Steel: CrV50Bv30 45—47 HRC Chroming D1: 14 mm D2: 22 mm Length: 38 mm "Delo Techniki" socket wrenches are made of chrome-vanadium steel using cold stamping and subsequent heat treatment. The wrenches are hardened and protected from corrosion by chroming. They can withstand high and prolonged loads. Torx - a six-pointed profile in which the direction of force is distributed perpendicular to the surface of the contact points, which quickly increases their area as the load increases and practically eliminates damage to the edges. The special rifled texture on the base of the wrench improves grip characteristics and prevents slipping in the hands. You can also purchase a set of TORX socket wrenches.
