براغي ذات رأس أسطواني 1-1/2-6 × 17 بوصة | محرك سداسي | ملولبة جزئيًا | فولاذ سبائكي مع أكسيد أسود حراري

The black oxide finish on these 17-inch screws helps them slide into tight spots without binding, and the hex socket drive makes installation straightforward with an Allen key. They handled the pressure in my jig setup without any flex.

The black oxide finish on these screws gives them a nice, uniform look that matches my tooling perfectly. The 17" length is exactly what I needed for a deep fixture assembly, and the hex socket drive makes tightening them down a breeze with my Allen wrench set.

Installed these on a jig that takes a lot of vibration, and the fully threaded portion held tight after a week of use. The black oxide finish also looks clean against the steel.
