Key Features & Benefits at a Glance
- Exceptional temperature resistance from -60° to 500°F ensures reliable performance in extreme thermal environments without degradation
- Superior chemical and corrosion resistance of PEEK plastic eliminates rust and maintains integrity in harsh industrial settings
- Precision Class 2A thread fit provides consistent engagement and vibration resistance in demanding assemblies
- Coarse UNC threading enables faster installation and reduced cross-threading risks in high-volume production
- Phillips drive design with rounded pan head offers secure tool engagement and low-profile installation
- Full threading along 3/16" length maximizes grip strength and load distribution across the entire fastener
- Comprehensive regulatory compliance including ASME B18.6.3, RoHS 3, and REACH ensures quality and environmental safety
Professional Applications & Engineering Value
These PEEK plastic rounded head screws deliver critical performance advantages in high-temperature industrial applications where metal fasteners would fail. The beige PEEK material maintains dimensional stability across extreme thermal cycles from -60° to 500°F, preventing loosening or failure in temperature-sensitive assemblies. The 4-40 UNC coarse thread configuration with Class 2A fit ensures reliable engagement in plastic and soft material components, while the Phillips drive system provides efficient installation in automated or manual assembly processes. These chemical-resistant fasteners are ideal for electronics enclosures, medical devices, aerospace components, and chemical processing equipment where corrosion resistance, electrical insulation, and thermal performance are paramount.
Specification Summary & Compliance
Manufactured to ASME B18.6.3 specifications with Class 2A thread fit tolerance for consistent performance. Features 4-40 UNC coarse threads with fully threaded 3/16" length and standard rounded pan head profile. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use in restricted substance applications.
