Sealey 1/4" Drive Hexagon WallDrive Socket Metric

The Sealey 1/4" Drive 4mm Hexagon WallDrive Socket is the smallest size in this professional metric range, perfectly suited for precision work on delicate fasteners and compact assemblies. This 4mm socket proves invaluable when working on small engines, electronics housings, intricate machinery or any application where space is at a premium and fastener sizes are correspondingly small. Cold-forged from Chrome Vanadium steel and hardened for exceptional durability, this compact socket features the innovative WallDrive® configuration that grips fasteners on their flat sides rather than corners, reducing rounding risk even on smaller, more delicate fasteners. The chrome-plated finish with fully polished surface provides excellent corrosion resistance, whilst the knurled ring ensures you maintain control even with oily fingers during intricate work. The 1/4" drive fitting makes this socket compatible with fine ratchets and torque wrenches, delivering the precision control essential for smaller fastener work. Backed by Sealey's lifetime guarantee, this 4mm socket is an essential addition to any comprehensive tool kit.
