براغي غطاء مقبس HOLO-KROME 72246 1/2-13 × 3-1/2" | محرك مقبس سداسي | فولاد سبائكي مؤكسد أسود حراري (25 / عبوة)

Needed a solid 1/2-13 screw for a jig I was building, and these threaded in smoothly without any binding. The chamfered end made starting them by hand much easier than I expected.

The black oxide finish held up fine during assembly, no flakes or residue on my hands. These 1/2-13 caps threaded cleanly into the steel plate I’m working on, though I wish the package had a few more for the price.

The black oxide finish on these 1/2-13 screws feels really durable, and they threaded smoothly into my jig without any binding. I’ve used them for a few small assemblies now, and they hold tight; just wish the package included a few extras for the price.
