براغي رأس مقبس M12-1.75 × 90 مم | محرك مقبس سداسي | خيط جزئي | ستانلس ستيل 316 (25 / عبوة)

Installed about a dozen of these on a welding jig today and the 316 stainless threads cut smoothly without galling, even with a standard hex key. The partially threaded design gave just the right grip for our 40mm plate sandwich.

Installed a batch of these on a new jig frame and the 316 stainless finish is flawless right out of the bag, no burrs or blemishes on the threads. Partial threading made alignment in the fixture quick, and the hex sockets seated firmly on my driver without any wobble. Solid hardware for precision wo

The hex socket drive bit into my wrench with zero play, and the 316 stainless finish feels properly marine-grade. I used these for a custom jig build and they held alignment perfectly through a full day of heavy clamping.
