Professional Applications & Engineering Value

These PEEK plastic rounded head screws deliver critical performance advantages in demanding industrial environments where metal fasteners fail. The high-temperature PEEK material maintains structural integrity from cryogenic conditions to 500°F, solving thermal expansion mismatch issues common in multi-material assemblies. The 4-40 UNC coarse thread configuration ensures rapid installation and reliable holding power in plastic and soft material applications, while the chemical-resistant properties prevent degradation from oils, solvents, and cleaning agents. The pan head profile with Phillips drive provides a low-profile solution for space-constrained applications requiring frequent maintenance access. These fully threaded screws are particularly valuable in electronics enclosures, medical devices, aerospace components, and chemical processing equipment where non-conductive, corrosion-resistant fasteners are essential.

Specification Summary & Compliance

These rounded head screws feature precise Class 2A thread fit per UNC standards with 4-40 coarse threading and right-hand thread direction. Manufacturing complies with ASME B18.6.3 specifications ensuring dimensional accuracy for head diameter (0.21"), head height (0.08"), and overall length (3/4"). The components are fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, making them suitable for global industrial applications requiring environmental responsibility.
