Features of Custom Carbon Steel Rivet Nuts

Our custom rivet nuts redefine reliability in high-stress automotive applications, starting with an optimized super large head design. This expanded bearing surface distributes clamp force evenly, reducing sheet deformation by up to 40% versus standard rivet nuts while providing superior resistance to pull-through failure-critical for thin-gauge vehicle panels and chassis components.

A precision-applied nylon polymer patch is embedded beneath the head, creating a permanent, torque-retaining lock without compromising installation speed. This patented system prevents spontaneous loosening under extreme vibration (tested to 25 G-force) and thermal cycling (-40°C to 120°C), effectively eliminating costly re-torquing in powertrain, suspension, and safety-critical assemblies.

Application of Custom Carbon Steel Rivet Nuts

Carbon steel rivet nuts are used for strong, easy-to-install fastening in a wide range of applications, particularly when only one side of the material is accessible.

Securing interior and exterior panels, mounting engine components, and fixing hardware. Providing lightweight yet strong and durable connections in aircraft assemblies. They are common in the automotive and aerospace industries for securing body panels and structural components, as well as in general construction, electronics, and machinery.

Production Process of Custom Carbon Steel Rivet Nuts

Pretreatment: Carbon steel materials need to be spheroidized annealed. By heating the steel to the temperature range and then slowly cooling it, the layered cementite in the pearlite is transformed into a spherical structure.

Forming stage: The forming stage uses a multi-station cold heading process to continuously extrude the material through a precision mold. The standard process includes key steps such as bottom positioning, upsetting shaping, edge chamfering and center perforation.

Internal thread processing: The rolling forming process has become the preferred processing method for high-strength rivet nuts because of its advantages in maintaining the integrity of metal streamlines and improving the density of thread surface.

Heat treatment process: Taking material as an example, after quenching at 850℃ and tempering at 500℃, an ideal hardness value of 28-36hrc can be obtained, achieving the best balance between strength and toughness. Stainless steel material has good corrosion resistance and usually does not require additional heat treatment.

Surface treatment: Common processes include electrogalvanizing, dacromet coating, phosphating, etc.

FAQ

Q: How does your factory do regarding quality control?

A: The inspection department randomly inspects products every day and conducts full inspections through optical screening machines.

Q: What payment terms do you accept?

A: T/T or L/C or payment before shipment,others is welcome.

Q: How strong are steel rivnuts?

A: For example, a properly installed 1/4-20 rivnut in 0.030 rolled steel has a 480-pound pullout strength, so four will provide a significant margin for a 145-pound dead weight. Installation Tools: ASM uses appropriate installation tools to ensure proper setting of rivnuts.

Q: How to tighten a rivnut?

A: Put a wrench on the oversized nut to prevent it from spinning and a socket on the bolt head. Now, while holding the box wrench, start tightening the bolt. This will collapse the rivet nut on the back side and lock it into the hole. There's no need to go 'gorilla' on it, just stop when it won't tighten any more.

Q: What is the difference between open end and closed end rivet nuts?

A: Rivet nuts also come in two variations of end style – either open ended where the bolt can protrude through the rivet nut without obstruction, or a closed end type. Closed end type rivet nuts are ideal if you're looking for a sealed end rivet nut, providing an effective option for the ingress of water.
