Engineered for impressive performance, these PowerCrown staples feature a unique crown at the top of the staple that flattens 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 designed for use in the Bostitch EZ Squeeze 130 Stapler (B8130).
