Description

Overview

The Rubery Owen metric inner axle nut is the bearing adjustment nut used in compatible metric trailer wheel-end assemblies. Its 95mm across-flats size, 63mm internal opening and 9mm thickness distinguish it from similar imperial inner axle nuts.

Features

• Metric inner nut for Rubery Owen Moss wheel-end assemblies.
• 95mm across flats for matching the original nut and service tooling.
• 63mm internal diameter with a compact 9mm thickness.

Specifications and Materials

Across flats: 95mm. Internal diameter: 63mm. Thickness: 9mm.

Part number: AP4017.

Compatibility and Fitment

Check that the axle uses the metric Rubery Owen arrangement and compare the 95mm A/F, internal thread opening and 9mm thickness with the removed nut. The similar imperial inner nut is not interchangeable simply because its outside profile looks alike.

The following cross-reference numbers identify verified equivalent or replacement parts for this exact application. Confirm the selection-critical fitment details against the part being replaced before fitting.

Why Choose ICS Trailers

The important distinction with this nut is the metric wheel-end arrangement, because a similar imperial inner nut can appear almost identical on the bench. ICS Trailers can compare the old markings, nut dimensions and surrounding washer and outer-nut arrangement if identification is uncertain.

• Check the matching lock washer and outer nut during the same wheel-end repair.
• Use old markings and axle details to narrow down close-fitting variants.
