Threaded Mandrel for 3/8-16 Repairs

The Helicoil 2288-6 is a steel threaded mandrel designed for installing 3/8-16 thread inserts. It suits technicians and DIYers restoring damaged threads in automotive or industrial components.

Verify Thread Size Before Ordering

Confirm the damaged hole uses a 3/8-16 thread pitch before purchase. This mandrel works only with that specific size and matching Helicoil inserts. No other dimensions or thread standards are supported by this tool.

Fits Standard Helicoil Installation Workflow

The mandrel drives the insert into the pre-tapped hole during repair. It requires a compatible tap and the correct Helicoil insert kit for 3/8-16 threads. Using it completes the mechanical lock of the new thread.

Questions about this item

Does the Helicoil 2288-6 threaded mandrel come with inserts or taps, or must they be purchased separately?

The listing covers the steel threaded mandrel only. Inserts, taps and any installation tooling are not included and must be sourced separately.

How do I confirm the 3/8-16 size matches the repair I need?

The mandrel is cut for a 3/8-16 thread pitch. Match this specification to the damaged hole or bolt before ordering.

What does the 3/8-16 designation tell me about the threads this mandrel will produce?

It indicates a 3/8 inch nominal diameter with 16 threads per inch, so the repaired hole will accept standard 3/8-16 fasteners.
