Key Features & Benefits at a Glance
- Superior corrosion resistance from durable nylon plastic construction, eliminating rust and chemical degradation in harsh environments
- Excellent electrical insulation properties for safe, reliable performance in electrical assemblies and sensitive applications
- Wide temperature tolerance (-40° to 185°F) maintains structural integrity and performance across extreme operating conditions
- Precision Class 2A thread fit with UNC coarse threading ensures secure, vibration-resistant fastening in various materials
- Undercut flat head design with 82° countersink angle provides flush mounting and reduced risk of head protrusion
- Full threading along 1 3/4" length delivers maximum grip strength and adjustment flexibility in assembly applications
- Industry compliance assurance with ASME B18.6.3 specifications and RoHS 3 environmental standards for quality and safety
Professional Applications & Engineering Value
These nylon plastic flat head screws deliver critical engineering solutions where metal fasteners fail. The non-conductive properties make them ideal for electrical enclosures, control panels, and electronic assemblies where electrical insulation is paramount. Their inherent corrosion resistance eliminates galvanic corrosion concerns in marine, chemical processing, and outdoor applications. The UNC coarse thread configuration provides excellent holding power in plastic, wood, and soft materials, while the 82° countersink angle and undercut head design ensure clean, flush installations that won't interfere with moving components. Operating reliably across extreme temperature ranges from -40° to 185°F, these screws maintain dimensional stability where thermal expansion would compromise metal alternatives.
Specification Summary & Compliance
Manufactured to precise Class 2A thread fit tolerances with UNC coarse threading (1/4"-20) and full threading along the 1 3/4" length. Features an 82° countersink angle with undercut flat head profile for optimal seating. Compliant with ASME B18.6.3 mechanical specifications and RoHS 3 (2015/863/EU) environmental directives, ensuring both performance reliability and regulatory compliance for industrial applications.
