Key Features & Benefits at a Glance
- Corrosion-resistant 18-8 stainless steel ensures long-term durability in harsh industrial environments
- Precision Class 2B thread fit guarantees reliable, vibration-resistant connections in assembly operations
- Press-fit installation design eliminates need for welding or adhesives, reducing assembly time and labor costs
- Optimized round head geometry (0.44" OD × 0.17" height) provides maximum pull-out resistance in thin panels
- UNC coarse threading enables faster installation and reduced cross-threading risk in production environments
- Standard 11/32" drill bit compatibility simplifies panel preparation and maintains installation consistency
- RoHS 3 compliance meets international environmental regulations for electronics and electrical applications
Professional Applications & Engineering Value
This 18-8 stainless steel press-fit nut delivers exceptional value in electrical enclosures, control panels, and machinery assemblies where corrosion resistance and reliable thread performance are critical. The UNC coarse thread pattern combined with Class 2B fit ensures consistent engagement even in high-vibration applications, while the press-fit installation eliminates thermal distortion risks associated with welding. Engineered specifically for 0.056" minimum panel thickness, this fastener solves common challenges in thin-sheet metal applications where traditional nuts would require additional reinforcement. The round head design distributes installation forces evenly, preventing panel deformation during the pressing operation.
Specification Summary & Compliance
Manufactured to precise dimensional standards with 1/4"-20 UNC coarse threads maintaining Class 2B thread fit per ASME/ANSI specifications. The inch-system fastener features 0.44" head OD and 0.17" head height with right-hand thread direction. Complies with RoHS 3 (2015/863/EU) regulations and engineered for installation in panels using standard 11/32" (0.3438") drill bits as specified by PEM® engineering standards.
