Professional Applications & Engineering Value
This 4-40 UNC set screw is engineered to address critical challenges in precision machinery, electronics, and automotive systems where vibration resistance and space constraints are paramount. The 316 Stainless Steel material offers exceptional resistance to chemicals and moisture, preventing failure in corrosive industrial environments. Its coarse UNC thread and Class 3A fit provide rapid assembly with high clamping force, reducing the risk of loosening under dynamic loads. The headless design and cup tip ensure a flush finish and concentrated point contact, making it ideal for securing collars, knobs, and shafts without protruding hardware. By meeting ASME B18.3 specifications, it delivers consistent quality for OEM and MRO applications, enhancing equipment durability and reducing maintenance cycles.
Specification Summary & Compliance
This set screw adheres to Class 3A thread tolerance for precise fit and UNC 4-40 thread specifications. It is manufactured in compliance with ASME B18.3 standards and is RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliant, ensuring environmental safety and regulatory adherence for global industrial use.
