براغي رأس أسطواني M3-0.5 × 50 مم | محرك سداسي | خيط جزئي | ستانلس ستيل 18/8 (600 / عبوة)

Just finished a small jig project and these 50mm lengths were perfect for reaching through thicker brackets, no fiddly alignment needed. The 18/8 stainless feels solid and the threads cut cleanly even into harder aluminum. Glad I bought the 600 pack, they'll last me years.

The hex socket drive makes installing these in tight spots on my tooling jigs so much easier. For 600 pieces, the 18/8 stainless steel feels solid and should hold up well against corrosion.

I needed longer M3 bolts for a jig I'm building, and the 50mm length with partial threading gives me just the right grip without bottoming out. The hex socket drive makes installation a breeze.
