IVY Classic Nut Setters are designed to withstand the high torque (rotational force) of impact drivers. Made from high-quality Chrome Vanadium Steel for extra strength and durability, these nut setters feature a lobular design to reduce the stripping of the corners of the nut, ensuring that fasteners are driven on their flat sides instead of their corners. IVY Classic nut setters are designed with an extra strength magnet secured in place with a splined brass bushing resulting in greater retention of your fastener. IVY Classic Industries manufactures an extensive line of 1- 5/8” through 6” nut setters in a variety of sizes and lengths. IVY Classic Industries is dedicated to producing a comprehensive, quality line of power tool accessories and hand tools.
