S-94613A537 1/4"-20 x 1/2" Plastic Hex Head Screws

Key Features & Benefits at a Glance

• Corrosion-resistant nylon construction eliminates rust and galvanic corrosion in harsh environments, ensuring long-term reliability without metallic degradation.
• External hex drive with 3/8" head width provides secure, high-torque installation using standard tools, reducing slippage and assembly time.
• Class 2A UNC coarse threading delivers faster installation and superior vibration resistance in plastic and soft materials compared to fine threads.
• Wide temperature tolerance (-40° to 185°F) maintains structural integrity and performance across diverse industrial and outdoor settings.
• Fully threaded 1/2" length ensures maximum grip and uniform clamping force across the entire engagement area.
• RoHS 3 compliance guarantees environmental safety and regulatory adherence for global supply chains and sensitive applications.
• Off-white color and non-conductive properties prevent electrical conductivity and offer discreet, clean aesthetics in visible assemblies.

Professional Applications & Engineering Value

Engineered for demanding environments where metal fasteners fail, this nylon hex head screw solves critical challenges in electrical enclosures, marine hardware, and food processing equipment. Its inherent corrosion resistance eliminates galvanic reactions with dissimilar metals, while the UNC coarse thread design prevents stripping in soft substrates like plastic housings and composite panels. The external hex drive ensures reliable torque transmission without cam-out, and the temperature-stable nylon material retains mechanical properties from sub-zero conditions to near-boiling points. Ideal for RoHS-compliant assemblies, it provides electrical insulation and chemical inertness where conductivity or contamination risks exist.

Specification Summary & Compliance

This fastener adheres to UNC coarse thread standards with Class 2A thread fit for consistent engagement and interchangeability. Manufacturing complies with RoHS 3 (2015/863/EU) regulations, ensuring restricted substance-free composition. Dimensional accuracy includes 1/4"-20 thread size, 1/2" length, and fully threaded construction for uniform load distribution.
