When you are reaching for a 5/16 inch socket, you want something that fits right and lasts. This Wera Zyklop 1/4 inch drive socket, model 8790 HMA, is built from chrome vanadium with a brushed chrome finish that stands up to workshop abuse. It is specifically designed for hex bolts and nuts, featuring a knurled base that allows for easy manual turning when you are starting a thread. The color-coded ring makes it easy to spot in a crowded tray, and the ball intercept ring ensures it stays put on your ratchet or extension.
