Setting Method

Recommended Spin-Pull-Spin Installation Process

We recommend using the spin-pull-spin installation method for blind rivet nuts and studs. In this process, the rivet nut or stud is first threaded onto the mandrel by rotation, then inserted into the prepared hole. The tool subsequently applies a pulling force without rotation to deform and set the rivet nut body securely against the base material. After the proper setting is achieved, the mandrel is unscrewed and removed.

This installation method ensures consistent setting quality, reliable clamping force, and optimal performance in sheet metal and thin material applications.

Setting Tools and Installation Recommendations

Our complete range of blind rivet nut and stud setting tools is available in our catalog and on our website's Tools section. These tools are designed to accommodate varying material thicknesses, ensuring consistent and reliable setting results across different applications.

For simultaneous installation of multiple blind rivet nuts, press-based setting methods may be used. However, we strongly recommend consulting our technical team in advance to ensure proper tooling selection and process control.Mechanical screwdrivers or spanners are not recommended for blind riveting, as they may damage the internal thread surface and negatively affect the strength and reliability of the final connection.

Blind rivet nut materials:

Blind rivet nuts are manufactured from Steel, stainless steel, or aluminum. The materials we use have good deformability properties and high resistance to turning in the upset area. Standard stainless steel blind rivet nuts and studs are made from A1 or A2 austenitic steel containing 18% chromium and 10% nickel. Each material has its advantages: Steel = suitable for general use, Aluminium = low weight and corrosion resistance, Stainless steel = resistant to corrosion and temperature.

Flat head full hexagonal rivet nuts

This versatile head type is the one most commonly used in the industry. The arrow and V should point at the line between B and A, not at the gap created by deep-drawing.The idea is to demonstrate that the gap between B and A can be reduced to zero by deep-drawing.

Blind Rivets Nuts & Stud Fasteners for Sheet Metal

Extra-small countersunk head rivet nuts

This head type is used where the gap V is required to be small or zero. V can be reduced to zero by: using a collar to punch a slight depression in the parent material A, or by a slight countersinking of A. With malleable material, the gap V is automatically eliminated.

Blind Rivets Nuts & Stud Fasteners for Sheet Metal

Extra-small countersunk heads are an improved alternative to standard countersunk heads, as they do not require a countersunk hole. However, they should not be used if: the hole is out of tolerance, the parent material is malleable (as this could cause the head to pull through), or the screw exerts a lateral moment on the blind rivet nut.
Blind rivet nuts with extra-small countersunk heads are installed using setting tools with standard nosepieces.

Blind Rivets Nuts & Stud Fasteners for Sheet Metal

Countersunk head rivet nuts 

Countersunk heads generally require countersinking of the parent material. Therefore, a countersunk head is used when the gap V must be negligible, but an extra-small countersunk head cannot be used. We recommend that the countersinking (f) be made slightly shallower than the countersunk head so that the head projects slightly beyond the surface of the supporting part A and thus makes as much contact as possible with the attached part B (V > 0) (detailed information on dimension (f) can be found on pages 94and 104).

Surface Treatment Options

Standard steel blind rivet nuts and studs are supplied with a zinc-plated surface treatment. The standard finish is 8 μm zinc plating, available in yellow passivation or RoHS-compliant blue-white zinc, providing reliable corrosion protection for general industrial applications.

For automotive and high-corrosion environments, zinc-nickel alloy surface treatments are available in accordance with automotive industry standards, offering 720 to 1,000 hours of neutral salt spray resistance (NSS).

We would like additional surface finishes and coatings to meet specific performance and durability requirements.

 

Selecting the material

Standard is supplied in steel, aluminum, and stainless steel. The choice of material depends on the strength of the blind rivet nut and stud (see table page 89) and the required corrosion resistance of the completed end product. Our standard stainless steel products are suitable for use in the food and beverage industries. We would be pleased to provide you with further information on stainless steel or brass blind rivet nuts or about corrosion resistance.

 

Advice for optimum assembly

For the installation of large numbers of, and in particular when using stainless steel components, to obtain the best connection every time, we recommend that the mandrel be lubricated before installation starts and after that at regular intervals

How to Distinguish Between Blind Rivet Nuts and Self-Clinching Nuts

Blind rivet nuts and self-clinching (press) nuts are two common types of fasteners used for creating strong threaded connections in sheet metal and thin materials. Understanding the differences is essential for selecting the right solution for your application.

Blind Rivet Nuts

Blind rivet nuts, also known as pull rivet nuts or threaded inserts, are designed for single-sided installation. They are widely used in automotive, aerospace, railway, refrigeration, elevator, switch, instrument, furniture, and light-industrial assemblies.

Key features include:

Do not require welding or tapping of internal threads.

Ideal for metal sheets, tubes, and hollow sections

Provide strong, reliable threads without damaging the base materialEasy and fast installation with consistent performance

Blind rivet nuts were developed to overcome the limitations of traditional welded nuts, such as thread slippage or heat damage, and are suitable for various metals and lightweight assemblies.

Self-Clinching Nuts

Self-clinching nuts, also called press-fit nuts, are installed using column or sheet metal pressing, which plastically deforms the base material to lock the nut in place. They require:
The base material should be softer than the nut for proper deformation and secure fastening
Careful consideration of material hardness, especially with stainless steel or high-carbon steel, which may need special-strength nuts or additional welding
Key considerations:
Not ideal for stainless steel plates due to high hardness and crimping difficulty
Installation may be less secure if the material properties are not suitable.
Commonly used in low-carbon steel, aluminum, and copper sheet applications

Blind Rivet Nut Strength Testing Method

The following procedure outlines the standard method for testing the mechanical strength and torque performance of blind rivet nuts. Adhering to these steps ensures reliable, repeatable results and verifies compliance with product specifications.

01

Threaded Mandrel Load Test

Screw the blind rivet nut onto the threaded mandrel.

Apply a static load for 15 seconds.

Check that no fracture occurs. If the nut withstands the load, release the force and remove the nut.

During the test, the mandrel should be advanced at a controlled speed, not exceeding 3 mm/min.

If the mandrel or threads are damaged during testing, the results are invalid.

02

Ultimate Load Test

Screw the blind rivet nut onto the threaded mandrel.

Gradually increase the load until the nut fails.

Please make sure that failure does not occur at the junction between the head and cylindrical body.

Maintain a slow, consistent mandrel movement, up to 3 mm/min.

Any damage to the mandrel invalidates the test.

03

Riveted Plate Load Test

Rivet the blind rivet nut into a test plate according to the product’s recommended dimensions (thickness H and hole diameter D₀ or S₀).

Insert the test bolt without lubrication.

Apply axial pressure until the nut cracks or fails.

Ensure that the torque measurement error does not exceed the rated tolerance of the testing tool.

04

Torque and Anti-Rotation Test

Rivet the blind rivet nut into the test plate and tighten the test bolt without lubrication.

Apply torque until relative rotation occurs between the nut and the plate.

Ensure that the torque tester or tool has a measurement error within specified limits (h and d₀).

This testing method confirms the load-bearing capacity, torsional resistance, and secure-thread performance of blind rivet nuts, ensuring reliable application in sheet metal, tubing, and hollow-section assemblies.
