They are compatible with the EU standard M8-40 T-nut rail. The bolts have been cut and polished precisely to fit the nut holes. And the nuts' bolts have clear threads, which can properly chamfer the T-nut, so you don't need to worry about loose screws. 【Easy to Use】The M8-40 stainless steel rail groove kit is very easy to use in industry and convenient for connecting aluminum profiles to other parts.

The high-quality steel material is not only strong and durable but also rustproof and corrosion-resistant. The rust-resistant aluminum steel nuts are cut and polished with excellent craftsmanship, making the nuts smoother on the surface and easier to move, and making the T-nut rail more comfortable to use in aluminum profiles.
