Products Description
Spiral Knurl Press-In Stud is a structural fastening element embedded into metal sheets or malleable materials by the mechanical press-in method. Compared with welded studs or ordinary press-in studs, Twist Press Rivet Stud requires no thermal processing and does not change the substrate structure, making it particularly suitable for thin sheets, coated sheets or structural parts requiring surface treatment protection. This product is widely used in electrical cabinets, sheet metal structures, communication equipment, automation devices and various industrial enclosure systems.
For engineering customers, the core of press-in fasteners is not "whether they can be fixed", but "whether they are long-term stable and batch-consistent". The Spiral Knurl Press-In Pin we provide is designed and manufactured around this goal.
Core Advantages of the Product
Spiral Knurl Structure: The knurling of the Twist Press-In Fastener adopts a continuous progressive interlocking design. After being pressed into the sheet metal, it forms a laminated mechanical interlock with the base material, resulting in significantly higher pull-out resistance and torsional strength than straight-knurl and diamond-knurl studs. It remains stable without loosening or backing out under long-term vibration, impact and temperature variations, delivering a connection reliability close to an integrated structure, and fundamentally eliminates issues such as loosening, abnormal noise and failure.
Extremely Simple Installation: Only requires inserting the stud into the pre-drilled hole and completing the press-fit with a standard press or dedicated fixture. No tapping, welding, adhesive or locking is needed, greatly improving the production line tempo. The installation process of the Spiral Knurl Press-In Insert does not damage the plating or surface finish of the sheet metal, reducing the defect rate, helping overseas customers cut labor costs and increase productivity.
Full-Scenario Adaptability: The Twist Press Insert is compatible with all mainstream sheet metals including cold-rolled steel, stainless steel, aluminum alloy and copper alloy, breaking through the thickness limitations of traditional fasteners. It maintains high pull-out and torsional resistance even on ultra-thin sheets, solving the pain points of easy tearing and deformation of thin materials. It can adapt to harsh working conditions including high and low temperatures, humidity, salt spray, oil contamination and vibration.
Cost Reduction & Efficiency Improvement: The Spiral Press-In Stud eliminates nuts, washers and locking mechanisms, reducing the variety of materials and inventory pressure. No investment in welding equipment, no grinding processes and no rework costs are required, with assembly man-hours reduced by more than 60%. The permanent and reliable connection greatly lowers the risks of after-sales maintenance, on-site rework and end-product recalls.
Product Details Display
Spiral Knurl Details
The knurl texture of the Spiral Knurl Clinch Pin is continuous and uniform, with full tooth profiles, no collapsed corners, and no burrs. After press-fitting, it forms a 360° uniform engagement with the sheet metal, delivering stable torsion resistance and pull-out resistance. The knurl depth is optimized to ensure smooth insertion without tearing the plate material.
End Guidance and Positioning
The end of the Twist Knurl Press-In Stud adopts a precision guiding structure, enabling automatic centering and easy hole insertion, reducing the risk of assembly jamming. The positioning surface is flat and flush with the plate surface after press-fitting, with no height difference or tilt, ensuring smooth subsequent assembly.
Dimensional Accuracy Control
The outer diameter, length, knurled outer diameter, and head dimensions of the Spiral Groove Press Rivet Pin are strictly controlled within tolerance ranges, featuring high batch consistency. It is suitable for feeding and press-fitting on automated equipment without manual sorting, improving production line efficiency.
Surface and Appearance
The surface finish of the Twisted Knurl Clinch Insert is uniform with no color difference, missing plating, scratches, or oil contamination, presenting a clean and consistent appearance. Flatness, perpendicularity, and coaxiality meet the standards of precision fasteners, satisfying both the appearance and performance requirements of high-end equipment.
