3/8"SD 5 Sided Tamperproof Torx Plus / TS Bit Socket Set Britool Hallmark M2BTSSET10

This Britool Hallmark 3/8" square drive Torx Plus (TS) bit socket set is engineered for professional automotive and workshop use, combining precision machining with outstanding durability. Each socket features a fixed premium S2 steel bit, delivering excellent strength, wear resistance, and precise engagement under repeated use.

Designed with a 5-sided star Torx Plus profile and a central security hole, these bit sockets are ideal for tamper-resistant fasteners commonly found on modern European vehicles. They are widely specified for Renault, PSA, and Mercedes-Benz applications, particularly within air conditioning systems, fuel injection pumps, engine control units, automatic gearboxes, and clutch assemblies where secure fastening is critical.

The fixed socket construction ensures consistent torque transfer and minimises the risk of slippage, making this set an essential addition for technicians working on modern vehicle electronics and driveline components. Finished with Britool Hallmark quality and supplied neatly organised in a tool control foam tray, the set fits directly into a toolbox drawer for efficient storage and fast tool identification. Individual bit sockets are also available separately should replacements be required.

The set includes sizes TS8, TS10, TS15, TS20, TS25, TS27, TS30, TS40, TS45, and TS50, each with an overall length of 48mm.
