- Wide temperature tolerance (-40° to 185°F) ensures reliable performance across diverse operating conditions
- Precision Class 2A thread fit with UNC coarse threading provides secure fastening and easy installation
- Standard 100° countersink angle delivers flush mounting for clean, professional finishes
- Full threading design maximizes grip strength and load distribution across the entire fastener length
- Compliance with ASME B18.6.3 and RoHS 3 guarantees quality standards and environmental safety
Professional Applications & Engineering Value
These nylon plastic flat head screws with 1/4"-20 UNC coarse threading solve critical engineering challenges where metal fasteners fail. The non-conductive properties prevent electrical shorts in control panels and electronic enclosures, while the inherent corrosion resistance makes them ideal for chemical processing, marine, and food-grade applications. The standard 100° countersink ensures seamless integration into angled surfaces without protrusion, and the full threading provides superior holding power in plastic and soft materials. These industrial plastic screws maintain dimensional stability across the -40° to 185°F temperature range, ensuring reliable performance in thermal cycling environments where metal expansion would compromise joint integrity.
Specification Summary & Compliance
Manufactured to ASME B18.6.3 specifications with Class 2A thread fit for consistent dimensional accuracy. Features UNC coarse threads (1/4"-20) in right-hand direction with standard flat head profile and slotted drive. Compliant with RoHS 3 (2015/863/EU) environmental regulations, containing no restricted hazardous substances. Suitable for applications requiring inch system measurements with full threading and 100° countersink angle.
