​​Ball Spring: This feature incorporates a small ball bearing and spring mechanism that applies outward pressure, holding the T-nut in position within the T-slot prior to tightening. This prevents the nut from moving or rattling during transportation or assembly, especially in vertical applications.

​

Flexible Handle: (or Spring Tab): Similar to the Ball Spring, a flexible handle or leaf spring is used to keep the T-nut firmly seated in the channel, preventing it from rotating or sliding out of position before the bolt is fully torqued.

​

Set Screw: T-nuts with a set screw offer a superior locking mechanism. The set screw is tightened against the inner wall of the extrusion, providing a secure, vibration-resistant lock that prevents the T-nut from shifting even under dynamic loads.​

​

Slide-In: This refers to the basic T-nut design, which relies solely on the tension of the tightened bolt to hold it in place. While cost-effective, it is best suited for applications where the T-nut is installed and immediately secured.

 

We stock T-nuts with a wide range of thread sizes to ensure compatibility with both Imperial (UNC) and Metric fasteners, catering to various load requirements and industry standards:
