Overview
Whittet-Higgins CNB-14 Clamp nut
The Whittet-Higgins CNB-14 is a one-piece, mechanically self-locking clampnut cut to inch threads for retaining, locating and preloading bearings and components on threaded shafts, ball screws and linear actuators. It is secured by a tangential (X-axis) socket-head cap clamp screw that draws the nut tight against the shaft thread, holding the assembly against vibration, shock and torque without a separate locknut or lockwasher and without damaging or requiring cutting of the shaft threads.
It installs faster than a traditional locknut-and-lockwasher pair and allows infinite adjustment and preloading from a single access point. Built with a carbon steel base nut and a hardened alloy fastener, finished in black oxide with a wax coating for corrosion resistance, the CNB-14 is rated to a 300 degree F maximum operating temperature, meets and exceeds ANSI/ABMA 8.2-1999, and is 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.
