- Compliance with RoHS 3 and REACH regulations ensures environmental safety and global supply chain compatibility
Professional Applications & Engineering Value
These 4-40 UNC coarse thread screws in A286 stainless steel are engineered to address common challenges in aerospace, automotive, and electronics manufacturing, where high tensile strength and thermal stability are critical. The flat head Torx design with T8 drive minimizes tool slippage, reducing assembly errors and maintenance downtime. The Class 3A thread fit and fully threaded construction ensure uniform stress distribution, preventing loosening under dynamic loads. With an 82° countersink, they provide a secure, low-profile finish, ideal for applications requiring smooth surfaces and reliable performance in harsh conditions.
Specification Summary & Compliance
This product adheres to UNC coarse thread standards with a Class 3A thread fit for precise dimensional accuracy. Manufactured from A286 stainless steel with a hardness of Rockwell C24, it meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, ensuring environmental and safety standards. The right-hand thread direction and inch system measurements support consistent performance in regulated industrial applications.
