Product Description Tube spanner wrenches by AVTODELO are used when working with fasteners, both in household conditions and in auto repair shops, service stations, and manufacturing. - Made by hot stamping (forging on hammers) from CrV steel. - Have a hexagonal profile of the working parts. - Equipped with 8 mm diameter holes for a ratchet. - Protected from corrosion by a chrome coating with a matte surface effect. Using a straight end wrench during car repairs ensures easy installation of threaded fasteners, even if the bolts or nuts are placed in deep areas where it is difficult to reach with a standard wrench.
