Professional Applications & Engineering Value
These PTFE plastic rounded head screws deliver critical performance advantages in demanding industrial environments where metal fasteners fail. The 4-40 UNC coarse thread configuration combined with Class 2A thread fit ensures reliable engagement in plastic components and soft materials while resisting vibration loosening. The fully threaded design provides maximum holding power across the entire 1" length, making them ideal for electronics enclosures, chemical processing equipment, food machinery, and laboratory instruments where chemical resistance and extreme temperature tolerance are essential. The white PTFE construction offers excellent dielectric properties for electrical applications while maintaining dimensional stability across the entire service temperature range.
Specification Summary & Compliance
This 4-40 UNC threaded screw features precise Class 2A thread fit tolerances with coarse thread spacing and fully threaded design. Manufacturing complies with ASME B18.6.3 standards for dimensional consistency and mechanical performance. The product meets RoHS 3 (2015/863/EU) compliance requirements and is REACH (EC 1907/2006) compliant for hazardous substances, ensuring suitability for regulated industrial applications and international markets.
