized with 22GA thin wire and 10mm narrow crown structure. Its light-weight structure is suitable for low load fastener requirements in the furniture decoration, craft production and interior renovation industries.

Sinsun and Staples' core competitive advantage is ultra-high consistency and batch precision. During the production process, we adopt micron-level dimensional tolerance control and multi-layer surface polishing treatment. The optimized narrow crown stress dispersion structure can be tightly fixed and has a small trace on the surface of the material.

N Series Staples Defined — The 16 Gauge Medium Crown Standard for Pneumatic Fastening

Sinsun N Series Staples by Leg Length — Complete 16 Gauge Range from 16mm to 50mm

Browse our full N series staple lineup organized by application. Each variant features 16 gauge wire, 7/16” medium crown, and adhesive collation for jam‑free pneumatic driving. Leg lengths from N16 (16mm) up to N50 (50mm).

N16 Staples

N16 (16mm / 5/8″)  Staples

Shorter leg length for precision woodworking. Ideal for assembling drawer boxes, attaching cabinet backs to carcasses, and securing 6mm‑9mm plywood panels where a longer staple would blow through the opposite side. The 16mm leg provides enough bite for stable joinery without visible fastener heads on finished surfaces. Cabinet shops and furniture manufacturers frequently order N16 as their daily‑use standard for light‑to‑medium wood assembly.

N19‑N22 Staples

N19‑N22 (19‑22mm / 3/4″‑7/8″) Staples

Medium leg length for finishing work and outdoor use. N19 staples are used for attaching cedar lattice panels to wood frames, attaching decorative trim to fascia boards, or attaching soffit material to roofline framing. Because of our galvanized coating, the 16 gauge wire has sufficient corrosion resistance to make these N series staples a good choice for covered outdoor work where exposure to full weather is limited.

N25‑N28 (25‑28mm / 1″‑1‑1/8″)Staples

N25‑N28 (25‑28mm / 1″‑1‑1/8″)Staples

The range most used by the construction crew. The 25mm leg passes through the wall sheathing of 7/16″ OSB and locks into the 2×4 wood stud, while the 7/16″ medium crown spreads holding force over the surface of the panel to resist wind uplift. N28 staples are perfect for subflooring projects where 18-22mm plywood or OSB panels are fastened to floor joists, as they give the extra 2-3mm of purchase needed for a secure clinch on the blind side.

N30‑N35 (30‑35mm / 1‑3/16″‑1‑3/8″) Staples

N30‑N35 (30‑35mm / 1‑3/16″‑1‑3/8″) Staples

The extra leg lengths are essential for packaging lines and pallet shops. Drive 12-15mm hardwood deck boards into 25mm stringers. The staple should go through both layers and have enough bite left to clinch flat inside the stringer wood. The 7/16″ crown keeps the fastener from pulling through the deck board when the pallet is exposed to forklift loading or freight handling. Crate assemblers who also export use N30-N35 staples to join pine or spruce frame members where nails would split the grain.

N38‑N45 (38‑45mm / 1‑1/2″‑1‑3/4″) Staples

N38‑N45 (38‑45mm / 1‑1/2″‑1‑3/4″)  Staples

Longer legs for outdoor structural and structural framing.The strongest posts must be braced with 2x4s, fence rails should be nailed to 4x4 posts, and deck boards should be screwed to the joists with 19-22mm deck screws.The 16 gauge wire generates the power to drive through pressure treated lumber without bending the crown, which is a common failure point for cheaper N series staples that have inconsistent heat treatment.
Send inquiry Now
N50 (50mm / 2″) Staples

N50 (50mm / 2″) Staples

The longest leg of the N series family. Designed for building up thick wooden containers or for fastening together double layers of 18mm plywood on 25mm framing members or for fastening 2x lumber to concrete forms where penetration depth is important to holding power.N50 fasteners provide the holding power contractors need without using heavy gauge fasteners for engineered wood products or multiple laminates.

Where N Series Staples Deliver — Sheathing,
Pallets, Furniture & More

Wall sheathing attachment, wooden pallet assembly, furniture frame construction, subfloor fastening, fence rail installation, and export crate sealing. Six specific scenarios where Sinsun N series staples provide faster cycles, fewer jams, and stronger holds.

Building Construction & Wall Insulation Fastening

The N28 staple (28mm leg) is used by flooring contractors to secure 18-22mm plywood or OSB subfloor panels to wooden floor joists. This length goes through the thickness of the subfloor and into the joist by 6‑10mm, giving the pull‑out resistance needed to prevent floor squeaks for decades of foot traffic. The 7/16″ medium crown lies flush with the subfloor surface, so finished flooring materials can lay flat without being hindered by fastener heads.

Mark Wilson | Country: USA

We have purchased galvanized N series upholstery staples repeatedly. These heavy-duty N staples fit our N851 staple gun perfectly with zero jamming. The galvanized coating delivers reliable anti-rust performance when fixing solid wood sofa frames, and the wire hardness stays consistent without bending when driving into hardwood. We will keep placing bulk orders long-term.

Liam Carter | Country: Australia

I tried 304 stainless steel N staples for outdoor wooden deck projects. Compared with other suppliers, these N staples have neat glue collation and stable quality. The wide crown design holds wood panels tightly, and there is no corrosion after exposure to humid coastal weather. Highly recommend these furniture staples for outdoor construction jobs.
