Tuhls 1/2" Drive Long (4") M12 Triple Square Socket

Tuhls 1/2" Drive M12 Triple Square Socket, 4" Long

The Tuhls 1/2" Drive M12 Triple Square Socket in the extended 4" length is built for the triple square fasteners you cannot reach with a standard socket. The long body drops down into recessed bores and past surrounding hardware to seat fully on the bolt, so you get proper engagement without stacking on extensions that rob you of feel and control.

M12 triple square hardware shows up on some of the most demanding work on a European vehicle, including axle and hub bolts, driveshaft and flex disc hardware, cylinder head bolts, subframe and suspension mounting hardware, and brake components. The 1/2" square drive pairs with full size ratchets, breaker bars, and torque wrenches, giving you the leverage and torque capacity those fasteners demand.

Extended 4" Reach

The added length is the whole point. Deep counterbores, control arm pockets, and fasteners set behind brackets or heat shields put a standard socket at the wrong depth, where it engages only partially and starts to round the bolt. The 4" body reaches the fastener directly and stays square to it, which keeps torque flowing into the bolt instead of into a stack of adapters.

Professional-Grade Construction

Built for strength and wear resistance, this socket features precision-machined M-profile geometry that engages the fastener across its full flank surface. That accurate fit reduces the risk of rounding or slipping when a stubborn bolt is fighting back, and it keeps the socket serviceable job after job.

Designed for European Applications

Triple square hardware is standard equipment across the modern European fleet, and using the correct M-profile tool is the difference between a clean removal and a damaged fastener. Whether the work is happening on a shop lift or a driveway jack stand, this long reach socket delivers dependable performance on Volkswagen, Audi, BMW, Mercedes-Benz, Porsche, and other German platforms.
