The Bostitch SB355/8-5M heavy-duty staples are engineered for deep, secure fastening in thick documents, heavy paper bundles, catalogs, manuals, and packaging tasks. With a 5/8" leg length, these staples deliver strong penetration and a tight clinch, making them ideal for large-volume stapling or jobs where standard or medium-duty staples would fail.
Built from high-carbon steel, the SB355/8-5M staples resist bending, buckling, and jamming — even under heavy load. Precision-cut chisel points ensure smooth entry through dense stacks of paper, cardboard, or lightweight materials. A large 5,000-count pack provides excellent value and long-term supply for mailrooms, print shops, offices, and production environments.
