Riley ★★★★★ Oct 22, 2026

Just set up a new jig and these T-slot nuts held perfectly thanks to the heat-treated black oxide finish. The inch sizes I ordered matched my track precisely.

I grabbed a few metric sizes for my 8020 rig, and the heat-treated steel feels much sturdier than the cheap zinc ones I used before. The black oxide finish also slid smoothly into the extrusion channel without any binding.

The black oxide finish on these nuts looks clean and should resist rust well in my shop. I grabbed a few metric sizes and they fit my aluminum extrusions perfectly without any slop.
