Zinc-Plated Press Nuts Standard Rustproof Sheet Metal Clinch Nuts

Zinc-Plated Standard Press Nuts Universal Sheet Metal Clinch Fasteners

Zinc-plated clinch nuts are the most popular standard internal thread fasteners for sheet metal processing. Permanently fixed on thin metal plates via pressing process, they pre-set standard threads without manual tapping, greatly improving mass production efficiency with reliable anti-rust performance.

Clinching Principle

The outer knurled body embeds into pre-punched holes under pressure. Metal plastic deformation wraps the nut tightly, forming a permanent thread base with precise and reusable threads.

Key Advantages

• Pre-set threads save manual tapping working time
• Permanent embedded connection against loosening and falling
• Zinc plating provides stable indoor anti-rust protection
• Standard threads compatible with all regular screws
• Cost-effective for large-scale sheet metal mass production

Application Scenarios

• Thread prefabrication for industrial chassis and servers
• Home appliance and smart equipment sheet assembly
• Industrial control and automation equipment shell fixing
• Mass production of communication and weak current devices
• Standard thread point making for general sheet metal products
