Sealey 1/2" Drive Torx Socket Bit 1/2" T40

The Sealey T40 1/2" Drive Torx Socket Bit (Model SBT021) tackles larger Torx fasteners commonly found in heavy-duty automotive applications, including brake assemblies, steering components and chassis structural elements. This robust size is essential for commercial vehicle maintenance, 4x4 servicing and heavy mechanical work. Precision-forged from Chrome Vanadium steel with a hardened S2 steel bit insert, this socket delivers the strength required for high-torque applications without compromising dimensional accuracy. The heat treatment process ensures the bit profile remains precise even under extreme loading, preventing fastener damage and reducing the risk of cam-out. The fully polished chrome plating provides excellent corrosion resistance whilst creating a surface that's easily cleaned after exposure to workshop grime and road salt. The knurled ring design offers crucial grip enhancement, particularly when applying substantial torque to stubborn fasteners or working in positions
