T-Nut, with Four Prongs

Product Details

What is a T nut and when would I use one?

A T nut is a metal fastener designed to be knocked into a suitable panel or extrusion so it can accept an internal thread. It is commonly used when you want a repeatable fixing point, such as for assembling frames, machine guards, or furniture style structures where you may need to remove and refit components. This M5 version provides an internal thread for M5 bolts and screws.

Does this T nut use an M5 internal thread?

Yes, it has an M5 internal thread. That means you should use an M5 bolt or screw for best alignment and engagement. Using the correct thread size helps prevent stripping and gives a secure, reliable hold.

How is this T nut installed?

This model is installed by knocking in. Typically, you place the T nut into the correct location and knock it into position so the four prongs grip the material behind. Always ensure the hole size and panel thickness match the T nut requirements for a firm hold.

Will it grip securely on metal or galvanised sheet?

Because it is a four prong design, it is built to lock into place and resist turning during tightening. The galvanised finish also helps protect against corrosion in everyday use, making it a practical choice for workshop and general fixing applications.

Is the galvanised finish suitable for outdoor or damp environments?

The galvanised surface improves corrosion resistance compared with plain steel. If the assembly is regularly exposed to moisture, consider the rest of your fixings and materials as well, since durability depends on the full set of components. For many common external and protected outdoor uses, galvanised fasteners are a sensible option.

How many T nuts come in the pack and will I have enough for a project?

This product is supplied as a 100 pack. A full pack is useful for bigger builds, repeat assemblies, or when you want spares for replacements. If you are fitting multiple panels or making several identical units, ordering a 100 pack helps you complete the job without running short.

What part numbers should I reference when ordering?

The product part number is 031.00.446. Referencing the part number when ordering or checking stock can help ensure you receive the correct T nut specification, including the M5 internal thread and the D17mm format.
