SOOS Rivet Nuts: The Key Force in Industrial Fastening
The core value of SOOS rivet nuts stems from their precise solution to the pain points of traditional fastening. In conventional industrial fastening, threaded connections on plastic parts or thin metal sheets (thickness ≤ 3mm) often face two major challenges: First, direct tapping easily causes the base material to crack and results in insufficient thread strength—especially on lightweight materials such as aluminum alloys and magnesium alloys, where threads are prone to stripping and failure after repeated disassembly. Second, although welded nuts can improve strength, high-temperature welding leads to base material deformation and thermal stress, and requires additional slag cleaning, which not only affects precision but also increases process costs.
SOOS rivet nuts, however, rely on the principle of "cold forming". With only the help of a pressure device, the knurled teeth or hexagonal structure of the rivet nut is pressed into a pre-drilled hole. The plastic deformation of the base material itself forms a tight engagement with the rivet nut—no high temperature, no cutting, and a single connection can be completed in just 3-5 seconds. This not only avoids damage to the base material but also increases thread strength by more than 30%, making it perfectly suitable for fastening thin and lightweight materials.
In terms of material and performance design, SOOS rivet nuts demonstrate strong adaptability to scenarios, covering the entire demand spectrum from general industry to extreme environments.

Basic models are made of high-quality carbon steel (e.g., 1018 low-carbon steel) and 304 stainless steel. After quenching-tempering heat treatment and Dacromet surface treatment, they can pass a salt spray test of over 500 hours, resisting corrosion in humid and weakly acidic environments to meet the general needs of home appliances and electronic devices.

For the lightweight trend in the automotive and new energy sectors, SOOS has launched aluminum alloy rivet nuts. With a density only 1/3 that of steel, they ensure a tensile strength of ≥ 200MPa while contributing to overall vehicle weight reduction.
-
For high-end scenarios such as aerospace and medical equipment, special models are made of titanium alloy and PEEK polymer materials. These not only offer excellent high and low-temperature resistance (-60℃ ~ 260℃) but also meet special requirements such as non-magnetism and biocompatibility. For example, in MRI medical equipment, titanium alloy SOOS rivet nuts avoid electromagnetic interference, ensuring the accurate operation of the device.
In terms of application scenarios, SOOS rivet nuts have been deeply integrated into multiple core industrial fields, acting as "invisible contributors" to improving production efficiency and product reliability.
-
In electronic manufacturing: The connection between the metal middle frame and plastic housing of smartphones and laptops requires high-strength threaded fixation on ultra-thin base materials (thickness of only 1mm). SOOS micro rivet nuts (minimum size M2) ensure no base material deformation through precise press-fit dimension control, while guaranteeing no thread stripping even after over 100 repeated disassembly cycles.
-
In the automotive industry: For the fastening of aluminum housings of new energy vehicle battery packs, traditional welded nuts easily cause housing deformation and affect sealing performance. SOOS aluminum alloy rivet nuts, through cold pressing, not only ensure an IP67 waterproof rating but also increase assembly efficiency by 5 times compared to traditional processes.
-
In medical equipment: For the connection between plastic panels and internal circuit brackets of ventilators and monitors, SOOS plastic rivet nuts not only have excellent insulation properties but also pass FDA biocompatibility certification, avoiding electrical conductivity risks and allergic issues that may be caused by metal materials.
Notably, the advantages of SOOS rivet nuts also lie in their adaptability to smart manufacturing. Their standardized dimensions (compatible with international standards such as ISO, DIN, and GB) and stable press-fit processes can be perfectly integrated into automated production lines. Through robotic handling and precise pressing by servo presses, the entire process of "feeding-pressing-inspection" is automated. This not only controls the assembly error of a single connection point within ±0.02mm but also reduces quality fluctuations caused by manual intervention. Meanwhile, SOOS provides customized services—for special base materials (e.g., carbon fiber composites) and non-standard hole diameter requirements, it can quickly adjust the tooth structure and pressing parameters of rivet nuts to meet personalized fastening needs in niche fields.
As industrial manufacturing transitions toward "high precision, lightweight, and high efficiency", SOOS rivet nuts, with their innovative structural design, diverse material options, and wide scenario adaptability, have broken the limitations of traditional fastening processes. They serve as a key bridge connecting "thin/light base materials" and "high-strength requirements". From improving production efficiency to ensuring product reliability, from contributing to green weight reduction to supporting high-end innovation, SOOS rivet nuts are leveraging the power of "small components" to underpin the high-quality development of large-scale industries, becoming an indispensable key force in the modern industrial fastening system.
