Professional Applications & Engineering Value
This 3/8"-16 UNC set screw is engineered to address critical challenges in industrial assembly and machinery. The black oxide alloy steel construction offers excellent resistance to rust and wear, making it suitable for environments exposed to moisture and friction. Its headless design with an extended tip provides a flush fit, essential for applications where protruding components are not feasible, such as in precision shaft collars, gears, and pulleys. The coarse UNC threads and Class 3A fit ensure a robust grip, minimizing the risk of loosening under high-vibration conditions common in heavy machinery and automotive systems. This combination of material strength and precise thread form delivers reliable, long-term performance, reducing maintenance needs and downtime in B2B industrial settings.
Specification Summary & Compliance
This set screw adheres to Class 3A thread fit for high precision and UNC coarse thread standards. It is manufactured in compliance with ASME B18.3 specifications and meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safety and sustainability in industrial use.
