FH Carbon Steel Press Screws Standard Sheet Metal Clinch Fasteners
FH Carbon Steel Press Screws Standard Sheet Metal Clinching Fasteners
FH carbon steel clinch screws are the most widely used standard fasteners for sheet metal processing. Made of high-quality free-cutting carbon steel with knurled body, they are firmly embedded into thin metal sheets via press machine, delivering stable and permanent fastening for cabinet and electrical equipment assembly.
Clinching Principle
After inserting the screw into pre-punched holes, press force enables the knurled texture to embed into sheet metal. The plastic deformation of metal wraps the screw tightly, forming an integrated structure with excellent pull-out and torsion resistance.
Key Advantages
- Permanent integrated connection against falling off and loosening
- Standard precise threads compatible with regular nuts
- Galvanized anti-rust treatment for indoor environmental adaptability
- Suitable for thin sheet metal above 0.8mm thickness
- High consistency and interchangeability for mass production
Main Specifications
- Metric thread sizes: M3, M4, M5, M6 mainstream sizes
- Length range from 6mm to 50mm for diverse assembly demands
- Surface finishes: zinc plated, nickel plated optional
- Standard straight knurl design for universal sheet metal use
Application Scenarios
- Industrial chassis, cabinet and server shell assembly
- Home appliance and smart equipment sheet metal fixing
- Industrial control bracket and equipment panel fastening
- Communication and weak current equipment internal structure
