• High-strength durability from Rockwell B80 hardness, providing reliable performance under heavy-duty mechanical stress
• Easy and secure installation with the hex drive design, allowing for high torque application without slippage
• Enhanced grip and positioning from the extended tip, which digs into materials for superior resistance to rotation and vibration
• Broad industrial compatibility with UNC coarse threads and right-hand direction, fitting standard applications for quick assembly
• Regulatory peace of mind with compliance to ASME B18.3, RoHS 3, and REACH, ensuring safety and environmental standards are met

Professional Applications & Engineering Value

This 3/8"-16 UNC set screw is engineered to address critical challenges in industrial assembly, such as component slippage and corrosion-induced failure. The 18-8 stainless steel material offers excellent resistance to rust and chemicals, making it suitable for applications in machinery, automotive, and outdoor equipment where exposure to moisture is common. The Class 3A thread fit and coarse thread spacing provide a precise, tight engagement that withstands high vibration and load, reducing maintenance needs. With its headless design and extended tip, it ensures a flush finish and deep penetration into shafts or collars, ideal for securing pulleys, gears, and other rotating parts without protruding elements. This combination of hex drive ease and robust thread standards delivers reliable performance in demanding engineering environments.
