Professional Applications & Engineering Value
This 1/4"-20 pan head Phillips screw delivers critical engineering advantages for industrial assembly operations. The passivated 18-8 stainless steel construction provides exceptional corrosion resistance, making it suitable for manufacturing equipment, outdoor machinery, and chemical processing applications where environmental exposure is a concern. The coarse UNC threading combined with Class 2A thread fit ensures rapid installation while maintaining secure fastening in vibration-prone environments. The fully threaded design along the entire 1-5/8" length distributes clamping forces evenly, preventing material deformation in sheet metal, plastic components, and structural assemblies. The standard pan head profile with Phillips No. 3 drive offers compatibility with common industrial tools, streamlining production workflows.
Specification Summary & Compliance
This pan head screw features precise 1/4"-20 UNC coarse threads with Class 2A thread fit tolerance for consistent performance. Manufactured to ASME B18.6.3 specifications, it ensures dimensional accuracy and interchangeability. The fastener is fully compliant with RoHS 3 (2015/863/EU) restrictions on hazardous substances and REACH (EC 1907/2006) regulations for chemical safety. With right-hand threading and fully threaded construction, it maintains 70,000 psi tensile strength throughout its length for reliable industrial fastening applications.
