براغي رأس أسطواني M8-1.25 X 90mm | محرك سداسي داخلي | ملولبة جزئيًا | فولاذ مقاوم للصدأ 316 (50/عبوة)

The 316 stainless steel is the real deal here—no rust spots even after a week of coolant spray on the mill. The hex socket drive seated perfectly with my Allen key, and the partial threads gave my fixture just the right grip. Ordered another pack already.

Needed some strong bolts for a jig I was building, and these 316 stainless screws are exactly what I was after. The partial threading gave me plenty of grip in the base plate without needing extra washers.

The hex socket drive on these is machined cleanly, so my allen key seated perfectly without any wobble when torquing them into my jig frame. I've used cheaper stainless bolts before, but the 316 material here feels noticeably more corrosion-resistant for the damp shop environment.
