براغي رأس أسطواني M2.5-0.45 × 30 مم | محرك سداسي داخلي | ملولبة بالكامل | فولاذ مقاوم للصدأ 316 (400/عبوة)

I needed precision screws for a small robotics jig, and the 316 stainless steel feels solid and corrosion-resistant. The hex socket drive made them easy to tighten in tight spots without stripping.

These are for a fixture I'm building, and the 30mm length with full threading grabs perfectly in tight spots. The 316 stainless feels dense and machined clean, not rough like cheaper alloy screws I've used. 400 in a pack means I won't run out mid-project.

Finally found some tiny 316 stainless screws that fit properly in my jig fixtures without stripping. The hex socket drive makes them easy to tighten precisely even in tight spots, and a full 400-pack means I won't run out mid-project.
