S-91835A721 8-32 Press-Fit Nuts

Key Features & Benefits at a Glance

• Vibration-resistant locking with nylon insert that maintains integrity up to 250°F, preventing loosening in high-stress environments
• Secure press-fit installation for panels as thin as 0.06", eliminating the need for welding or additional hardware
• Precision UNC coarse threading with Class 2B fit ensures smooth engagement and reliable fastening performance
• Durable steel construction with round flange design provides superior load distribution and long-term corrosion resistance
• Streamlined installation process using standard 7/32" drill bit (0.2188" diameter) reduces assembly time and labor costs
• Full regulatory compliance with RoHS 3 and REACH standards for safe use in global industrial applications
• Right-hand thread orientation enables intuitive installation and compatibility with standard 8-32 fastener systems

Professional Applications & Engineering Value

This 8-32 UNC press fit nut with nylon insert locking mechanism solves critical vibration-induced loosening problems in panel mounting applications across electronics enclosures, automotive assemblies, and industrial control systems. The steel construction combined with the round flange design (0.31" diameter) creates permanent mounting points in thin materials while distributing clamp load effectively. The coarse thread spacing and Class 2B thread fit ensure rapid installation without cross-threading risks, making it ideal for high-volume production environments. With its 250°F temperature rating, this locknut maintains performance in thermally challenging conditions where traditional fasteners would fail, providing engineers with a reliable solution for demanding industrial fastening requirements.

Specification Summary & Compliance

This press-fit locknut features 8-32 UNC coarse threads with Class 2B thread fit for precision engagement. The round flange measures 0.31" diameter with 0.16" head height, designed for minimum panel thickness of 0.06" using 7/32" (0.2188") drill bit. Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) standards, ensuring environmental responsibility and workplace safety. The right-hand thread direction and nylon insert locking mechanism meet industry standards for reliable performance in vibration-prone applications.
