EZ Squeeze Premium Staples are made with Bostitch's B8 PowerCrown feature for ultimate drive performance. As this crowned (peaked) staple top is flattened during the staple drive, it forces the staple legs outward so they are more fully supported by the stapler magazine throughout the drive. This design delivers more stapling force and reduced buckling for maximum penetration. Staples are constructed from superior-quality high-carbon steel wire to reduce buckling for maximum penetration. The EZ Squeeze staples are crafted for specific optimum performance in Bostitch's reduced effort, heavy-duty stapler, EZ Squeeze 130. Finely honed chisel points deliver maximum penetration. Each staple fastens up to 130 sheets. Leg length is 5/8". Staples come 100 per strip.
