S-99051A900 1/4"-20 Press-Fit Nuts

Key Features & Benefits at a Glance

• Corrosion-resistant performance with 18-8 stainless steel construction for long-lasting reliability in harsh environments
• Secure press-fit installation ensures permanent retention without requiring secondary fastening operations
• Precision Class 2B thread fit provides consistent mating with mating components for reliable assembly
• RoHS 3 compliance meets international environmental standards for restricted substances
• Optimized for thin panel applications with 0.054" minimum thickness support for space-constrained designs
• Simplified installation process using standard 33/64" drill bit for quick, tool-compatible assembly
• Robust round head design with 0.6" OD distributes installation forces evenly across panel surfaces

Professional Applications & Engineering Value

This 1/4"-20 UNC press fit nut delivers exceptional value in electronic enclosures, control panels, and machinery guards where reliable threaded connections are critical. The 18-8 stainless steel construction provides superior corrosion resistance compared to carbon steel alternatives, making it ideal for applications exposed to moisture, chemicals, or outdoor conditions. The press-fit design eliminates the need for welding, tapping, or adhesives, significantly reducing assembly time and labor costs. With its coarse thread spacing and right-hand thread direction, this nut offers quick installation and removal while maintaining secure fastening in vibration-prone environments. The round head shape and precise dimensions ensure uniform pressure distribution during installation, preventing panel deformation and ensuring consistent performance across production runs.

Specification Summary & Compliance

This press-fit nut features 1/4"-20 UNC thread with Class 2B thread fit tolerance for precise mating with standard male threads. The component complies with RoHS 3 (2015/863/EU) environmental standards, ensuring freedom from restricted hazardous substances. Manufacturing specifications include 0.21" head height and 0.6" head outer diameter with compatibility for 33/64" (0.5156") drill bit size. Designed for installation in panels with minimum 0.054" thickness, this fastener meets industry standards for press-fit hardware in commercial and industrial applications.
