Professional Applications & Engineering Value
This 18-8 stainless steel hex head screw is engineered to address common industrial challenges such as corrosion, vibration loosening, and high-stress fatigue. The UNF fine thread configuration enhances joint integrity in machinery, automotive, and structural assemblies by maintaining clamp load under dynamic conditions. Its Rockwell B70 hardness and 80,000 PSI tensile strength provide durability against mechanical wear, making it suitable for heavy-duty applications. The fully threaded design ensures uniform stress distribution, reducing the risk of shear failure. Ideal for industrial fastening in corrosive environments, this screw delivers long-term reliability and minimizes maintenance downtime.
Specification Summary & Compliance
This fastener adheres to Class 2A thread fit tolerances for precise dimensional accuracy, with UNF fine thread specification (7/16"-20). It is manufactured to meet RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, ensuring it is free from hazardous substances. The screw features a right-hand thread direction and is fully threaded along its 2 1/2" length, providing consistent performance in accordance with industrial standards.
