S-95065A107 7/16"-20 Locknuts

Key Features & Benefits at a Glance

• Superior vibration resistance through precision distorted top threads that maintain secure fastening under extreme conditions
• Enhanced corrosion protection with zinc-plated steel construction for extended service life in harsh environments
• Reliable heavy-duty performance meeting Grade 5 strength standards for demanding industrial applications
• Precision thread engagement with Class 2B fit UNF fine threads ensuring consistent clamping force
• Easy installation and removal using standard external hex drive compatible with common wrench tools
• Environmental compliance with RoHS 3 and REACH regulations for sustainable manufacturing practices
• Optimized locking performance through top-lock distorted thread design that resists loosening under dynamic loads

Professional Applications & Engineering Value

This Grade 5 zinc-plated steel locknut delivers critical vibration resistance in high-stress assemblies where fastener integrity is paramount. The distorted top thread locking mechanism creates permanent friction that counters rotational forces in machinery, automotive, and heavy equipment applications. Engineered with UNF fine threads and Class 2B fit, this external hex locknut provides precise thread engagement that maintains clamping force while accommodating thermal expansion and contraction cycles. The zinc-plated surface treatment offers sacrificial protection against corrosion, extending service life in outdoor or chemically aggressive environments. This combination of mechanical locking performance and environmental durability makes it ideal for critical joints in construction equipment, transportation systems, and industrial machinery where safety and reliability cannot be compromised.
