- High-strength durability with a Rockwell B80 hardness, ensuring the set screw maintains its form under significant stress.
- Easy and secure installation with the 1/16" hex drive and headless design, allowing for flush mounting in tight spaces.
- Reliable performance in automated assembly due to the flat tip and right-hand thread, providing consistent seating and torque.
- Full compliance with major industry standards including ASME B18.3, ensuring interchangeability and engineering reliability.
- Environmentally safe for global supply chains as it is RoHS 3 and REACH compliant, meeting strict international regulations.
Professional Applications & Engineering Value
This 6-32 UNC Class 3A set screw is engineered to solve critical challenges in precision assembly and machinery. Manufactured from 18-8 stainless steel, it offers excellent resistance to corrosion and oxidation, making it suitable for applications in automotive, aerospace, and marine environments where moisture and chemicals are present. The coarse thread spacing and Class 3A thread fit provide a tighter tolerance, reducing the risk of loosening under vibration—a common pain point in dynamic systems. The hex headless drive and flat tip design allow for unobtrusive installation in confined spaces, ensuring components remain securely locked without protruding hardware. This combination of material strength and thread precision delivers reliable performance in collars, gears, and pulleys, enhancing the longevity and safety of industrial equipment.
Specification Summary & Compliance
This set screw adheres to precise dimensional standards with a UNC thread size of 6-32 and a Class 3A thread fit for high accuracy. It meets the ASME B18.3 specification for set screws, ensuring consistent quality and interchangeability. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming it is free from hazardous substances and safe for use in various international markets.
