Key Features & Benefits at a Glance
- Exceptional thermal stability maintains structural integrity from -60°F to 500°F, ideal for extreme temperature environments
- Superior chemical resistance of PEEK plastic prevents degradation from harsh industrial chemicals and solvents
- Reliable fastening performance with Class 2A thread fit ensuring consistent engagement and vibration resistance
- Optimized drive efficiency through No. 3 Phillips head design for secure installation and reduced cam-out risk
- Full threading coverage along the 3/4" length provides maximum grip strength and load distribution
- Regulatory compliance assurance with RoHS 3 and REACH standards for global industrial applications
- Lightweight corrosion-proof solution that eliminates galvanic corrosion concerns in mixed-material assemblies
Professional Applications & Engineering Value
These PEEK plastic rounded head screws deliver critical performance in demanding industrial settings where metal fasteners fail. The high-temperature resistance up to 500°F makes them ideal for thermal processing equipment, aerospace components, and automotive under-hood applications. Their chemical inertness prevents degradation in chemical processing plants, semiconductor manufacturing, and medical device assemblies. The UNC coarse thread pattern with Class 2A fit ensures rapid installation and reliable performance in vibration-prone environments, while the Phillips pan head design provides flush mounting with excellent torque transmission. These fully threaded screws maintain consistent clamping force across the entire 3/4" length, distributing stress evenly for enhanced joint durability.
Specification Summary & Compliance
Manufactured to ASME B18.6.3 specifications with Class 2A thread fit tolerance for precise engagement. Features 1/4"-20 UNC coarse threads with standard rounded pan head profile and No. 3 Phillips drive. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations. The 0.49" head diameter and 0.175" head height provide optimal bearing surface while maintaining low-profile installation.
