Products Description
Twist Press Rivet Stud is a high-efficiency fastener that is installed on sheet metal or structural components using a press-fit process. Its unique external helical knurled structure creates a strong engagement during pressing, resulting in a bolt-like locking effect. This design achieves high-strength fastening without the need for welding or complex secondary processing.
Core Technical Features and Design Advantages
Spiral Knurling Structure Design
Twist-Clinch Fastener utilizes a high-precision spiral knurling process with a tooth pitch of 0.8-2.0mm and a trapezoidal tooth shape, the engagement area is increased by over 35% compared to ordinary straight knurling. This effectively avoids the risk of loosening under long-term vibration, making it suitable for high-precision applications such as battery systems.
Integrated Structure Design
The head and rod of the Spiral Knurl Press-In Stud are forged as a single piece, without welding joints, avoiding stress concentration and fracture. This increases tensile strength by 25% and extends service life. Two designs are available: countersunk (flat surface) and round (high load-bearing capacity) to suit different assembly requirements.
Guided Tail Design
The chamfered tail for Spiral Knurl Press-In Pin guides quick alignment with pre-drilled holes, improving installation efficiency, reducing sheet metal damage and assembly errors, ensuring installation consistency, and adapting to large-scale automated assembly, thus reducing labor costs.
Application Areas
New Energy Battery Systems
A large number of stable mechanical connection points are required in power battery modules, battery pack structural components, and energy storage system housings. Twist Press-In Fastener provide a reliable fixing method while avoiding the impact of welding on the battery structure.
Automotive Industry
Spiral Knurl Press-In Pins are widely used to replace welding and threading in automotive interior structural components, control module housings, and lightweight sheet metal structures.
Industrial Equipment
Automation equipment, mechanical structural components, and metal cabinets also extensively utilize Spiral Knurl Press-In Stud technology to improve assembly efficiency.
Quality Control and Certification
High-Precision Dies
All Twist-Clinch Fasteners are made using CNC-controlled stamping dies to ensure consistent height and spacing of each spiral.
Non-Destructive Testing
Internal defects are eliminated through magnetic particle inspection (MPI) or penetrant testing (PT) for Spiral Knurl Press-In Stud.
Dimensional Inspection
A coordinate measuring machine (CMM) is used to ensure all parameters of the Spiral Knurl Press-In Pin are within tolerance.
