براغي غطاء مقبس 3/8-16 × 3 بوصة | رأس منخفض بمحرك سداسي | خيط كامل | فولاذ سبائكي معالجة حرارية سوداء (100/عبوة)

Good fit for my milling machine's T-slots—the low head profile cleared my clamps without any interference. The black oxide finish looks consistent across all 100 pieces, and the hex drive seated firmly in my Allen key.

Installing these into my jig fixture was a breeze; the hex socket drive grabbed perfectly without any stripping. The black oxide finish gives them a nice, uniform look that resists fingerprints better than plain steel.

I needed a dozen for a jig rebuild and these seated perfectly without any binding. The low head profile gave me just enough clearance under the mounting bracket where standard caps wouldn't fit.
