- High durability and deformation resistance provided by Rockwell B55 hardness for long service life under load.
- Easy and secure installation with standard tools thanks to the 5/32" hex drive, preventing cam-out and head stripping.
- Effective surface grip and minimal part damage from the cup tip design, ideal for precise positioning on shafts and collars.
- Reliable performance in automated assembly with right-hand coarse (UNC) threads for quick installation and high tensile strength.
- Guaranteed quality and material safety through compliance with ASME B18.3, RoHS 3, and REACH standards.
Professional Applications & Engineering Value
This brass set screw is engineered to solve critical challenges in precision machinery and electrical applications where corrosion resistance and non-magnetic properties are paramount. The Class 3A thread fit and coarse UNC threads provide superior resistance to loosening under vibration, making it ideal for securing gears, pulleys, and knobs on rotating shafts. The headless design with a cup tip ensures a flush finish and concentrated holding force, preventing slippage and damage to expensive components. Its compliance with RoHS 3 and REACH makes it safe for use in sensitive industries, offering reliable performance in industrial assembly while meeting stringent engineering specifications for material integrity and environmental safety.
Specification Summary & Compliance
This set screw adheres to a Class 3A thread fit for high precision and strength, with UNC coarse threads (5/16"-18) and a right-hand direction. Manufacturing and dimensional standards strictly follow ASME B18.3. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006), ensuring it is free from hazardous substances and suitable for global industrial and electronic applications.
