The SB50195/8-4M plier staples from Bostitch are heavy-duty staples built for industrial carton-closing, corrugated container sealing, pallet-box assembly, and high-volume packaging operations. With a 5/8" leg length and a 1/2" crown, these staples are designed for deep penetration through thick cardboard, layered corrugated boards, and crate-style packaging — ensuring secure clinch and reliable hold even under demanding use.
Manufactured from flat galvanized heavy-gauge wire (approx. .050" × .019"), these staples deliver strength, durability, and corrosion resistance for long-term performance in industrial environments. The galvanized finish helps withstand wear from repeated use, while the sturdy wire gauge resists bending or misfires. Supplied in packs of 4,000 staples, they offer a cost-effective, high-capacity solution for warehouse, shipping, and packaging operations.
