Professional Applications & Engineering Value
This 3/8"-24 UNF Class 3A set screw is engineered to address critical challenges in industrial assembly and precision machinery. Made from 18-8 stainless steel, it resists corrosion and oxidation, making it suitable for applications exposed to moisture, chemicals, or outdoor conditions. The fine thread spacing and Class 3A thread fit provide a tighter tolerance, reducing the risk of loosening under vibration and ensuring consistent clamping force in dynamic environments. The headless design with a hex drive allows for flush mounting in confined spaces, while the cup tip offers excellent grip on shafts or collars without causing significant surface marring. Ideal for securing gears, pulleys, and other components in automotive, aerospace, and manufacturing equipment, this set screw delivers reliable performance where maximum holding power and long-term durability are paramount.
Specification Summary & Compliance
This set screw features a 3/8"-24 UNF fine thread with Class 3A thread fit for high precision and tight engagement. It complies with ASME B18.3 specifications for dimensional accuracy and performance. The product is also RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, ensuring it meets stringent environmental and safety regulations for hazardous substances.
