The Whittet-Higgins HTW-15 is a hardened tongued washer designed to be used with all Whittet-Higgins bearing and shaft locknuts to lock and retain bearings and power-transmission assemblies. Its internal key (tongue) seats into a keyed shaft to limit radial movement, while the hardened body protects softer lockwashers and serves as a precision spacer against heavy rotational thrust loads. Rated to 350°F maximum operating temperature and finished in black oxide with a wax coating to inhibit corrosion.

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.
