The Sealey 8 Piece 1/4" and 3/8" Drive Lock On Hexagon Socket Bit Set Imperial is a professional socket set designed for removing damaged and rounded fasteners. Featuring heat-treated Chrome Vanadium steel sockets paired with S2 steel hex bits, this imperial set provides a robust solution for challenging fastener situations across automotive and maintenance applications. The patented twist design delivers a unique gripping mechanism that tightens as the socket turns, making it particularly effective on rusted, damaged or severely rounded hex head fasteners. This innovative design helps prevent further fastener damage during removal, whilst the zinc phosphate finish on the hex bits provides corrosion resistance and extended service life.
