Overview
Whittet-Higgins NT-02 Locknut
The Whittet-Higgins NT-02 is a small-profile inch-series bearing locknut that secures, locks, and retains bearings and power transmission assemblies on a threaded shaft. Its reduced outside diameter and thickness make it ideal for limited-space applications and lighter axial loading.
The NT-02 is matched with WT series lockwashers: a washer tab seats into one of the locknut's many slots to provide accurate angular positioning and prevent loosening from vibration, shock, and torque. Machined from carbon steel, it installs without special tools on both soft and hardened shafts and meets and exceeds ANSI / ABMA 8.2-1999.

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.
