MS21083N6 | 軍規螺紋嵌件（10／包）

Installing these into aluminum was straightforward, and the threads grabbed cleanly on the first try. The hex drive made seating them flush without stripping a breeze. A solid pickup for any general assembly job.

The hex drive on these thread inserts gripped firmly during installation, and the mil-spec threading held up well in a plywood jig I built. Each insert seated flush without stripping, which saved me from having to re-tap any holes. Exactly what I needed for durable fastening points.

Installed these in a metal bracket for a cabinet hinge and the threads held tight without spinning. Each insert seated cleanly and the imperial sizing matched standard hardware perfectly. Solid pack for general assembly jobs.
