براغي رأس كبس M14-2 × 85 مم | محرك سداسي | خيط جزئي | فئة 12.9 من سبائك الصلب مطلي بالزنك (25 / عبوة)

Mounted these on a milling fixture and the partially threaded shank made alignment much easier. The zinc plating looks clean and consistent across all 25 screws, no burrs on the threads.

The hex socket drive seated the wrench perfectly with zero wobble, and the zinc plating looks factory-clean out of the pack. Threads ran smooth into my jig plate without any binding, which is exactly what I need for repeated tear-downs.

Installed these in a tooling fixture yesterday and the hex drive seated perfectly without any cam-out. The zinc plating looks clean and even, and the partial threading made alignment much easier than fully threaded bolts.
