براغي رأس أسطواني سداسية داخلية M20-2.5 X 90mm | محرك سداسي داخلي | سنون جزئية | فولاذ مقاوم للصدأ 316 (25 / Pkg.)

Was tired of cheap bolts stripping out on my jig builds, but these 316 stainless screws hold up perfectly with a clean hex socket fit. The partial threading gives me just the right grip depth for precision assemblies. Solid choice for the price.

Used these for a jig I was building outdoors, and the partially threaded design made alignment much easier than fully threaded bolts. They feel sturdy and the hex drive seated perfectly with my socket.

The 316 stainless steel is noticeably heavier and more corrosion-resistant than the 304 stuff I used to buy. Threads were clean and the hex socket drove smoothly with no binding. Exactly what my jig needed.
