Product Description: Legendary Bostitch B8 PowerCrown Staples are manufactured for ultimate drive performance. Taking into account the physical dynamics of driving staples, our engineers developed the unique PowerCrown feature. Since this crowned (chopped) stapling top is flattened during the stapling unit, it forces the stapling legs outward so they are more fully supported by the stapling magazine throughout the unit. This provides more stapling force and reduced buckle for maximum penetration. Each full strip contains 210 staples and is made from high quality carbon wire to reduce buckling and jamming. Finely honed chisel points offer maximum penetration for maximum blade capability. Leg Length: 1" Quantity of 5,000 staples per box. Set includes 2 boxes. 10,000 staples in total. The manufacturer's PowerCrown B8 staples are built for ultimate drive performance and designed for use in Bostitch B8E, B8E-Value, B8HC, B8HDP, B8R, B8P (02245), B8RC-FC, B8RC-2G, B8RC and B8RCB. Since this crowned (chopped) stapling top is flattened during the stapling unit, it forces the stapling legs outward so they are more fully supported by the stapling magazine throughout the unit. This provides more stapling force and reduced buckle for maximum penetration. Staples are made from superior quality carbon wire to reduce buckling and jamming. Finely ground chisel points offer maximum penetration for maximum blade capacity with a 1/4" shank length.
