Overview
Whittet-Higgins AN-17 Retaining nut
The Whittet-Higgins N/AN series is an inch-dimension bearing locknut machined from carbon steel and matched with W series lockwashers to secure, lock, and retain bearings and power transmission assemblies on a threaded shaft. The lockwasher seats against the nut and a tab bends into one of the nut's external slots, delivering numerous locking positions for accurate angular positioning while preventing loosening from vibration, shock, and torque. Installation requires no special tools, the nut is effective on both soft and hardened shafts, and it is interchangeable with the TAN series. The N/AN line meets and exceeds ANSI / ABMA 8.2-1999, carries a 300°F maximum operating temperature rating, 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.

FAQ
AN-17 questions & answers
What size is the Whittet-Higgins AN-17?
The Whittet-Higgins AN-17 is a locknut. Thread: 3.340-12 (84.84 mm, 12 threads per inch). Outside diameter: 4.406 in (111.91 mm). Face diameter: 4.031 in (102.39 mm). Width: 0.635 in (16.13 mm). These are Whittet-Higgins' maximum sizes from its spec sheet.
What thread does the AN-17 fit?
The Whittet-Higgins AN-17 fits a 3.340-12 right-hand shaft thread (84.84 mm, 12 threads per inch).
Does the AN-17 need a lockwasher?
Yes. Whittet-Higgins matches the AN-17 with the W-17 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 AN-17?
Whittet-Higgins' BAS-17 assembly socket: it holds all four spanner slots and takes a square-drive ratchet or torque wrench. Or the PAS-08-18 adjustable spanner wrench. To clean or repair the shaft thread first, Whittet-Higgins makes the RTD-17 rethreading die.
What temperature can the AN-17 take?
Whittet-Higgins rates the Locknut N/AN series (inch) for up to 300 °F (149 °C).
What is the AN-17 made of?
Locknut: carbon steel.
Is there a drawing or CAD model of the AN-17?

How do I install the AN-17?
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?
