براغي HOLO-KROME 76504 M20-2.5 X 65mm رأس أسطواني | محرك سداسي | فولاذ سبائكي مؤكسد حراري أسود (10 / عبوة)

I needed a reliable fastener for a jig I was building, and the hex socket drive on these M20 screws made installation much easier than using a standard hex key. The black oxide finish looks tough, and they fit perfectly into the pre-tapped holes without any binding.

The black oxide finish on these M20 socket cap screws feels properly done—no rough edges on the hex drive, and they’ve held up through a few days of repeated installs on our jigs without any galling. The 65mm length seated perfectly into my fixture block with clean threads on the first go.

Threaded a whole fixture plate with these and every single one seated perfectly with no galling. The hex socket drive grabbed cleanly without any wobble.
