S-93425A252 7/8"-9 Hex Nuts

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction, extending service life in harsh industrial environments
• Reliable left-hand thread engagement for specialized applications requiring reverse-threading security
• Optimized coarse thread design enabling faster assembly and reduced cross-threading risks
• Precise Class 2B thread fit ensuring consistent mating with UNC fasteners for vibration-resistant connections
• Heavy-duty Grade 2 strength rating providing dependable load distribution in structural applications
• Full regulatory compliance with RoHS 3 and REACH standards for global supply chain integration
• Standard external hex profile allowing high-torque installation with common wrench tools

Professional Applications & Engineering Value

This left-hand hex nut addresses critical reverse-threading requirements in rotating machinery, conveyor systems, and maintenance-sensitive equipment where standard right-hand threads would loosen under operational forces. The zinc-plated steel construction creates a sacrificial barrier against oxidation, while the UNC coarse thread profile maintains engagement integrity in high-vibration environments. Engineered with Class 2B thread fit tolerances, it ensures consistent mating with 7/8"-9 fasteners without galling or seizing. The external hex drive accommodates standard socket sets for efficient installation in confined spaces, making it ideal for assembly lines, heavy equipment, and infrastructure projects demanding left-hand thread reliability.

Specification Summary & Compliance

Manufactured to UNC coarse thread standards with Class 2B tolerance for consistent thread engagement. Dimensions include 7/8"-9 thread size, 1 5/16" width across flats, and 3/4" height. Complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, meeting Grade 2 mechanical properties for general purpose fastening applications.
