Proto, J7421MT, Impact Socket, 1/2 in Drive; 21 mm, 12 Point, TorquePlus Design

Crafted for efficiency and performance, this impact socket from Proto features a 21 mm size and a 12-point configuration designed to handle even the most stubborn or damaged fasteners. The innovative TorquePlus design significantly reduces slippage by employing a radius-corner approach, shifting stress away from fastener corners and effectively distributing it across a larger area, which not only enhances socket engagement but also minimizes the risk of rounding off fasteners. This socket is specifically ideal for use with softer materials and provides the added advantage of a side locking hole for secure attachment. Stamped with its size for easy identification, this tool meets the demands of both professionals and DIY enthusiasts looking for reliability and durability in their fastening jobs.
