3-Hole T Nuts vs. 4-Prong T Nuts: What’s the Difference?

Postview: 0 views     Date: October 20, 2026

3-hole T nuts and 4-prong T nuts are used in different types of fastening applications, including furniture and wooden panels. The main difference is their base design. A 3-hole T nut has a round base with three mounting holes, while a 4-prong T nut has four prongs around the flange. As a professional T nut manufacturer, Xinchi Fastener Factory is glad to share the difference between 3-hole T nuts and 4-prong T nuts.

3-Hole T Nuts

A 3-hole T nut features a round base with three holes for mounting screws. The screws help secure the nut to the panel and keep it in position.

This type of T nut can be used in furniture, wooden panels, and other assemblies where a screw-mounted base is suitable. When choosing a 3-hole round base T nut, check the base diameter, thread size, and hole positions to make sure they match your design.

4-Prong T Nuts

A 4-prong T nut has four prongs that press into the material during installation. These prongs help hold the nut in place and prevent it from turning when a bolt is tightened.

DIN 1624 T nuts are a common type of four-prong T nut. They are widely used in furniture and woodworking applications where a threaded connection is needed.

Differences Between 3-Hole and 4-Prong T Nuts

The main difference between these two T nuts is how they are mounted.

A 3-hole T nut is fixed with separate screws, so the panel needs suitable mounting holes. A 4-prong T nut is installed by pressing its prongs into the material, which requires a properly sized hole for the threaded barrel.

The choice depends on the product design, panel material, and installation requirements. Thread size and dimensions should also be checked before ordering.
