براغي رأس كبس H20-2.5 × 35 مم من هولو-كروم 76804 | محرك سداسي | فولاد سبائكي أسود حراري (10 / عبوة)

Used these for a jig I was building and the M20-2.5 threads fit perfectly. The hex socket drive made installation a breeze even in a tight spot.

The black oxide coating is exactly what I needed for a tooling jig that sits on the bench all day—no rust spots after a week of light oiling. The hex socket drive takes a ball-end allen wrench without any wobble, and the M20 thread cut cleanly into my pre-tapped holes.

These bolts fit perfectly into my milling machine's jig, and the M20 threads cut through the tapped holes smoothly. The socket drive gave me a solid grip with my hex wrench without any stripping.
