Professional Applications & Engineering Value
This 3/8"-16 UNC set screw delivers exceptional engineering value for industrial applications requiring precision and reliability. The 18-8 stainless steel construction provides excellent corrosion resistance, making it ideal for machinery, automotive components, and equipment exposed to moisture or chemicals. The hex headless design with Class 3A thread fit ensures maximum clamping force and vibration resistance, preventing component slippage in high-stress environments. The extended tip configuration allows for deeper penetration into mating parts, creating a more secure connection that withstands rotational forces. These industrial set screws are engineered to solve common fastening challenges in power transmission systems, shaft collars, and precision assemblies where reliability is critical.
Specification Summary & Compliance
This set screw features precision 3/8"-16 UNC coarse threading with Class 3A thread fit for superior dimensional accuracy. The extended tip maintains tight tolerances with tip diameter of 0.25" (-0.009" to 0") and tip length of 0.099" (-0.005" to 0"). Manufactured to ASME B18.3 specifications with full compliance to RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring both mechanical excellence and environmental responsibility.
