LOK-ON Unlock locked fasteners with LOK-ON sockets! The LOK-ON range of Sockets and Accessories is an ideal companion for removing rounded fasteners. Kincrome ‘LOK-ON’ sockets drive the side of the fastener using a unique subtle cam found in the 6 point socket design. This unique design not only provides increased strength and better torque, LOK-ON also avoids the rounding of rusted and damaged fasteners. The cam design also enables the user to effectively loosen fasteners which have rounded by up to 85%. The ‘LOK-ON’ design helps reduce stress concentration when torqued, preventing the fastener from rounding whilst offering better torque than conventional sockets.
