APPROVED VENDOR Key Locking Insert: Thin Wall, 2 Keys, 1/4"-28 Int Thrd Sz, 3/8"-16 Ext Thrd Sz

A key locking insert, like the APPROVED VENDOR thin-wall type, is used to repair or reinforce tapped threads in metal assemblies. It provides a durable, reusable internal thread (1/4"-28) in softer materials, with external threads (3/8"-16) locking into the host component via two keys to prevent rotation under load.

This thin-wall insert has a 1/4"-28 internal thread size and 3/8"-16 external thread size, with fine threads and a plain finish. It is made from C1215 material, includes 2 keys, and comes in a 10-pack. The external thread fit is 2A and internal thread fit is 2B, compatible with a 3/8"-16 tap.
