Engineered for impressive performance, these Legendary Bostitch PowerCrown staples feature a unique crown (peak) at the top of the staple that flattens when driven down during stapling. Forced outward, the legs are better supported by the stapler magazine throughout the drive, resulting in more stapling force and reduced staple buckling. Staples are made from superior-quality, high carbon steel wire with finely sharpened chisel points for maximum sheet capacity. They are optimized for the Bostitch EZ Squeeze 130 Stapler (B8130).
