M4 Stainless Steel Round Rivet Nut For Thin Sheet

Product introduction

M4 rivet nut is a high-strength fastener with single-sided riveting. It is cylindrical in shape, has a standard M4 metric thread in the inner hole, and has a flange on one end. It is designed to provide a strong internally threaded connection point on substrates such as sheet metal, profiles or pipes that cannot be tapped or are not easily accessible from the back. When installing, there is no need to touch the back of the workpiece. Put the rivet nut into the prefabricated hole, use a special rivet gun or hand tool, and pull the tail of the barrel to plastically deform, expand and stick to the base material, thereby forming a permanent, high-strength internally threaded sleeve. This product perfectly solves the problem of insufficient connection strength of thin-walled parts, and has the functions of connection, load-bearing and thread protection. It is widely used in sheet metal chassis, auto parts, aerospace, electronic equipment cabinets, furniture assembly and other fields. Made of carbon steel, stainless steel or aluminum alloy, it has excellent tensile strength and torque resistance, making it an ideal solution for efficient and reliable single-sided connections.

 

Product features

1. Single-sided construction to solve the problem of blind spots

This is its core advantage. Installation only needs to be performed from one side of the workpiece without touching the back, which perfectly solves the fastening problem in scenarios such as closed profiles, pipe fittings or boxes that cannot be operated from the back.

 

2. Provide high-strength internal threads

It can embed a strong M4 internal thread on low-strength substrates such as thin plates and plastics. It greatly improves the wear resistance and connection strength of the thread, effectively prevents thread slipping, and can withstand high pulling force and torque, allowing multiple repeated disassembly and assembly of bolts.

 

3. Reliable connection, anti-seismic and anti-loosening

After installation, the tail of the rivet nut expands and deforms, tightly fitting with the base material, forming a permanent connection point. This structure has excellent anti-vibration and anti-loosening properties, and the connection is stable and reliable.

 

4. Applicable to a wide range of materials, cost-effective and efficient

Not only suitable for various metal sheets, but also for carbon fiber, plastic and other materials. The installation process is quick and easy, greatly improving production efficiency and reducing the difficulty and risk of tapping directly on fragile materials.

 

Product application

1. Sheet metal and chassis cabinets: This is the most classic application area. It is used to install panels, guide rails, circuit boards or other components on thin-walled panels of electronic equipment chassis, server cabinets and communication chassis, avoiding the problem of insufficient strength of direct tapping on easily deformable thin boards.

 

2. Automobile and transportation: widely used in automobile bodies, doors, chassis parts, interior panels, and interior decoration of high-speed trains and buses. For fastening wire harnesses, brackets, decorative parts or access covers, ideal for fastening on closed cavity structures.

 

3. Home appliances and furniture industry: used in the assembly of washing machine casings, air conditioning panels, control boxes, metal office furniture, and display racks. The installation can be completed on the exterior surface, keeping the interior clean and tidy, and the connection strength is high.

 

4. Aerospace and high-end equipment: In parts such as aircraft skins, internal partitions, and equipment compartments that require extremely high weight and reliability, lightweight alloy or stainless steel rivet nuts are used to fix various equipment and panels.

 

5. General industrial manufacturing and maintenance: It is a very flexible and reliable solution in the installation and later modification of mechanical equipment covers, pipe supports, and automation equipment frames. It is especially suitable for maintenance occasions where space is limited and cannot be operated from the back.

 

FAQ

Q: What are the main advantages of M4 rivet nuts?

A: Its core advantage is "single-sided construction", which allows installation to be completed without touching the back of the workpiece. It can provide a high-strength, removable M4 internal thread on fragile thin plates (such as sheet metal, plastic), greatly improving the load-bearing capacity and durability of the connection point.

 

Q: What tools are needed to install M4 rivet nuts?

A: A special riveting gun is required, which is divided into manual, pneumatic and electric. During installation, a blind rivet bolt matching the thread specification (M4) of the rivet nut must be used.

 

Q: How much force can M4 rivet nuts withstand?

A: The load-bearing capacity depends on the material and specifications of the rivet nut and the thickness and strength of the base material. Please refer to the technical data sheet provided by the manufacturer for specific values. Generally speaking, steel rivet nuts are stronger than aluminum.
