براغي ذات رأس أسطواني M12-1.75 × 110 مم | محرك سداسي | ملولبة بالكامل | فولاذ مقاوم للصدأ 316 (25 / عبوة)

Pulling these out of the package, the 316 stainless steel feels noticeably denser than the standard 304 ones I've used before. The hex socket drive engaged perfectly with my driver, no slipping at all. They fit the jig holes cleanly, exactly the length I needed for a marine grade assembly.

Used a full pack to rebuild a jig for repetitive drilling, and the 316 stainless held up perfectly under constant clamping torque. The hex socket drive made driving them in tight spots much easier than a Phillips head would have.

Installed these on a marine railing repair last weekend, and the 316 stainless held up perfectly against the salt spray without any sign of rust. The full threading made it easy to get a solid bite into the aluminum frame.
