S-91244A583 5/16"-18 x 1" Plastic Hex Head Screws

Key Features & Benefits at a Glance

• Corrosion-resistant nylon construction eliminates rust and chemical degradation in harsh environments
• Wide temperature tolerance (-40° to 185°F) maintains structural integrity across diverse operating conditions
• External hex drive design provides secure tool engagement and high torque capability
• Class 2A thread fit with UNC coarse threading ensures reliable assembly and vibration resistance
• RoHS 3 compliance meets stringent environmental regulations for industrial applications
• Non-conductive plastic material prevents electrical conductivity where isolation is critical
• Fully threaded shank delivers maximum grip length and uniform load distribution

Professional Applications & Engineering Value

These nylon hex head screws solve critical challenges in electrical, marine, and food processing applications where metal fasteners would corrode or conduct electricity. The off-white nylon plastic provides excellent chemical resistance against oils, solvents, and moisture while maintaining dimensional stability. With UNC coarse threading and Class 2A thread fit, these screws install quickly with standard tools and resist loosening under vibration. The external hex drive allows for high-torque installation without stripping, making them ideal for assembly lines and maintenance operations requiring repeated access. Their temperature resistance from -40° to 185°F ensures performance in both freezing outdoor and heated indoor environments.

Specification Summary & Compliance

Manufactured to precise dimensional standards with Class 2A thread fit and UNC coarse thread specifications (5/16"-18 thread size, 1" length). Features include right-hand threading, fully threaded design, and standard inch measurements. Compliant with RoHS 3 (2015/863/EU) environmental regulations, ensuring restriction of hazardous substances for industrial and commercial applications.
