Sealey 1/4" Drive Polished Deep Hexagon WallDrive Socket Metric

The Sealey 1/4" Drive 4mm Deep Hexagon WallDrive Socket is the smallest size in this professional metric range, ideal for precision work on delicate fasteners and confined spaces where compact components are used. This socket size is particularly valuable for automotive electronics, instrumentation panels and small engine assemblies where 4mm fixings are commonly specified. Manufactured from cold-forged Chrome Vanadium steel, this socket is hardened and tempered to deliver reliable strength despite its compact dimensions. The chrome plated finish with full polish provides excellent corrosion resistance whilst making it easy to identify in your socket collection. The WallDrive® configuration grips fasteners on their walls rather than corners, minimising the risk of rounding even on smaller bolt heads, whilst the deep hexagon profile accommodates longer threaded studs. A knurled ring ensures you maintain positive control even when working with oily fingers, and the socket is backed by Sealey's lifetime guarantee.
