براغي رأس مقبس M6-1 X 70mm | رأس مسطح بمحرك سداسي | خيط جزئي | سبيكة فولاذ درجة 12.9 مطلي بالزنك (100/عبوة)

Picked up a pack for a precision assembly project and the hex socket drive made installation a breeze. The partially threaded design held firmly without slipping. Exactly what I needed for the job.

I needed strong fasteners for a jig rebuild, and the 12.9 alloy steel on these feels rock solid compared to the usual 8.8 stuff. The flat head sits flush perfectly, and the partial threading made alignment much easier.

I replaced some worn-out screws in my milling machine jig with these, and the hex socket drive made installation much easier than using a standard Allen key. The zinc plating still looks clean after a month of use in a slightly oily shop environment.
