S-94140A107 10-32 Locknuts

Key Features & Benefits at a Glance

• Superior vibration resistance through innovative Flex-Top locking technology that maintains tension under dynamic loads
• Excellent corrosion protection with 18-8 Stainless Steel construction for extended service life in harsh environments
• Space-saving thin profile (3/16" height) ideal for applications with limited clearance while maintaining full locking performance
• Precise Class 2B thread fit ensures smooth installation and consistent clamping force throughout the fastener's lifespan
• Reliable fine threading (10-32 UNF) provides enhanced engagement and superior resistance to loosening compared to coarse threads
• Standard external hex drive allows for conventional tooling and familiar installation procedures across maintenance teams
• Full regulatory compliance with RoHS 3 and REACH standards for environmentally responsible manufacturing and global acceptance

Professional Applications & Engineering Value

This 10-32 UNF thin profile locknut addresses critical vibration-induced loosening challenges in industrial equipment, machinery, and precision assemblies. The Flex-Top locking mechanism creates consistent radial pressure along the thread engagement, effectively dampening harmonic vibrations that compromise standard fasteners. Manufactured from 18-8 Stainless Steel, this locknut maintains its anti-vibration properties while resisting corrosion from chemicals, moisture, and atmospheric exposure. The thin hex nut profile proves particularly valuable in compact electronic enclosures, instrumentation panels, and aerospace components where space optimization is paramount. With fine threading and Class 2B thread fit, installation torque remains predictable while achieving reliable preload in precision assemblies requiring repeated maintenance access.

Specification Summary & Compliance

This locknut features 10-32 UNF fine threads with Class 2B thread fit per ASME B1.1 standards, ensuring precise dimensional accuracy and consistent performance. The 3/8" across flats hex configuration and 3/16" height provide standardized tool engagement while maintaining the thin profile advantage. Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming the absence of restricted substances and supporting global environmental safety standards for industrial fastener applications.
