Professional Applications & Engineering Value
This 1/4"-28 UNF Class 3A set screw is engineered to solve critical challenges in precision assembly and motion control systems. The combination of 18-8 stainless steel and a fine thread profile provides excellent resistance to loosening under vibration, a common failure point in machinery and automotive components. The headless, hex drive design allows for a flush fit in pulleys, gears, and collars, maximizing space efficiency while the flat tip offers superior surface contact for precise axial positioning without damaging the shaft. Its corrosion-resistant properties make it a reliable choice for food processing, marine, and chemical handling equipment, ensuring long-term performance and reducing maintenance downtime.
Specification Summary & Compliance
This set screw features a 1/4"-28 UNF thread with a precision Class 3A thread fit and a total length of 3/8". It is manufactured in strict accordance with the ASME B18.3 specification. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it meets the latest environmental and safety standards for industrial use.
