Heavy-duty staples are designed to deliver premium stapling performance. Superior-quality, high carbon steel wire reduces staple buckling and jamming. The finely chiseled points pierce stacks of paper for maximum sheet penetration. Staples are compatible with most heavy-duty staplers, including Bostitch Antimicrobial 215-Sheet Extra Heavy-duty Staplers (00540) and Antimicrobial 130-Sheet Heavy-duty Staplers (B310HDS). The 5/8" (15mm) leg length staples 85 to 130 sheets. More from the Manufacturer
