Size: 18 Pack Product Description: Legendary Bostitch B8 PowerCrown staples are crafted for ultimate drive performance. Taking the physical dynamics of staple driving into consideration led our engineers to develop the unique PowerCrown feature. As this crowned (peaked) staple top is flattened during the staple drive, it forces the staple legs outward so they are more fully supported by the stapler magazine throughout the drive. This delivers more stapling force and reduced buckling for maximum penetration. Each full strip contains 210 staples and is constructed from superior quality high carbon wire to reduce buckling and jamming. The finely honed chisel points deliver maximum penetration for maximum sheet capacity. ¼" leg length. 5,000 staple quantity per box.
