Engineered for impressive performance. Legendary Bostitch PowerCrown staples have a unique crown (peak) at the top of the staple that flattens when driven down during stapling. Forced outward, the legs are better supported resulting in more stapling force & reduced buckling. Made from superior quality high carbon steel wire with finely chiseled points for maximum sheet capacity. Staple Collation: Half-Strip; Staples per Strip / Cartridge: 105; Sheet Capacity: 75; Leg Length: 0.38".
