براغي ذات رأس مقبس 3/8-24 × 1-7/8 بوصة | محرك مقبس سداسي | ملولبة جزئيًا | فولاذ سبائكي مع أكسيد أسود حراري (60 / عبوة)

I was replacing the retaining bolts on a jig I use for milling, and these fit perfectly—the 3/8-24 threading seated smoothly with no binding. The partially threaded shank gave me just the right grip depth for the application.

The black oxide finish on these screws looks really clean and hasn't shown any wear after a few days of heavy use on my jig. The threading is precise and they seated perfectly in my fixture without any wobble.

I needed these for a jig I was building, and the partial threading made alignment much easier than fully threaded bolts. The hex socket drive engaged cleanly without any stripping, which was a relief.
