Premium PowerCrown staples are crafted for ultimate drive performance for use in the Bostitch B8E, B8E-VALUE, B8HC, B8HDP, and 02245. 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. Finely honed chisel points deliver maximum penetration for maximum sheet capacity. Staples with 3/8" leg length fastens up to 45 sheets of paper, light corrugate, fiber board, plastic and other light packaging materials.
