- Optimized head design with rounded pan profile for smooth surface contact and reduced risk of damage to sensitive materials
Professional Applications & Engineering Value
These PEEK plastic rounded head screws deliver critical performance in industries where metal fasteners fail, such as semiconductor manufacturing, aerospace, and medical equipment. The fully threaded 4-40 UNC coarse thread design ensures maximum grip in plastic and composite assemblies, while the high-temperature resistance prevents deformation under thermal cycling. Engineers specify these Phillips drive screws for their excellent dielectric properties and compliance with ASME B18.6.3, making them ideal for electrical enclosures, fluid handling systems, and cleanroom applications where corrosion, weight, and contamination are primary concerns.
Specification Summary & Compliance
This 1" length screw features Class 2A thread fit per UNC standards, ensuring precise dimensional accuracy and interchangeability. Manufactured in compliance with ASME B18.6.3 for consistent quality, and verified to meet RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations. The beige PEEK material provides consistent performance across the specified temperature range without additional coatings or treatments.
