Staples are U‑shaped fasteners designed for quick, clean, and reliable attachment across jobs ranging from upholstery and cabinetry to roofing felt, house wrap, and packaging. Used with manual, electric, or pneumatic staple guns and hammer tackers, they deliver speed, a low-profile finish, and strong holding power with minimal surface damage compared to many nails or screws.

Choose the right staple by matching four key specs:
- Crown width: narrow crown (finish work, trim, casing), medium crown (underlayment, sheathing), wide crown (insulation, house wrap, felt).
- Wire gauge: fine wire 20–22 ga for fabrics and delicate materials, 18 ga narrow crown for carpentry and general construction, heavier gauges for demanding fastening.
- Leg length: select a length that penetrates the top material and anchors firmly into the base. A common rule is to drive 2–3× the thickness of the top material into the substrate. Use shorter legs for upholstery and softwoods; longer legs for hardwoods and thick stacks.
- Material/coating: galvanized staples suit most indoor/outdoor framing tasks; stainless steel resists rust in exterior, coastal, and high‑moisture environments. Resin- or glue‑coated options increase holding power; divergent point tips improve grip in sheathing and subfloors.

Common types include T50 staples for general purpose and hammer tackers, upholstery staples for fabrics, narrow crown construction staples for trim and light framing, wide crown staples for insulation and wrap, cable staples with insulated saddles for low‑voltage runs, and fence staples (U‑nails) for wire and mesh.

For best results, verify the staple series your stapler accepts (e.g., T50, 18GA narrow crown). Check strip length and quantity for fewer reloads on production runs, and store staples dry to prevent corrosion. Always wear eye protection.

Whether you need heavy‑duty construction staples or fine wire upholstery staples, the right combination of crown, gauge, leg length, and finish will speed up work, improve holding strength, and deliver cleaner results on wood, fabric, plastics, and composites.
