براغي رأس أسطوانية مقاس 2-4-1/2 × 10" | محرك سداسي | ملولبة جزئيًا | فولاذ سبائكي مع أكسيد أسود حراري

Installed these in a jig for a production run and the hex socket drive allowed me to torque them down without any stripping. The 10" length was exactly what I needed for a deep assembly.

These black oxide screws threaded perfectly into my milling machine fixture, and the hex socket drive made installation quick with no stripping. The 10" length was exactly what I needed for this jig setup.

Needed these for a custom jig I’m building, and the 10-inch length gave me just enough thread engagement without having to stack washers. The black oxide finish looks consistent and should hold up well in my shop.
