S-91078A210 5/16"-24 Hex Nuts

Key Features & Benefits at a Glance

• Enhanced corrosion resistance with zinc-plated steel construction for extended service life in demanding environments
• Space-saving thin profile (3/16" height) ideal for applications with limited clearance without compromising strength
• Secure, vibration-resistant assembly ensured by Class 2B thread fit and fine UNF 5/16"-24 threading
• Reliable Grade 2 strength providing consistent performance for general industrial fastening requirements
• Easy installation and removal with standard 1/2" external hex drive compatible with common tools
• Right-hand thread direction for standard assembly procedures and operator familiarity
• Full regulatory compliance with RoHS 3 and REACH standards for safe, environmentally responsible manufacturing

Professional Applications & Engineering Value

This 5/16"-24 UNF thin hex nut delivers critical engineering advantages where standard nuts prove too bulky. The zinc-plated steel construction provides essential corrosion protection for machinery, automotive components, and electrical enclosures exposed to moisture or industrial atmospheres. Its fine UNF threads and Class 2B thread fit create superior vibration resistance in precision assemblies, preventing loosening under dynamic loads. The reduced thin hex nut profile solves clearance challenges in compact designs while maintaining full Grade 2 strength integrity. These characteristics make it particularly valuable for OEM manufacturing, maintenance operations, and equipment where reliable, long-term fastening is paramount.
