Overview
Whittet-Higgins NS-34 Locknut
The Whittet-Higgins NS series is a stainless steel bearing locknut engineered to secure, lock, and retain bearings and power transmission components on threaded shafts. It is matched with WS series lockwashers, whose locating tab seats into a keyway and engages an external slot in the nut to provide positive locking and accurate angular positioning across numerous locking positions.
Built from corrosion resistant stainless steel for wet, washdown, and chemically aggressive service, the NS locknut prevents assembly loosening caused by vibration, shock, and torque, and works effectively on both soft and hardened shafts. It installs without special tools and meets and exceeds the requirements of the ANSI/ABMA 8.2-1999 specification.

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.
