Wera 8790 HMB HF Zyklop 3/8in. Drive Sockets - Metric

<P>These 3/8 inch drive Zyklop sockets from Wera have a holding function that retains hexagonal headed bolts or screws in the socket for extremely convenient driving, with reduced risk of losing the bolt or screw when addressing the workpiece.</P><P>The clamping of the screw is achieved by a twin spring-loaded ball system and is especially helpful in confined, hard-to-reach spaces, where there is no room for a second hand to hold the bolt in the socket.</P>
