Professional Applications & Engineering Value
This 1/4"-20 UNC hex headless set screw is engineered to address critical fastening challenges in machinery, automotive, and electronics assembly. Made from 18-8 stainless steel, it provides excellent resistance to rust and corrosion, ideal for environments exposed to moisture or chemicals. The Class 3A thread fit and coarse UNC thread ensure tight tolerances and easy alignment, reducing installation time and preventing thread damage. The cone point with 118° angle bites securely into shafts or collars, preventing slippage and maintaining positional accuracy under dynamic loads. Its headless design and 1/8" hex drive allow for flush mounting and access in tight spaces, making it a versatile solution for permanent or semi-permanent fastening needs in industrial equipment and precision instruments.
Specification Summary & Compliance
This set screw features a 1/4"-20 UNC coarse thread with Class 3A fit for precise dimensional accuracy, and a cone point with 118° angle. It meets ASME B18.3 specifications for consistent manufacturing quality. The product is RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, ensuring it adheres to environmental and safety regulations for hazardous substances.
