T Nuts

T nuts

T nuts (also known as T-slot nuts or hammer nuts) are threaded fasteners that look like the letter “T” and are designed to prevent parts from loosening and rotating during installation. It conforms to ISO, GB, ASME, DIN, JIS and other standards. It is available in diamond, square and other forms, through the slot can be quickly installed and high-strength fixed. Widely used in scenarios that require adjustable positioning.

Frequently Asked Questions

The “T” shaped flange of the T-nut is designed to lock laterally in the groove to avoid rotational loosening.

Pre-drilled holes are 70% of the large diameter of the threads, and hardwoods require shims to distribute the pressure.

The flange width should be 0.5-1mm less than the slot width, and the thickness should not exceed 2/3 of the slot depth.

The tensile strength of 304 stainless steel is ≥500MPa, 316 hardening treatment is available for special needs.
