S-91627A113 3/4"-10 Flange Nuts

Key Features & Benefits at a Glance

• Exceptional load distribution with 1 1/2" flange diameter prevents surface damage and maintains joint integrity under high stress
• Superior corrosion resistance through zinc yellow-chromate plating protects against rust in harsh industrial environments
• Maximum strength reliability with Grade 8 classification ensuring consistent performance in heavy-duty applications
• Optimized thread engagement through UNC coarse threads with Class 2B fit for faster assembly and vibration resistance
• Enhanced installation efficiency with standard external hex drive allowing conventional tool compatibility
• Durable material construction using plated steel for long-term structural integrity in demanding conditions
• Reduced maintenance requirements through integrated flange design eliminating need for separate washers

Professional Applications & Engineering Value

This Grade 8 flange nut delivers critical engineering solutions where vibration resistance and structural integrity are paramount. The zinc yellow-chromate plated steel construction provides superior corrosion protection for outdoor equipment, agricultural machinery, and construction applications exposed to weather elements. The integrated 1 1/2" flange distributes clamping force effectively across wider surfaces, preventing material deformation in soft substrates while eliminating the need for additional washers. With 3/4"-10 UNC coarse threads and Class 2B thread fit, this heavy-duty fastener ensures reliable performance in high-vibration environments where fine threads might loosen, making it ideal for automotive suspensions, industrial machinery, and structural steel connections requiring exceptional strength and long-term reliability.

Specification Summary & Compliance

Manufactured to precise dimensional standards with Class 2B thread fit ensuring consistent engagement with mating components. The UNC coarse thread profile (3/4"-10) complies with ASME B18.2.2 specifications, while the Grade 8 strength classification meets ASTM A563 requirements for heavy-duty applications. The zinc yellow-chromate plating provides RoHS-compliant corrosion protection, and the external hex drive design accommodates standard wrenching tools for simplified installation across industrial maintenance and manufacturing operations.
