05003389001 Zyklop 1/4" Hex socket bit w/ holding function US sizes

Designed for 5/16-inch hex fasteners, this Wera Zyklop 1/4-inch drive socket bit is a heavy-duty solution for your workshop. It utilizes the 8740 A HF profile, which incorporates a holding function to keep the bolt secured to the bit. This is especially helpful when working on Harley-Davidson models where space is at a premium. The Hex-Plus bit design offers a larger contact area to prevent bolt head deformation, ensuring your hardware stays in top condition. Constructed from chrome vanadium with a brushed chrome finish, it features a knurled base for manual control and a ball intercept ring. This 28mm bit is color-coded for quick selection but should not be used with impact wrenches.
