The sealey 5 piece 1 2 drive double ended alloy wheel impact socket set is a specialist socket set designed to tackle swollen and corroded wheel nuts on alloy wheels. This professional grade tool addresses a common challenge faced by mechanics and technicians when chromium plated caps on wheel nuts expand, making them incompatible with standard whole size sockets. Manufactured from chrome molybdenum steel, these impact sockets are heat treated and anodised for exceptional durability and corrosion resistance. The half size configuration ensures secure fitment on swollen nuts, enabling safe removal without damaging the fixings or surrounding wheel components. Each double ended 6 point socket features a thin walled design suitable for use with impact wrenches and air tools, whilst the external sleeve prevents damage to delicate alloy wheel surfaces and nuts. This set is ideal for automotive workshops, tyre fitting centres, and mobile mechanics who regularly work on alloy wheeled vehicles. The range of half sizes covers the most commonly encountered swollen wheel nut dimensions, making it an essential addition to any professional tool collection where wheel removal and refitment is routine work.
