براغي رأس أسطوانية مقاس 1/2-13 × 1-1/2 بوصة | محرك سداسي برأس منخفض | ملولبة بالكامل | فولاذ سبائكي بطبقة أكسيد سوداء حرارية (50 / عبوة)

The low head profile lets me get a socket driver into tight spots on my tooling fixtures where a standard cap screw would never fit. The black oxide finish looks clean and seems durable enough.

I needed these for a jig I’m building, and the low head profile gave me just enough clearance under the plate. The hex drive seated perfectly with a standard 3/8" driver, and all fifty came with clean, consistent threads.

The black oxide finish on these screws held up perfectly during assembly, no galling or residue like cheaper coatings. Fit was exact in my jig’s tapped holes, and the low head cleared a tight clearance I couldn’t manage with standard caps.
