Sealey 1/4" Drive Hexagon WallDrive Socket Metric 1/4" 5.5mm

The Sealey 1/4" Drive 5.5mm Hexagon WallDrive Socket fills an important gap in metric sizing, providing the precise fit required for less common fastener dimensions. This 5.5mm socket proves particularly valuable when working with specialist equipment, imported machinery or precision assemblies where standard sizes don't quite fit properly. Cold-forged from premium Chrome Vanadium steel and subjected to hardening and tempering processes, this socket delivers professional-grade strength and longevity. The innovative WallDrive® configuration is especially beneficial with this intermediate size, as it grips fasteners on their flat sides rather than corners, ensuring you can apply proper torque without the risk of rounding fasteners that might be difficult to replace. The chrome-plated finish with fully polished mirror surface provides excellent corrosion resistance and easy cleaning, whilst the knurled ring ensures secure grip even with oily fingers.
