Professional Applications & Engineering Value
This 1/4"-28 UNF hex head screw is engineered to solve critical challenges in demanding industrial settings. The core value lies in its 316 Stainless Steel composition, which offers far greater resistance to chlorides and acidic conditions compared to standard grades, drastically reducing the risk of fastener failure in chemical processing, marine, or outdoor applications. The combination of a fine thread (UNF) and Class 2A fit provides superior vibration resistance and a tighter clamp force, making it an ideal choice for precision machinery, automotive assemblies, and electronic enclosures where loosening is not an option. The external hex drive and fully threaded design allow for high torque application and consistent engagement, ensuring a durable, long-lasting connection that maintains integrity under stress.
Specification Summary & Compliance
This screw adheres to precise dimensional standards, featuring a 1/4"-28 UNF thread with a Class 2A tolerance for consistent, reliable fit. The manufacturing and quality are governed by the ASME B18.2.1 specification. Furthermore, this product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it is free of restricted hazardous substances for safe use in global markets.
