Llave de vaso hexagonal Wera 05004558001 Zyklop 8790 HMC 1/2" con ranura de retención de bola, 18 mm

This 1/2-inch drive socket from Wera's Zyklop 8790 HMC series delivers a secure fit on 18 mm hexagonal fasteners. The 6-point profile grips the flats of the fastener rather than the corners, reducing the risk of rounding under high torque. A ball lock groove holds the socket firmly on the drive tool during use, while the knurled base provides a slip-resistant grip for finger tightening.

Advantages

The socket is made from chrome vanadium steel with a matt chrome-plated finish for corrosion resistance and durability. Wera's "Take it easy" colour coding makes size identification quick, even in a crowded tool box. The socket is suitable for manual and non-impact machine operation, complying with DIN 3124 and ISO 2725-1.

• Professional mechanics and technicians
