Stanley SharpShooter TRA700 series narrow crown staples deliver dependable holding power for heavy-duty stapling. Each 9/16" leg staple is made from 24-gauge galvanized steel wire with a 27/64" narrow crown and a chisel point that drives cleanly into wood, insulation board, and most fabric-over-wood assemblies. The 1,000-staple pack with color-coded packaging makes it easy to grab the right size at the jobsite.

• Also fits Arrow T-50 and other T-50-pattern staple guns
• 1,000 staples per pack

Selection Tip: 9/16" leg is the maximum capacity of the TRA700 staple line - heavy carpet pad, thick batt insulation, multi-layer house wrap, and stacks where shorter staples won't fully bridge through to solid wood. Manual guns may struggle at this length - a TRE500-class electric or hammer tacker delivers more consistent set. Match staple leg length to the combined thickness of the material being attached plus 1/8" to 1/4" of penetration into the substrate. A leg that bottoms out hard against the staple gun usually means the leg is too short for the stack; a leg that won't seat flush usually means it is too long for the substrate or the air pressure / hammer force is too low.

Use Tip: Hold the gun perpendicular to the surface and squeeze the trigger fully in one motion. Two-handed grip on heavy-duty manual guns keeps the staple square and prevents skipped fires. For overhead work (ceiling insulation, house wrap), use the hammer tacker variants rather than a manual squeeze gun to reduce fatigue.

Note: Galvanized staples are intended for interior or protected exterior use. For prolonged outdoor exposure or wet environments (siding underlayment, exterior trim), step up to stainless steel staples to prevent corrosion bleed-through on finished surfaces. Wear safety glasses - staples can deflect off knots or hard substrates.
