Professional Applications & Engineering Value
This 3-48 UNC set screw delivers exceptional engineering value in applications requiring precise component positioning and secure fastening. The black-oxide alloy steel construction provides a robust barrier against oxidation and wear, ideal for machinery, automotive, and electronics where environmental factors threaten fastener integrity. Its headless hex drive and cup tip design enable flush mounting and concentrated clamping force, solving common issues like loosening under vibration or misalignment in assemblies. With coarse thread spacing and Class 3A thread fit, it ensures quick installation and high fatigue resistance, reducing maintenance needs in production lines and industrial equipment.
Specification Summary & Compliance
This set screw adheres to inch system dimensions, including a 0.099" thread diameter, 1/16" length, and UNC thread type with Class 3A thread fit for superior precision. It meets ASME B18.3 and ASTM F912 manufacturing specifications, guaranteeing consistent quality and performance. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and material sustainability in global supply chains.
