براغي غطاء مقبس HOLO-KROME 68024 1/4-20 × 1/2" | رأس منخفض سداسي المقبس | فولاد سبائكي مع أكسيد أسود حراري (100 / عبوة)

Put these on a jig I'm building and the low head profile is exactly what I needed for tight clearance. The black oxide finish looks clean and seems like it'll resist rust well in my shop.

Installed these on a production fixture and the low head profile made all the difference in a tight clearance area. The black oxide finish looks clean and hasn't shown any wear after repeated adjustments.

Used a full bag of these on a custom jig for the shop, and the black oxide finish has held up perfectly against oil and grime without a speck of rust. The low head profile let me fit them into a tight spot where standard caps wouldn't go.
