Professional Applications & Engineering Value

This hex headless set screw is engineered to address common industrial challenges like component slippage, vibration loosening, and corrosion in demanding environments. Manufactured from 18-8 Stainless Steel, it offers excellent resistance to rust and chemical exposure, making it suitable for machinery, automotive, and marine applications. The Class 3A UNF fine thread ensures a tight, secure fit that maintains clamping force under dynamic loads, while the 90° cone point bites into shafts and collars to prevent rotational movement. Its headless design allows for flush installation in confined spaces, providing a clean, professional finish. Ideal for securing gears, pulleys, and knobs, this set screw delivers reliable performance where precision and durability are critical.

Specification Summary & Compliance

This set screw features a 3/8"-24 UNF fine thread with Class 3A thread fit for high precision and minimal backlash. It complies with ASME B18.3 manufacturing standards, ensuring dimensional accuracy and interoperability. Environmental and safety adherence includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, confirming it is free of hazardous substances. The Rockwell B80 hardness and specified cone point angle further guarantee consistent performance in industrial fastening applications.
