Sinsun 71 Series Staples are standard 22 gauge fine wire U-shaped staples. They feature a 9mm narrow crown and chisel-point design. This series of industrial staples for mainstream use is manufactured in unified dimensions. It perfectly matches mainstream staple guns such as BeA 71, Senco C and Prebena V models. This design of fine wire staples allows for ultra-clean penetration without tearing thin materials or leaving visible indentations on the product surfaces, as occurs with regular thick wire staples.
Sinsun is a professional fastener manufacturer, with decades of production experience. Sinsun optimizes the internal metal structure of 71 Series Staples by precision cold forging and high temperature tempering treatment. The finished staples have the same hardness and toughness, effectively avoiding common industry problems such as brittle fracture, bent legs and uneven nailing. All product batches are strictly dimensionally calibrated to ensure consistent tolerance. This greatly improves automatic nailing success rates and reduces production downtime.

Practical Application Scenarios of Sinsun 71 Series Staples
Discover multi-scenario applications of Sinsun 71 Series Staples, covering furniture upholstery, automotive interiors, mattress manufacturing and light industrial fastening.
Sofa & Chair Upholstery Production
Furniture factories drive millions of 71 series staples into foam padding and plywood frames every year.When used on microfibers or leathers with a narrow crown (9.10mm), entry marks are virtually invisible.Our staples 71/10 can be used for fabric over foam. If the padding is thicker than 15mm, use 71/12 instead. Our chisel points track straighter through material than cheap generic staples, resulting in 40% fewer line stoppages.
Mattress Edge Banding & Pocket Spring Assembly
Bedding manufacturers staple fabric tape at rates of up to 100 staples a minute along the edges of mattresses. 6mm leg length penetrates ticking fabric and insulation felt without protruding to the sleeping surface. Our 304 stainless option prevents corrosion from sweat and moisture over the mattress life span (8-12 years). We offer in bulk packaging of 20,000 per box.
Automotive Headliners, Door Panels & Carpet
71 series staples are used by vehicle interior suppliers to attach headliner fabric to fibreglass backer boards, low crown profile prevents visible impressions. Door panel fabric wraps use 71/8” (8mm) staples into a plastic or wood fibre substrate. Our Sinsun 71/10 and 71/12 options are popular in the aftermarket upholstery shops in Europe and the Middle East.
Cabinet Backing & Light Wood Assembly
Cabinet makers use 71 series staples to staple thin plywood back panels to carcasses. The thin gauge (22) won’t split 3mm or 4mm plywood edges, unlike larger 18-gauge brad nails. 71/10 leg length goes through the decorative skin and into the solid wood frame to secure drawer bottoms.
Packaging: Corrugated Carton Sealing
Pneumatic carton staplers in fulfilment centers use 71 series staples. 9mm crown and 10-12mm leg length will bite through double-wall cardboard without punching through the other side. Staple cartons do not lift in humid storage, unlike tape. Sinsun’s galvanised coating prevents rust streaking on white shipping cartons.
Sinsun vs. Resellers – We Are The Factory
Most 71 series staple suppliers are trading firms. Sinsun has its own wire drawing, staple forming, heat treating and coating lines.
This implies
- *Crown variance: No than ±0.10mm (according to our drawing). Smoother feeding, less jamming.
- *Less price: No middleman markup. B2B ordering runs from 50,000 pieces to full containers, factory direct pricing.
- *Custom runs faster. Need a non‐standard leg length, such as 71/9, or a particular colour? We repair in days, not weeks.
Installation Guide (30 sec Quick Reference)
*Check what you need: Your stapler should say “Type 71 / 71 series staples”.
*Choose leg length: Use our selection matrix (section 4).
*Load Magazine: Insert a staple strip with legs facing the drive direction.
*Air pressure (pneumatic): 4-5 bars (60-70 psi) to begin with. Adjust if staples do not seat properly. Do not exceed 8 bars (115 psi).
*Test firing into scrap material of similar thickness.
