Legendary Bostitch B8® PowerCrown™ Staples are crafted for ultimate drive performance. The unique PowerCrown design takes the physical dynamics of staple driving into consideration. Each of these 1/4″ staples is crowned or peaked at the top. As the staple is flattened during the staple drive, the crown design forces the staple legs outward so they are fully supported by the stapler magazine throughout the drive. This design helps deliver more stapling force and reduces buckling for maximum penetration. Because of this, PowerCrown staples are considered some of the best in the industry. Each full strip of Bostitch B8 staples contains 210 staples. They are constructed from superior quality high carbon wire to reduce buckling and jamming. The finely honed chisel points deliver ideal penetration for the greatest sheet capacity. Each features a ¼” leg length. There are 5,000 staples per box.
