S-91395A130 8-32 Hex Nuts

Key Features & Benefits at a Glance

• Superior thermal resistance maintains structural integrity in environments up to 190°F, preventing deformation under heat stress
• Excellent corrosion resistance from fiberglass construction ensures long service life in harsh industrial settings without rust or degradation
• Reliable coarse threading (UNC 8-32) provides faster installation and reduced cross-threading risk compared to fine-thread alternatives
• Precision Class 2B thread fit guarantees consistent engagement and vibration resistance in assembled components
• Standard external hex drive design enables high-torque installation using common wrench tools for efficient maintenance
• RoHS 3 compliance meets international environmental standards for hazardous substance restriction in manufacturing
• Right-hand threading convention ensures compatibility with standard industrial equipment and simplified replacement procedures

Professional Applications & Engineering Value

This fiberglass hex nut addresses critical challenges in high-temperature industrial applications where metal fasteners typically fail due to thermal expansion or galvanic corrosion. The gray fiberglass material provides inherent resistance to chemical exposure and electrical insulation properties, making it ideal for electrical enclosures, HVAC systems, and processing equipment. The coarse UNC 8-32 thread maintains secure fastening despite vibration or thermal cycling, while the standard hex profile ensures compatibility with existing maintenance protocols. Engineers specify this solution for applications requiring non-conductive, thermally stable fasteners that won't compromise system integrity under continuous operational stress.

Specification Summary & Compliance

Manufactured to Class 2B thread fit tolerances for consistent engagement with mating components. Complies with RoHS 3 (2015/863/EU) standards restricting hazardous substances. Thread specifications conform to Unified National Coarse (UNC) standards with 8-32 thread size and right-hand direction. Dimensions include 3/8" width across flats and 1/8" height for standardized installation. Maximum service temperature rated at 190°F for reliable performance in thermal applications.
