براغي رأس أسطواني M12-1.75 × 20 مم | محرك سداسي داخلي | كامل اللولبة | ستانلس ستيل 316 (50 / عبوة)

The hex drive fits my torque wrench perfectly, and the 316 stainless has held up well in a mildly corrosive jig setup I've been testing. No burrs on the threads either—just a clean, snug fit every time.

Was a little worried about the head height being too tall for my jig, but the 20mm length fits perfectly and the hex drive gripped tight without stripping. They're beautifully machined and feel solid in hand.

I needed some corrosion-resistant fasteners for a marine jig I’m building, and these 316 stainless steel screws are perfect. The fully threaded body grips tight without slipping, and the hex socket drive made installation a breeze.
