Professional Applications & Engineering Value
This 1/4"-20 UNC set screw is engineered to address critical challenges in industrial assembly, such as component slippage and misalignment under stress. The black oxide alloy steel construction provides excellent resistance to rust and wear, making it suitable for machinery, automotive, and manufacturing equipment where exposure to oils and moisture is common. The hex socket drive and headless design allow for easy installation in tight spaces, while the extended tip enhances contact and clamping force, reducing the risk of loosening due to vibrations. With a coarse thread and right-hand direction, it ensures quick fastening and reliable performance in high-load scenarios, supporting efficient maintenance and production workflows.
Specification Summary & Compliance
This set screw adheres to precise dimensional standards, including a Class 3A thread fit for tight tolerances and consistent performance. It conforms to ASME B18.3 specifications, ensuring reliability in mechanical applications. The product is compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006), supporting environmentally responsible sourcing and use in global markets.
