مسامير رأس مقبس 1/4-20 × 3/8 بوصة | محرك سداسي منخفض | خيط كامل | فولاذ مقاوم للصدأ 316 (200 / عبوة)

Used a handful of these to replace some worn-out fasteners on my CNC jig, and the 316 stainless held up perfectly against coolant spray. The low head profile was exactly what I needed for tight clearance, and the hex socket drive made installation a breeze.

Finally, a fully threaded 1/4-20 screw in 316 stainless that doesn't strip out on me during assembly. The low head is perfect for tight spots on my precision jigs where clearance is always an issue.

Installed a set of these on a custom jig I’m building, and the low head profile saved me exactly the clearance I needed. The 316 stainless feels solid and the hex socket drives cleanly without stripping—nice upgrade from standard zinc.
