Push-In Clinching Screw
Products Description
Push-In Clinching Screws are fasteners that create a secure mounting point on thin metal sheets through cold extrusion and material embedding.
Their features include:
No welding, no tapping, and no additional nuts required.
Fast installation, stable locking, and strong vibration resistance.
Suitable for thin sheet metals (such as steel, stainless steel, and aluminum).
Essentially, the special "press-in toothed ring" structure on the screw head engages with the sheet metal during press-fitting, making it a stable fixing point integrated with the base material.
This makes Self-Clinching Screws widely used in structural components in various industries such as electronic device housings, automotive electronics, battery boxes, communication equipment, and rail transportation.
Main Functions: Focusing on the Core Needs of Tap-Free Fastening
Tapping-Free Rapid Fastening
No pre-tapping or drilling is required (some thin substrates can be directly penetrated). Assembly is completed with a single click using a riveting tool, significantly shortening mass production cycles and reducing labor and equipment costs. Suitable for large-scale automated assembly scenarios.
01
Permanent Self-Locking Connection
The plastic deformation of the substrate and the deep engagement of the Self-Clinching Bolt teeth form an irreversible, permanent connection. Pull-out resistance and shear strength are superior to traditional threaded screws. There is no risk of loosening under vibration and impact conditions, ensuring long-term product reliability.
02
Low Damage Protection to Substrate
The riveting process involves controllable plastic deformation, resulting in no chips or cracks. This avoids the structural damage to soft/thin substrates caused by traditional tapping, making Clinching Screw particularly suitable for fastening easily damaged workpieces such as aluminum shells, plastic parts, and thin steel plates.
03
Small-Free Clean Assembly
No chips are generated throughout the process, maintaining a clean assembly environment. No additional cleaning procedures are required, making Self-Clinching Compression Screw suitable for scenarios with high cleanliness requirements, such as electronic equipment and medical devices.
04
Multi-scenario adaptable fastening
Compatible with substrates of different thicknesses (0.5-3mm) and materials (aluminum, steel, plastic, composite materials), it can be used for various assembly forms, such as planar fastening and stacked connections to meet diverse engineering needs.

Product Nature and Core Features: A Novel "Sheet Metal Integration" Concept
| Cold Press Forming, No Damage to the Substrate | The entire press-fit process is completed at room temperature. Pressure causes the metal around the Self-Clinching Threaded Fastener to plastically flow, filling the specific annular groove (or embossing) at the bottom of the screw. This process is spark-free, smoke-free, and heat-affected zone-free, perfectly preserving the original metallographic structure and mechanical properties of the sheet metal, fundamentally avoiding the strength weakening risk associated with welding. |
| Permanent Anti-Rotation Design | The precision embossing (such as annular grooves, straight lines, and diamond patterns) beneath the Self-Clinching Screw is the embodiment of its core technology. During press-fitting, the sheet metal is squeezed into these patterns, forming a strong mechanical interlock. Once press-fitting is complete, the screw is integrated with the sheet metal, eliminating any possibility of rotation or loosening, providing torque retention capabilities far exceeding those of traditional nuts. |
| High-precision pre-formed threads | The threads are formed through a precision rolling process before riveting, resulting in precision, strength, and surface finish far exceeding those of machined threads. This means you don't get a hole to be machined, but a ready-to-use, high-quality threaded interface that meets industry standards. |
