Key Features & Benefits at a Glance
- Superior corrosion resistance with zinc-plated steel construction, ensuring long-term reliability in harsh industrial environments
- Effortless installation with press-fit design that securely embeds into panels as thin as 0.056" without additional tools
- Exceptional thread durability provided by UNC coarse threading with Class 2B fit, maintaining secure connections under vibration
- Optimized panel compatibility with round head shape (0.25" OD, 0.07" height) that distributes load evenly across mounting surfaces
- Precision alignment using standard No. 19 drill bit (0.166" diameter) for consistent installation across production runs
- Right-hand thread direction for intuitive assembly that accelerates manufacturing processes
- Environmental compliance with RoHS 3 standards, meeting global regulatory requirements for industrial applications
Professional Applications & Engineering Value
Engineered for panel mounting applications in electronics enclosures, automotive assemblies, and industrial equipment, this zinc-plated steel press-fit nut solves critical fastening challenges. The UNC coarse thread design prevents cross-threading during assembly while maintaining Class 2B thread fit precision for repeated disassembly cycles. The round head press nut configuration distributes clamping force evenly across thin panels (minimum 0.056" thickness), eliminating deformation issues common in sheet metal applications. With right-hand threading and standardized installation parameters, manufacturers achieve consistent results in high-volume production environments while the zinc plating provides essential corrosion protection for extended service life in demanding conditions.
Specification Summary & Compliance
This press-fit nut maintains Class 2B thread fit tolerance per UNC standards with 4-40 thread size and coarse thread spacing. Manufactured to PEM® specifications for 0.056" minimum panel thickness using No. 19 drill bit (0.166" diameter). Full compliance with RoHS 3 (2015/863/EU) environmental directives and manufactured under quality systems meeting industrial fastening standards.
