High-Performance Tri-lobular Thread Rolling Screws

Product Description 

Our tri-lobular thread rolling screws are specifically engineered for direct integration into light alloy die-castings. Featuring a unique tri-lobular cross-section, these fasteners displace material during installation to form highly precise mating threads without the need for pre-tapping. The resulting interference fit provides exceptional self-locking and anti-loosening performance, ensuring maximum joint integrity under dynamic loads. By eliminating secondary tapping operations, these screws significantly streamline assembly processes and reduce overall manufacturing costs.

Industry Applications 

The definitive solution for high-efficiency fastening in non-ferrous metals:

• NEV Battery Packs: Secure assembly of aluminum and magnesium alloy enclosures.

• Light Alloy Die-Castings: Direct fastening for structural components in automotive and aerospace.

• Precision Machinery: High-speed assembly for complex electromechanical housings.

• Core Value: Optimized for high-reliability connections in soft metals where rapid, chip-free installation and superior pull-out resistance are required.
