Value Collection BDKP36421 Thread Locking Insert M12 X 1.75

Product Description

The VALUE COLLECTION BDKP36421 is a carbon steel thread locking insert designed for thread repair applications where an existing hole has damaged or stripped threads. The insert features an M12 x 1.75 internal thread and a 3/4-10 external thread, allowing a metric-threaded fastener to seat securely in a repaired bore. Overall length is 0.656 inches. The bright finish carbon steel construction provides solid holding strength in standard thread repair scenarios. This type of insert is installed by machinists, maintenance technicians, and field service professionals working on equipment with worn or cross-threaded bores.

This insert is suited for metric coarse thread repair in ferrous and non-ferrous base materials where restoring an M12 x 1.75 thread engagement zone is required. Typical applications include repair of tapped holes in machinery housings, engine components, and structural assemblies where a 3/4-10 external drive accommodates standard installation tooling. The package quantity is 2 inserts per unit.

Compatibility

Designed as an OEM-style thread repair insert for tapped holes requiring an M12 x 1.75 internal thread restored via a 3/4-10 external thread interface in standard metric coarse applications.

Installation Notes

Installation is typically performed by a machinist or qualified maintenance technician using appropriate thread repair tooling and a correctly sized tap for the 3/4-10 external thread bore preparation. Power down or lock out all energy sources on the host equipment before beginning any thread repair work. Do not exceed the torque capacity of the base material, and ensure the bore is clean and free of debris before driving the insert. Follow applicable facility maintenance and machinery safety codes during installation.
