• Environmental compliance assurance with RoHS 3 (2015/863/EU) certification for regulated industrial applications

Professional Applications & Engineering Value

This nylon plastic hex head screw delivers critical engineering advantages where metal fasteners fail. The off-white nylon construction provides inherent corrosion resistance, making it ideal for chemical processing, marine, and outdoor applications where moisture and corrosive agents are present. The material's electrical insulation properties prevent current conduction, essential for electrical enclosures, control panels, and electronic assemblies. The 1/2"-13 UNC coarse thread with Class 2A thread fit ensures rapid installation in plastic, wood, and soft metal substrates while maintaining vibration resistance. The partial threading design concentrates thread engagement where needed most, reducing stress concentration and improving joint integrity. These features combine to solve common industrial challenges including galvanic corrosion, electrical hazards, and assembly inefficiency.

Specification Summary & Compliance

This 1/2"-13 UNC nylon hex head screw features Class 2A thread fit per ASME B1.1 standards, ensuring precise dimensional accuracy and interchangeability. The coarse thread spacing follows Unified National Coarse specifications with 1 1/4" minimum thread length on a 1 1/2" overall length. Manufacturing complies with RoHS 3 (2015/863/EU) environmental regulations, containing no restricted hazardous substances. The external hex drive and right-hand thread direction provide standard installation compatibility across industrial applications.
