Product identity

The MIDWEST FASTENER 69285 is a self-locking thread insert with an M8-1.25 internal thread size. It is manufactured from steel for use in hardware and automotive applications.

Suitable uses and limits

This insert repairs stripped threads and creates durable threads in softer materials such as aluminium or plastic. It is not suited for applications requiring a different thread pitch, diameter or a non-locking insert.

Build integration

The insert is installed into a pre-drilled hole to provide a permanent steel thread. It frees the surrounding material from carrying the thread load and removes the need to tap the base material directly.

Questions about this item

What tap size do I need to prepare the hole for this M8-1.25 insert?

Drill and tap the parent material to the M8 x 1.25 thread pitch before screwing the insert in.

Can I install this steel insert into an aluminium casting without damaging the threads?

Yes, the insert provides a harder steel thread in the softer aluminium, spreading the load and preventing pull-out.

How do I confirm the self-locking feature is gripping the bolt correctly after installation?

Thread a bolt in by hand; you should feel increasing resistance as the locking coils engage, and the bolt should not spin freely when tightened.
