The Penn Engineering 1430-1BM3 is a self-clinching fastener that creates permanent internal threads in thin metal sheets down to 0.030 inches. Installation is accomplished by squeezing the fastener into a pre-punched hole using controlled force, eliminating the need for welding, tapping, or secondary operations. This permanent fastening method delivers reliable thread engagement in applications where material thickness constrains traditional fastening approaches.
Technical Specifications
• Product Type: Self-clinching fastener
• Thread Type: Permanent internal threads
• Minimum Sheet Metal Thickness: 0.030 inches
• Installation Method: Squeeze into pre-punched hole using specialized tooling or press
• Material Compatibility: Metal sheets
• Corrosion Resistance: Determined by base material and plating selection
– Key Features
• Eliminates welding and tapping operations
• Provides permanent thread engagement without secondary processing
• Enables fastening in extremely thin sheet metal applications
• Requires precisely sized pre-punched hole for optimal performance
• Installation via controlled squeezing force deforms parent material around fastener body
• Fastener head positioned flush or slightly proud of sheet surface depending on type
– Typical Applications
• Electronic assemblies with space constraints
• Electrical enclosures and chassis
• Mechanical assemblies in thin-gauge materials
• Applications requiring permanent threaded holes without post-installation machining
– Compatibility & Integration
Successful installation demands hole preparation to exact specifications dictated by fastener geometry and parent material thickness. The clinching process creates a mechanical lock as the fastener deforms surrounding material, establishing permanent attachment without adhesives or welds. Press tooling must deliver controlled, consistent force to ensure complete clinching and full thread depth engagement.
