696800-KM4 - Locknut Socket The Sykes-Pickavant KM Sockets are designed for the safe, accurate installation and removal of KM locknuts - specialised precision nuts used to secure bearings and other critical components on shafts. These nuts feature slots around their circumference, which means a standard socket or spanner cannot be used without risking damage to the nut or shaft. KM sockets are purpose-built tools that engage directly with the nut’s slots, providing a positive drive connection that distributes torque evenly. This prevents slippage, rounding, or distortion - common issues when improvised tools are used - and helps maintain the integrity of both the locknut and the component it secures. The socket demands less space around the bearing arrangement than when using a hook spanner and allows the use of ratchets and torque wrenches via a 1/2" drive.
