Professional Applications & Engineering Value

This 10-24 UNC flat head screw is engineered from 18-8 stainless steel with a passivated finish to combat corrosion in challenging settings like marine, chemical processing, and outdoor equipment. The drilled spanner drive prevents cam-out, allowing for high-torque installation without damaging the head, which is crucial in maintenance and assembly lines. Its fully threaded design and Class 2A thread fit provide consistent clamping force, reducing loosening from vibrations. Ideal for applications requiring a flush surface—such as machinery panels, automotive components, and electronic enclosures—this screw ensures long-term reliability and meets stringent ASME B18.6.3 specifications for dimensional accuracy.

Specification Summary & Compliance

The screw features a 10-24 UNC coarse thread with Class 2A fit for precise tolerance, a head diameter of 0.362", and a length of 5/8". It conforms to ASME B18.6.3 manufacturing standards and is compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and material integrity.
