Professional Applications & Engineering Value

These 1/4-20 UNC thread cutting screws deliver exceptional engineering value by solving critical fastening challenges in brass, cast iron, and sheet metal applications. The 410 Stainless Steel composition provides inherent corrosion resistance, while the Type F thread cutting design eliminates the need for pre-tapped holes, significantly reducing installation time and labor costs. The coarse thread spacing ensures rapid installation and superior pull-out resistance, making these Phillips pan head screws ideal for high-volume production environments where reliability and efficiency are paramount. The combination of fully threaded construction and right-hand thread direction provides consistent clamping force across the entire fastener length, preventing material distortion in thin-section applications.

Specification Summary & Compliance

Manufactured to precise dimensional standards with UNC coarse thread spacing and Class 2A thread tolerances for consistent performance. The thread cutting Type F design follows industry-standard tapping screw specifications. Compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and unrestricted use in industrial markets. Standard pan head profile with 0.492" head diameter provides optimal bearing surface for secure fastening in various material thicknesses.
