براغي ذات رأس أسطواني M3-0.5 × 35 مم | محرك سداسي | ملولبة بالكامل | فولاذ ستانلس ستيل 316 (400 / عبوة)

Packed a jig for a prototype run and every single screw seated cleanly without any binding. The 316 stainless finish looks clean and gives me confidence they'll hold up in a slightly damp shop environment.

The hex socket drive grips perfectly with my Allen key—no stripping even at full torque. All 400 pieces arrived clean and uniform, thread engagement was smooth in my jig setup. For the price, you're getting solid 316 stainless that won't corrode in a damp shop.

Cut one of these M3-0.5 screws and the 316 stainless feels noticeably denser than the 304 I've used before, no burrs on the threads either. Perfect for my jigs.
