Sealey 1/2" Drive Impact Socket Metric for Alloy Wheels

At the larger end of the range, this 27mm 1/2" drive impact socket covers specialist applications including certain commercial vehicles, vans and specific premium car models with larger wheel fixings. The combination of substantial sizing and protective features makes it essential for workshops handling diverse vehicle fleets or specialist vehicles with non-standard wheel nut specifications. Constructed from Chrome Molybdenum steel and precision hardened and tempered, this socket is engineered to handle the significant torque demands of larger wheel fixings whilst withstanding repeated impact tool operation. The comprehensive double-sleeving system – covering both external surfaces and internal walls – provides crucial protection for alloy wheels and nuts, preventing the scratches and cosmetic damage that can occur with standard impact sockets. The 6-point design maximises contact with fastener flats, reducing stress concentration and the risk of rounding off even when dealing with corroded or seized fixings. Colour-coding enables instant identification amongst your socket collection, whilst the anodised finish delivers excellent long-term corrosion resistance in demanding workshop environments.
