S-97149A350 3/4"-10 Hex Nuts

Key Features & Benefits at a Glance

• Superior corrosion resistance from Black-Oxide 18-8 Stainless Steel, ideal for harsh environments and reducing maintenance costs.
• Reliable thread engagement with Class 2B thread fit, ensuring consistent clamping force and vibration resistance in heavy-duty assemblies.
• Quick installation and removal using standard external hex drive, compatible with common wrenches for efficient field service.
• Durable coarse thread design (3/4"-10 UNC) that resists cross-threading and handles high loads in structural and machinery applications.
• Environmental compliance assurance with RoHS 3 and REACH, meeting strict industrial regulations for safe, sustainable sourcing.
• Optimized strength-to-weight ratio from 18-8 stainless steel, providing robust performance without unnecessary bulk.
• Wide industrial compatibility due to UNC thread standards, simplifying replacements in North American equipment and fixtures.

Professional Applications & Engineering Value

Engineered for demanding environments, this 3/4"-10 UNC hex nut delivers critical reliability where failure is not an option. The Black-Oxide 18-8 Stainless Steel construction combats rust and chemical exposure in outdoor infrastructure, marine hardware, and food processing equipment, while the coarse thread profile maintains grip under dynamic stresses. Its Class 2B thread fit minimizes backlash in bolted joints, preventing loosening in vibrating machinery and transportation systems. By integrating external hex drive for tool accessibility, it streamlines maintenance in confined spaces, reducing downtime in assembly lines and construction projects. This nut is a go-to solution for engineers prioritizing longevity and regulatory adherence in industrial fasteners.

Specification Summary & Compliance

This hex nut adheres to UNC thread standards with a Class 2B thread fit for consistent dimensional accuracy. It meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, ensuring it is free of restricted substances. Manufacturing follows industry norms for inch-system coarse threads, with a width of 1 1/8" and height of 41/64" for uniform integration into existing assemblies.
