براغي رأس أسطوانية M10-1.25 X 70mm بمقبس سداسي | محرك مقبس سداسي | ملولبة جزئيًا | فئة 12.9 سبائك فولاذ مطلية بالزنك (50/عبوة)

The threading is clean and precise, so they seated perfectly in my fixture plates without any binding. Sixty-five bucks for 50 of these in 12.9 alloy is a solid deal, and the zinc finish looks like it'll hold up fine in the shop.

Used these on a jig I was building and the partially threaded design saved me from having to stack washers. The hex socket drive makes tightening in tight spaces a breeze. Definitely holding up well under load so far.

Needed a high-strength bolt for a custom jig I’m building, and these 12.9 alloy steel screws definitely deliver with that zinc coating holding up well under some torque. The hex socket drive seated perfectly with my Allen key, no stripping issues.
