Self Aligning Push-On Fastener

Illustration of a self aligning fastener for a round shaft with several types of caps

This development of the standard Starlock® Push-on Fastener is particularly useful for applications where the face of the fastener must be square to the axis of the shaft. This is achieved by the self aligning legs on the fastener which also give increased resistance to non-axial loads which may be transmitted from the adjacent part i.e. wheel to axle assembly.

Uncapped fasteners are available in:

Capped Fasteners

The majority of our Starlock® push on fastener range can be supplied assembled with a cap to conceal the fixing and enhancing the appearance.

Dome Caps, Axle Caps, Deep Axle Caps and Nylon Caps fasteners are available in a variety of materials:

Stainless Steel (S), Aluminium (K), Zinc Plated Mild Steel (A) and Nylon (N).
