Frequently Asked Questions

Q: What aluminum extrusion size are these T-nuts compatible with?

A: These European T-nuts are specifically designed for 20×20mm T-slot aluminum extrusion profiles. They are not intended for other sizes such as 30×30mm or 40×40mm extrusions.

Q: Can I insert these T-nuts after the aluminum extrusion frame is already assembled?

A: Yes! One of the key advantages of this slim T-nut design is that they can be dropped directly into the T-slot at any time during or after assembly, eliminating the need to fully disassemble your frame for modifications or additions.

Q: What bolt thread size do these T-nuts accept?

A: These T-nuts feature an M4 thread (M4×10×6mm spec), making them compatible with standard M4 bolts and fasteners commonly used in aluminum extrusion systems.

Q: How durable are these T-nuts for long-term use?

A: Each T-nut is made from carbon steel with a nickel-plating finish, offering excellent strength and corrosion resistance to withstand regular mechanical stress in workshop and fabrication environments.
