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 and 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: 130; Leg Length: 0.5".
