براغي رأس أسطوانية M6-1 X 75mm | محرك سداسي | ملولبة جزئياً | فولاذ مقاوم للصدأ 316 (100 / عبوة)

Pulled these out of the pack and the 316 stainless finish is flawless, no burrs or rough edges on the threads. They drive in clean with a hex key and the partial threading gives just the right grip for my jig setup. Exactly what I needed for a hundred pieces at this price.

I needed fully threaded M6 screws for a custom jig, but these 75mm ones with the partial thread let me tighten them cleanly into a blind hole. The 316 stainless steel feels way more corrosion-resistant than the cheap zinc-plated stuff I used before.

Finally found the right length for my jig fixtures and the 316 stainless is a relief for outdoor use. The hex socket drive seats firmly and doesn't cam out even under decent torque. These are definitely staying in my shop for good.
