Overview
Whittet-Higgins CNF16-14 Fine thread
The Whittet-Higgins CNF16-14 is a one-piece, fine-thread (UNF) clampnut that mechanically self-locks to position and preload bearings, sleeves and other components on a threaded shaft. It locks by tightening a tangential (X-axis) socket-head cap screw, which clamps the base nut onto the shaft thread to resist loosening from vibration, shock and torque while still allowing infinite adjustment and preloading.
Because it secures without damaging the shaft threads and needs no keyway, the CNF16-14 eliminates the traditional locknut-and-lockwasher pairing and installs faster. The standard CNF nut pairs a carbon steel base nut with a hardened alloy clamp screw and a black-oxide-with-wax finish, is rated to 300°F, and offers greater axial strength and finer adjustment than the coarse-thread CNC series. Stainless steel and aluminum alloy versions are also available.

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.
