S-93439A038 1"-8 Hex Nuts

Key Features & Benefits at a Glance

• Superior corrosion resistance for extended service life in marine and chemically aggressive environments
• Reliable coarse threading (1"-8 UNC) ensures quick assembly and reduced cross-threading risks
• Class 2B thread fit provides consistent engagement and vibration resistance with standard bolts
• External hex design offers high torque capability with common wrench tools
• Full RoHS 3 & REACH compliance meets stringent international environmental and safety standards
• Durable silicon bronze construction maintains mechanical strength under extreme moisture and temperature fluctuations
• Standard inch dimensions (1-1/2" width, 55/64" height) ensure compatibility with existing industrial equipment

Professional Applications & Engineering Value

Engineered for demanding applications where corrosion resistance is critical, these silicon bronze hex nuts solve fastener degradation problems in marine hardware, offshore platforms, and chemical processing equipment. The 1"-8 UNC coarse thread design maintains clamping force under vibration, while the external hex drive allows for high-torque installation in confined spaces. Unlike standard steel fasteners, the silicon bronze material provides inherent resistance to saltwater corrosion and stress cracking, making these nuts ideal for permanent installations in harsh environments where maintenance access is limited.

Specification Summary & Compliance

Manufactured to UNC thread standards with Class 2B thread fit tolerances for consistent mating with Class 2A bolts. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring restriction of hazardous substances. Dimensions: 1-1/2" width across flats, 55/64" height. Right-hand thread direction with coarse thread spacing suitable for general industrial applications.
