S-99091A251 10-24 x 1 1/2" Plastic Hex Head Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance for long-lasting performance in harsh environments without rust or degradation
• Excellent electrical insulation properties to prevent short circuits and enhance safety in electrical assemblies
• Wide operating temperature range from -40°F to 185°F, ensuring reliability in both cold and moderately hot conditions
• Secure external hex drive design for easy installation with standard tools and reduced risk of stripping
• Precise Class 2A thread fit for consistent engagement and reliable fastening in industrial applications
• RoHS 3 compliance for environmentally safe use, meeting strict international regulatory standards
• Lightweight nylon construction that reduces overall assembly weight while maintaining durability

Professional Applications & Engineering Value

This 10-24 UNC coarse thread nylon hex head screw is engineered to address common industrial challenges such as corrosion and electrical conductivity risks. Made from durable black nylon plastic, it provides inherent resistance to moisture, chemicals, and galvanic corrosion, making it ideal for outdoor equipment, marine components, and chemical processing units. The fully threaded design and Class 2A fit ensure uniform load distribution and secure fastening in assemblies requiring vibration resistance. Its external hex drive allows for high-torque installation with common wrenches, speeding up assembly lines while the electrical insulation properties prevent current leakage in electronic enclosures and control panels. Suitable for HVAC systems, automotive interiors, and consumer electronics where non-conductive, temperature-stable fasteners are critical.

Specification Summary & Compliance

This screw adheres to UNC coarse thread standards with a Class 2A thread fit for consistent dimensional accuracy. Manufactured in the inch system, it features a 10-24 thread size, 1-1/2" length, and right-hand threading. The product is fully compliant with RoHS 3 (2015/863/EU) regulations, ensuring it is free from hazardous substances. No specific hardness rating is provided, as nylon's mechanical properties are optimized for corrosion resistance and insulation rather than extreme load-bearing.
