What is insert nut?
Insert nut, also known as a threaded insert, is a fitting that provides a threaded structure for the plate, similar to a rivet nut.
It has a circle of special organization on the periphery, and it is installed into a pre-drilled hole to prevent it from rotating. It has standard threads inside, can be subsequently installed Screws and accessories.
Can be used for wood, metal, sheet metal, aluminum and other composite materials.
Types of threaded insert nut
Thread Insert nuts can be divided into three main types according to the installation method: screw-in type, knock-in type and hot melt type.
According to their external structural characteristics, these nuts are further subdivided into A type, B type, D type, E type, I type, P type, T type and other categories.

Threaded insert nut for wood, external anti-slip teeth with metric threads inside
Nut dimensions: M3 M4 M5 M6 M8 M10
Drill size: 4MM-10.8MM

It has the same structure as Type A, with an additional flange on the head, which is also used for wooden boards.
Nut dimensions: M3 M4 M5 M6 M8 M10
Drill size: 4MM-10.8MM

Coarse thread on the outside, hex drive groove and flange on the other end.
Nut dimensions: M3 M4 M5 M6 M8 M10
Drill size: 4MM-10MM

The external thread with multiple structures can fix the nut more strongly, and the head does not protrude, so it can be better embedded in the plate.

Drill size: 4MM-10.8MM
Also called claw tee nut, it has a disc structure at the head and four claw-shaped structures at the bottom, which can be embedded into the surface of the plate by hammering to form a stable structure.
Standard:DIN1624
Size: M5-M14

Hot-melt nut is a kind of nut made of brass material and cylindrical structure, with knurling or tooth design around the outside, which is embedded in plastic parts after heating.
Standard:DIN16903
Nut dimensions: M2 M2.5 M3 M3.5 M4 M5 M6 M8 M10
Drill size: 1.6MM-8MM

Stainless steel threaded embedded nuts are also used for wood structures. There are threads inside and outside, and they can be installed by drilling pilot holes.

Drill size: 1.6MM-8MM
It is a threaded insert nut fixed by riveting. It is mainly used for thin metal plates or plastic plates and needs to be installed with professional tools.

Application scenario about threaded insert nut
Threaded insert nuts have been widely used in electronic equipment, furniture manufacturing, mechanical equipment, automobile manufacturing and other fields because of their high strength and easy installation.
Electronic devices: Threaded insert nuts are used to fix components such as electronic components, circuit boards and housings, such as computers, mobile phones, televisions, and tablets.
Furniture manufacturing: In furniture manufacturing, wood insert nuts are used to fix various connectors of furniture, such as wooden beds, wooden tables, chairs and benches, etc.
Mechanical equipment: In the assembly of mechanical equipment, Hot melt brass threaded insert nuts are also used in many places. For example, hot-melt embedded nuts are used in the parts assembly of 3d printers.
Automobile manufacturing: In the automobile manufacturing process, embedded nuts are widely used in the assembly of body structures and other parts.

There are many types of T nuts, including T slider nuts, t Slot Nut, T climbing nut, Furniture Four Claw T Nut. Where T climbing nut and Four Claw T Nut Also belongs to the category of thread embedding. The other two categories do not belong to this category.
1.Determine the borehole size: First, consult the corresponding table to determine the correct borehole diameter according to the required embedded nut specifications.
2.Clean the pilot hole: After drilling the pilot hole, be sure to thoroughly clean the metal chips and other debris in the hole.
3.Install the insert nut:
- For smash-in insert nuts: Use a hammer to gently tap the bottom of the nut, taking care not to install the nut backwards. Keep tapping evenly until the top of the nut is flush with the surface of the connector. This step requires caution to avoid damaging the nut or connector.
- For screw-in threaded insertnuts: Use an allen wrench to slowly screw in the nut from the other end of the mounting surface. Make sure that the wrench and nut fit tightly to avoid slipping. During the screwing-in process, keep the force uniform until the nut is completely fixed in the predetermined position.
Through the above steps, the correct installation of the threaded insert nut can be ensured.
