براغي رأس أسطوانية M6-1 × 70 مم | محرك سداسي | ملولبة جزئيًا | فولاذ سبائكي فئة 8.8 بأكسيد حراري أسود (200 / عبوة)

The 70mm length was exactly what I needed for a jig build, and the hex drive seated perfectly without any stripping. The black oxide finish looks clean and professional once installed, giving the assembly a finished feel.

Pulled these out of the pack and the black oxide finish is evenly applied, no rough edges on the hex socket. Threads engage smoothly into my jig plates, and the 70mm length with partial threading gives just the right grip for clamping.

The partial threading on these 70mm screws made them perfect for my jig assembly where I needed grip on the lower section. They torqued up smoothly with no binding.
