Professional Applications & Engineering Value

These PTFE-coated stainless steel pan head screws are engineered to address critical challenges in industrial fastening, including corrosion, chemical exposure, and mechanical stress. The 18-8 stainless steel base provides inherent rust resistance, while the PTFE coating adds a non-stick, low-friction surface that prevents seizing and reduces maintenance downtime. With UNC coarse threading and Class 2A fit, these screws offer quick assembly and reliable holding power in equipment manufacturing, chemical processing, and marine applications. The fully threaded design ensures maximum grip across the entire length, making them ideal for securing panels, machinery components, and structural assemblies where vibration resistance and durability are paramount.

Specification Summary & Compliance

This screw features a 1/4"-20 UNC coarse thread with Class 2A tolerance for precise fit, and is manufactured to ASME B18.6.3 specifications. It complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it is free of hazardous substances. The Rockwell B70 hardness and 70,000 psi tensile strength confirm its reliability for industrial use.
