Overview
Whittet-Higgins TLM-06 Locknut
The Whittet-Higgins TANGENTLOK TLM series is a metric, mechanically self-locking shaft locknut with a base threaded nut in carbon steel and hardened alloy fasteners. Three hex socket-head cap screws are seated tangentially (X-axis) around the outside diameter; torquing them in a bolt-circle pattern deforms the relieved inner section of the nut to deliver uniform 360-degree thread clamping to the center of the shaft.
This self-locking action prevents assemblies from loosening due to vibration, shock and torque without damaging the shaft threads or requiring a cut keyway, while providing infinite adjustment and preloading. The balanced design suits high-speed assemblies, installs faster than a traditional locknut and lockwasher, and the series meets and exceeds ISO 2982-2:2013(E) with a maximum operating temperature of 300 degrees F. Manufactured in the USA and RoHS compliant.

About the brand
About Whittet-Higgins
Bearing locknuts, lockwashers and retaining devices from Rhode Island since 1914.
Henry Whittet and John Higgins founded the Whittet-Higgins Manufacturing Company in 1914 in the basement of a mill on Congress Avenue in Providence, Rhode Island, making super-precision bearing retaining components and machined parts for local machine builders such as Brown & Sharpe.
In 1967 the company was sold to a young mechanical engineer, and in 1969 it moved to 33 Higginson Avenue in Central Falls, Rhode Island, where it still makes its products. Its first line of 66 locknuts and lockwashers has grown to more than 4,300 standard parts, made on robotic CNC systems.
Besides the standard N/AN and KM locknuts with W and MB lockwashers, Whittet-Higgins makes its own self-locking designs: Bearhug prevailing-torque locknuts, Bearlok, Shoelok and Tangentlok clamping locknuts, clampnuts and splitnuts, plus adapter sets, clamp collars and installation tools. The company is family owned and operated.
