Professional Applications & Engineering Value

These 1/4-20 UNC thread cutting screws deliver exceptional value in industrial fastening applications where material integrity and installation efficiency are critical. The 410 stainless steel composition provides excellent resistance to corrosion and wear, while the F-type tapping screw design with coarse UNC threads creates precise mating threads in brass, cast iron, and sheet metal substrates without requiring pre-tapped holes. The Phillips flat head configuration with 82° countersink angle ensures flush mounting for clean finishes and improved aerodynamics in assembled components. This combination of material strength and thread cutting capability significantly reduces installation time and labor costs while maintaining reliable, vibration-resistant connections in manufacturing, automotive, and metal fabrication applications.

Specification Summary & Compliance

Manufactured to precise dimensional standards with UNC coarse thread profile and Class 2A thread tolerances for consistent performance. These F-type tapping screws feature a standard flat head profile with 0.477" head diameter and 1" fully threaded length. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use across various industrial sectors. The right-hand thread direction and blunt tip design provide controlled engagement and prevent material damage during installation.
