Professional Applications & Engineering Value
These 10-24 UNC flat head screws with zinc-plated steel construction provide exceptional value in industrial applications where corrosion resistance and high tensile strength are critical. The T20 Torx drive system ensures maximum torque transfer without stripping, making them ideal for assembly lines requiring repetitive fastening operations. The partially threaded design combined with Class 3A thread fit offers superior vibration resistance in machinery, automotive components, and electrical enclosures. The 82° countersink angle and flat head profile create seamless surface finishes while the coarse thread spacing enables quick installation in various substrates, reducing assembly time and labor costs in high-volume manufacturing environments.
Specification Summary & Compliance
Manufactured to precise dimensional standards with Class 3A thread fit tolerance for superior engagement. Complies with ASME B18.6.3 mechanical specifications and maintains RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental compliance. Features UNC coarse threading with right-hand direction and maintains consistent 60,000 psi tensile strength throughout the 2 1/2" length with partial threading extending to minimum 1 3/4" thread length.
