Key Features & Benefits at a Glance
- Superior corrosion resistance for long-lasting performance in harsh chemical or moist environments where metal fasteners degrade
- Excellent electrical insulation properties prevent short circuits and current leakage in sensitive electrical assemblies
- Lightweight nylon construction reduces overall assembly weight without compromising mechanical integrity
- Wide operating temperature range from -40°F to 185°F maintains dimensional stability across various industrial conditions
- Standard 100° countersink angle ensures flush mounting with clean, professional finishes in panel and fixture applications
- Class 2A thread fit with UNC coarse threading provides reliable engagement and faster installation in plastic and soft materials
- Full threading along the 1/2" length maximizes grip strength and load distribution across the entire fastened joint
Professional Applications & Engineering Value
This nylon plastic flat head screw delivers critical engineering solutions where metal fasteners create operational risks. The non-conductive properties make it ideal for electrical enclosures, control panels, and electronic assemblies where stray currents could damage sensitive components. In corrosive environments—chemical processing, marine applications, or outdoor installations—the inherent corrosion resistance eliminates galvanic corrosion and contamination concerns. The standard 100° countersink angle and flat head design provide smooth, flush surfaces that won't snag wiring or interfere with moving parts. With UNC coarse threading and Class 2A fit, installation is quick and secure in plastic housings, composite materials, and soft substrates where fine threads might strip.
Specification Summary & Compliance
Manufactured to ASME B18.6.3 specifications with Class 2A thread fit tolerance for consistent engagement. Features 1/4"-20 UNC coarse threads with right-hand orientation and full threading along the 1/2" length. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations for restricted substance control. The standard 100° countersink angle ensures proper seating in matched countersunk holes.
