Trailer Wheel Stud Bolt - M12 x 1.5 - Pack of 20

These stud bolts are compatible with a wide range of trailers, including popular brands like Ifor Williams, Knott, and Indespension, provided they use the M12 x 1.5 thread size.

The thread size is M12 x 1.5, meaning a 12mm diameter with a 1.5mm thread pitch.

You will need a 19mm spanner or socket to tighten the 6-sided head of the stud bolt into the wheel hub.

They are specifically designed for sealed-for-life hubs, commonly found on models like the Ifor Williams P6E. Always confirm your trailer's hub specification.

The total length of the stud bolt is 48mm, with a thread length of 20mm.

It means you receive twenty individual M12 x 1.5 Trailer Wheel Stud Bolts in this purchase, providing ample quantity for multiple wheels or as spares.

These are specifically designed for trailer applications. It is crucial to use the correct specification bolts for your vehicle; using these on a car may be unsafe and is not recommended.

Check for cross-threading or debris in the hub's threaded holes. Ensure you are using an M12 x 1.5 bolt; mixing thread sizes can cause damage.

Verify the bolt head is hexagonal and not damaged. Ensure you are using a correctly sized 19mm tool.

The threads in the hub may be stripped. The bolt is not engaging properly. This requires inspection and potential repair or replacement of the hub.

Ensure the stud bolt is fully seated and that the wheel nuts are the correct type (e.g., taper seat) and size for your wheel and studs.
