Overview
Whittet-Higgins WI-03 Lockwasher for sixteen threads per inch locknut
The Whittet-Higgins WI series is a fractional-bore bearing lockwasher made of carbon steel and built to the ANSI/ABMA 8.2-1999 specification. Used together with the matching NI series locknut, it secures, locks, and retains bearings and power transmission components on a shaft, delivering accurate angular positioning through numerous locking positions that guard against loosening from vibration, shock, and torque.
The tabbed washer installs without special tools and performs effectively on both soft and hardened shafts. Manufactured in the USA and RoHS compliant, the WI lockwasher carries a maximum operating temperature of 300°F.

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.
