Professional Applications & Engineering Value
These PEEK plastic screws deliver critical performance advantages in demanding industrial environments where metal fasteners fail. The high-temperature resistance (-60° to 500°F) makes them ideal for thermal cycling applications in aerospace, automotive, and electronics manufacturing. The fully threaded UNC coarse thread design with Class 2A fit provides superior holding power in plastic components and assemblies, while the Phillips drive system ensures efficient installation without specialized tools. As chemical-resistant fasteners, they withstand exposure to harsh solvents, fuels, and cleaning agents, eliminating corrosion concerns that plague metal alternatives. The rounded pan head profile distributes clamping force evenly, preventing stress concentration in delicate plastic housings and enclosures.
Specification Summary & Compliance
These 2-56 UNC screws feature precise Class 2A thread fit tolerances and are manufactured to ASME B18.6.3 specifications for dimensional consistency. The coarse thread spacing and fully threaded design provide optimal engagement in various materials. Compliance includes RoHS 3 (2015/863/EU) for hazardous substance restriction and REACH (EC 1907/2006) for chemical safety, ensuring suitability for regulated industries and international markets.
