Professional Applications & Engineering Value
This 3-48 UNC set screw is engineered to address common industrial challenges like component slippage and corrosion-induced failure. Crafted from black-oxide alloy steel, it resists rust and wear, making it suitable for machinery, automotive, and electronics where environmental exposure is a concern. The headless hex drive and cup tip design ensure a flush fit, minimizing protrusion and distributing clamping force evenly to prevent damage to secured parts. With a Class 3A thread fit and coarse threading, it offers quick assembly and high resistance to loosening under vibration, enhancing reliability in dynamic applications. Ideal for precision fastening in shafts, collars, and gears, this screw delivers consistent performance while adhering to strict industry standards.
Specification Summary & Compliance
This set screw features a 3-48 UNC coarse thread with Class 3A fit for precise dimensional accuracy, ensuring tight tolerances in assembly. It complies with ASME B18.3 specifications for consistent manufacturing quality, and meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming it is free from hazardous substances and safe for industrial use.
