M10-1.25 self-locking thread insert
The Midwest Fastener 69287 is a steel insert that creates a secure M10-1.25 thread in damaged or soft parent material. It suits automotive repair shops and maintenance technicians who need to restore stripped holes without replacing entire components.
Installation and common issues
The insert is driven into a pre-tapped hole where its self-locking feature resists vibration loosening. Problems arise if the host hole is not tapped to the correct M10-1.25 specification or if the driving tool damages the insert's locking coils during insertion.
Limits of the thread standard
The M10-1.25 coarse pitch determines the load capacity and engagement length available for the repair. Softer base metals may still deform under high shear loads despite the steel insert. The repair is limited to holes that can accept this specific thread size and pitch.

Questions about this item
How can I verify the M10-1.25 insert is holding correctly after installation?
After threading the insert into the prepared hole, run an M10-1.25 bolt through it; the bolt should engage fully and resist loosening under vibration, confirming the self-locking feature is active.
What comes with part 69287 and what must I supply?
The package contains the steel self-locking thread insert only; you will need a matching tap for M10-1.25, a suitable installation tool, and the parent material drilled to the correct pilot diameter.
When should I choose the M10-1.25 version over other sizes?
Select the M10-1.25 insert when the damaged or new hole requires a 10 mm nominal diameter with a 1.25 mm pitch; other diameters or pitches will not match the existing threads.
