Standard Nutsetters feature a small internal chamfer to facilitate quick screw engagement. The chamfer also reduces marking of the head—shoulder junction when using painted hex head screws.
 All Bordo Nutsetters are manufactured from premium heat treated alloy steel and feature powerful magnets. The universal 1/4" hex shank is suitable for use in most power tools and quick change adaptors/extensions.   Supabit Extreme Impact Bits – Certified ‘heavy hitters’ specifically developed for use with the high-torque output of an impact driver.
