Working Principle and Installation Guide of DIN 1624 4-Prong T-Nuts
A DIN 1624 4-prong T-nut is a type of internally threaded insert with four sharp prongs designed to anchor securely into wood, plywood, or composite panels. It provides a reliable threaded connection from the back side of the workpiece and is widely used in furniture manufacturing, wooden structures, displays, sports equipment, and more.
Built to DIN 1624 standards, the four prongs on the base dig into the material to prevent rotation or loosening during screw insertion or use. As a professional T-nut manufacturer, Xinchi is happy to introduce DIN 1624 T nuts to you.
Working Principle of DIN 1624 4-Prong T-Nuts
The functionality of 4-prong T-nuts relies on two main aspects:
Anti-Rotation Grip: The four sharp prongs are pressed into the base material, locking the nut in place and preventing spinning or pull-out under torque.
Threaded Connection: The center hole is tapped with a precision thread, allowing a bolt or machine screw to be inserted from the opposite side of the panel.
This structure ensures secure fastening while allowing repeated assembly and disassembly.
How to Install a DIN 1624 4-Prong T-Nut
Step 1: Drill a Mounting Hole
Drill a clean through-hole in the panel. The hole diameter should match the outer diameter of the T-nut barrel according to DIN 1624 recommendations for a snug fit.
Step 2: Insert the T-Nut from the Back
Place the T-nut into the hole from the back side, with the prongs facing the panel surface.
Step 3: Press the T-Nut In
Use a rubber mallet, arbor press, or clamping tool to press the T-nut firmly into the wood, ensuring all four prongs are embedded evenly and the flange sits flush.
Step 4: Insert the Screw from the Front
From the front of the panel, insert and tighten the screw or bolt into the threaded hole to complete the installation.
Tip: Press-fit tools or fixtures are recommended for production environments to improve installation consistency.
