Overview
Whittet-Higgins KM-064
The Whittet-Higgins KM-064 is a metric bearing locknut manufactured to meet and exceed the ISO 2982-2:2013(E) specification. Threaded onto a shaft, it secures, locks, and retains bearings and power transmission assemblies while delivering accurate angular positioning through numerous locking positions.
It is used together with matched MB series lockwashers: an external tab on the lockwasher bends into a slot on the locknut to prevent the assembly from loosening due to vibration, shock, and torque, with no special tools required for installation. Made from carbon steel, it is effective on both soft and hardened shafts, rated to a maximum operating temperature of 300°F, 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.

FAQ
KM-064 questions & answers
What size is the Whittet-Higgins KM-064?
The Whittet-Higgins KM-064 is a locknut. Thread: M32 × 1.5 (pitch 1.5 mm). Outside diameter: 48.0 mm (1.890 in). Face diameter: 40.0 mm (1.575 in). Width: 8.0 mm (0.315 in). These are Whittet-Higgins' maximum sizes from its spec sheet.
What thread does the KM-064 fit?
The Whittet-Higgins KM-064 fits a M32 × 1.5 right-hand shaft thread (pitch 1.5 mm).
Does the KM-064 need a lockwasher?
Yes. Whittet-Higgins matches the KM-064 with the MB-064 or MBA-064 lockwasher. The washer's inner tab sits in the shaft's keyway, and after tightening one of its outer tangs is bent into a slot of the locknut so the nut cannot turn.
What tool installs the KM-064?
Whittet-Higgins' BASM-064 assembly socket: it holds all four spanner slots and takes a square-drive ratchet or torque wrench. To clean or repair the shaft thread first, Whittet-Higgins makes the RTDM-064 rethreading die.
What temperature can the KM-064 take?
Whittet-Higgins rates the Locknut KM series (metric) for up to 300 °F (149 °C).
What is the KM-064 made of?
Locknut: carbon steel.
Is there a drawing or CAD model of the KM-064?
Yes. Whittet-Higgins publishes a part print (PDF) and a 3D CAD model (STEP) for the KM-064. The drawing on this page is made from the same catalog dimensions.
How do I install the KM-064?
Follow Whittet-Higgins' assembly instructions for this part (PDF). Fit the lockwasher with its inner tab in the shaft keyway, tighten the locknut to the bearing maker's preload, then bend the nearest tang into a slot.
Is this a genuine Whittet-Higgins locknut?
Yes. Apollo Industries is an authorized Whittet-Higgins retailer, and every Whittet-Higgins part we sell is genuine, made by Whittet-Higgins in Central Falls, Rhode Island, USA.
Do you ship the KM-064 the same day?
