Threaded Four-Prong T-Nut For Machine Assembly

Product introduction

The four-claw nut is an innovative fastener designed specifically for thin sheet materials. Its unique feature lies in the four elastic claws distributed symmetrically at the tail. When installed, the claws are pressed into the preset holes through pressure. The claws quickly shrink inward and bite the plate firmly, forming a high-strength, anti-rotation permanent internal thread. This product eliminates the complex process of welding nuts or drilling and tapping on thin plates, greatly improving production efficiency and effectively reducing production costs. It is widely used in threaded connection scenarios of various metal or plastic sheets such as chassis cabinets, sheet metal structures, auto parts, electronic and electrical casings, etc. Four-claw nuts have become an indispensable fastening solution in modern industry due to their excellent anti-rotation and anti-falling performance and convenient installation method, providing a solid and reliable connection guarantee for your products.

 

Product Features

1. Excellent anti-rotation ability: Its four symmetrically distributed claws can firmly bite the hole wall after being pressed into the plate, forming strong anti-rotation resistance to ensure that it will not slip or rotate during screw tightening and use.

2. Extremely high resistance to falling off: The special design of the claws causes them to elastically deform after being pressed in, tightly clasping the back of the board like barbs, and can remain in place even if it is subject to strong vibration or impact, effectively preventing loosening.

3. Easy to install and extremely efficient: It adopts simple press-in installation without the need for welding, drilling, tapping or special tools. It can easily realize automated batch assembly, greatly improve production efficiency, and save labor and time costs.

4. Single-sided installation, wide applicability: Installation can be completed from only one side of the workpiece, especially suitable for closed or sheet metal structures that are operable on only one side, solving the installation limitations of traditional welding nuts or through-bolts.

5. Durable and reliable: usually made of high-quality steel, and can be provided with electroplating and other surface treatments as needed. It has good strength and corrosion resistance and can adapt to various harsh industrial environments.

 

Product application

1. Chassis cabinet and sheet metal structure: This is the most classic application field. It is widely used on the side panels, top panels, bottom panels and internal brackets of network server cabinets, communication chassis, power control cabinets, industrial consoles and other products. It is used to install guide rails, components, door locks or panels to provide reliable threaded connections.

2. Automotive industry and parts: It is used to fix various accessories, sensors and decorative parts on thin-walled parts such as automobile bodies, door interior panels, seat structures, engine peripheral brackets, and wiring harness fixing plates, and can effectively withstand vibrations during vehicle driving.

3. Electronic appliances and home appliance industry: often used in computer cases, air conditioner casings, washing machine control panels, audio equipment, instruments and meters, etc., to fix internal circuit boards, cooling fans, housing covers, etc., to achieve clean and efficient assembly.

4. Office equipment and furniture industry: In copiers, printers, file cabinets, metal desks, shelves and other products, it is used to connect panels, casters and adjustment parts to simplify structural design.

5. Heating, Ventilation and Air Conditioning (HVAC) and ventilation ducts: Used to fix access doors, covers and various functional components on air handling units, air ducts, filter boxes and other equipment.

 

FAQ

Q: Do the installation of four-claw nuts require special tools?

A: For small batch installation, you can use a hammer or ordinary riveting equipment to press in manually. In large-scale production, it is recommended to use pneumatic or electric riveting machines to ensure installation efficiency and quality consistency.

 

Q: When installing a four-claw nut, what are the requirements for the hole position of the plate?

A: There are strict requirements. It is generally recommended to use punched or drilled round holes, the diameter of which must exactly match the nut specifications. If the hole diameter is too small, it will cause installation difficulties or the claws will be damaged; if the hole diameter is too large, the clamping force will be insufficient, and the nut will easily loosen or rotate. Be sure to refer to the supplier's specifications to select the correct hole diameter.

 

Q: Can four-claw nuts be used on plastic or composite panels?

A: Yes. But it is more suitable for materials with certain strength and plasticity (such as ABS, nylon, etc.). When used on soft plastics or brittle materials, it is necessary to carefully evaluate the clamping force and the material's bearing capacity to prevent the material from being crushed or cracked.

 

Q: Is the anti-rotation and anti-falling performance of the four-claw nut really reliable?

A: Very reliable. Its four claws will generate strong radial stress after being pressed in, firmly "biting" the hole wall, providing excellent anti-rotation capabilities. At the same time, the structure on the back of the claw can be locked on the back of the plate like a barb, thereby achieving efficient anti-vibration falling off.

 

Q: Can four-claw nuts replace welding nuts?

A: It can be used in thin plate applications, and the advantages are obvious. It avoids thermal deformation caused by welding, requires no grinding, no welding slag, and is more efficient. However, where extreme structural strength is required or where extreme loads are required, welding may still be the preferred option.
