Professional Applications & Engineering Value
This 3/8"-16 UNC hex headless set screw delivers critical engineering solutions for industrial applications requiring secure component positioning. The 18-8 stainless steel composition provides excellent corrosion resistance, making it ideal for machinery exposed to moisture, chemicals, or outdoor elements. The Class 3A thread fit ensures precise engagement with mating components, eliminating play and maintaining alignment in high-vibration environments. The hex drive style allows for high torque application without slippage, while the flat tip design prevents damage to shaft surfaces. These set screws are particularly valuable in power transmission systems, coupling assemblies, and precision equipment where reliable locking is essential for operational safety and reduced maintenance intervals.
Specification Summary & Compliance
This set screw features 3/8"-16 UNC coarse threading with Class 3A thread fit for superior dimensional accuracy. The fastener measures 1/2" in length with a 0.375" thread diameter and right-hand thread direction. Manufacturing complies with ASME B18.3 specifications and meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental compliance standards, ensuring suitability for regulated industrial applications worldwide.
