Sealey 1/4" Drive Deep Hexagon WallDrive Socket Metric

The Sealey 1/4" Drive 4mm Deep Hexagon WallDrive Socket is the smallest size in the range, ideal for precision work on delicate components and small-scale fasteners. This compact 4mm socket excels in electronics assembly, instrumentation work, and fine mechanical applications where larger tools simply won't fit. Cold-forged from Chrome Vanadium steel, this socket is hardened and tempered to deliver exceptional strength despite its diminutive size. The WallDrive® socket configuration grips fasteners on their flat sides rather than corners, providing superior torque transfer and reducing the risk of rounding off small, delicate fixings. The half chrome, half satin finish offers excellent corrosion resistance, whilst the knurled ring ensures positive grip control even when working in tight spaces with oily fingers. Perfect for automotive sensors, small engine components, and precision engineering tasks, this deep socket provides the extended reach needed for recessed applications. Backed by Sealey's lifetime guarantee, it's an essential addition to any comprehensive socket collection.
