Professional Applications & Engineering Value

This 3/8"-16 UNC set screw is engineered to solve critical fastening challenges in demanding industrial settings. The 316 stainless steel material offers excellent resistance to corrosion and oxidation, making it suitable for applications in chemical processing, marine equipment, and food machinery where moisture and corrosive agents are present. The headless design with a hex socket drive allows for a flush finish, preventing protrusions and enabling use in confined spaces. The Class 3A thread fit ensures minimal backlash and superior vibration resistance, which is crucial for maintaining assembly integrity in high-stress environments like automotive components, machinery shafts, and precision tools. The extended tip provides improved contact and alignment, reducing the risk of slippage and enhancing the screw's holding capability in rotational assemblies.

Specification Summary & Compliance

This set screw adheres to precise dimensional standards, including a UNC coarse thread with a Class 3A fit for high accuracy and a 3/8"-16 thread size. The tip features an extended design with a diameter of 0.25" and controlled tolerances. Manufactured in compliance with ASME B18.3 specifications, it also meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulatory requirements, ensuring environmental safety and material reliability for industrial procurement.
