Pre-Assembly T Nut Size M6 for 2020 Aluminum Extrusion Pack of 100 (M6)

These are really handy on my cnc home build.

I ran into an issue with the factory M-LOK nuts being too thick to fit properly on my handguard, which meant I couldn’t mount any accessories because the nuts would hit the barrel. Another member mentioned he had the same problem and recommended the TOPINSTOCK T-Nuts since they have the same thread pitch as standard M-LOK screws. I decided to give them a shot, and they worked perfectly, giving me the clearance I needed to attach multiple accessories. The pack comes with plenty of extras, so they’re great to have on hand for future builds. If you're dealing with the same issue, these are a solid fix.

great nuts

Sub-standard quality in channel contacts compared to edges on dozens of others. The corners of the edges are rounded on every piece. It appears sanded by hand prior to finish coating. Some are curved so much that it only contacts in the middle. This reduces the contact surface to the channel of the extrusion. The vendor markets the product in images to be superior to the hammerhead style by contact surface.

Sirve, pero no es de buena calidad. hay que limar los bordes para que entre bien en el aluminio

Just push a 009 o-ring underneath the nut. It hooks right on the protrusion. Then insert the nut into the extrusion as usual and presto, the nut stays where you push. Fantastic!

I needed M5 t-nuts to mount 20mm linear bearing rail on 25 series 80/20 extrusions for my CNC upgrade. These are designed for 20 series rail but they still fit well with enough bite to work. I torqued a few well beyond m5 spec and they did not strip out. The threads seemed perfectly formed in all the ones I used (about 3/4 of the pack).

Product (metal nuts) was good but for the oddest reason came heavily perfumed, to the point I had to put them outside. Probably done with best of intentions but caused me a major headache (literally).
