Professional Applications & Engineering Value
This 1/4"-20 UNC steel set screw is engineered to address critical challenges in industrial assembly, such as component slippage and loosening under vibration. The cup point tip creates a strong indentation in the mating part, providing exceptional resistance to rotational forces and maintaining precise alignment in pulleys, gears, and collars. Manufactured from high-grade steel and heat-treated to a Rockwell B80 hardness, it withstands repetitive stress without deforming. The external square drive and square head allow for high-torque application with standard tools, reducing installation time and preventing stripping. Ideal for heavy machinery, automotive systems, and manufacturing equipment, this set screw ensures reliable performance where secure fastening is non-negotiable.
Specification Summary & Compliance
This set screw features a 1/4"-20 UNC coarse thread with Class 2A thread fit for standard dimensional accuracy and ease of assembly. It complies with ASME B18.6.2 manufacturing specifications, ensuring consistent quality and performance. Additionally, the product is RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, meeting stringent environmental and safety regulations for industrial use.
