MIDWEST FASTENER CORP 76862 Helical Insert M14-1.25 Steel 6 PK

M14-1.25 Steel Helical Insert 6 Pack

This six-pack supplies M14-1.25 helical inserts machined from steel for thread repair and reinforcement. Mechanics and fabricators use them to restore stripped holes or to create durable threads in softer base materials. Each insert installs into a prepared hole to provide a permanent, wear-resistant female thread. The kit suits professional workshops and serious DIYers who need reliable thread restoration.

For thread repair in steel, aluminium and cast parts

The inserts suit anyone fixing damaged M14-1.25 threads or adding strong threads to low-strength parent metal. They are not for metric sizes other than M14-1.25, nor for inch-series holes, nor for applications that require a locking or self-tapping insert style. Buyers needing different diameters, pitches, or insert types should look at other listings.

M14-1.25 thread size and 1.25 mm pitch

The single specification that decides fit is the M14-1.25 designation, meaning a 14 mm major diameter with a 1.25 mm thread pitch. Only holes tapped to this exact size and pitch will accept these inserts. Verify the damaged hole matches M14-1.25 before ordering.
