Professional Applications & Engineering Value
This alloy steel shoulder screw is engineered to address common challenges in machinery and automation, such as misalignment and component wear. The black oxide finish not only enhances corrosion resistance but also reduces friction in moving parts. With a Class 3A thread fit and UNC coarse thread spacing, it ensures quick assembly and high clamping force, reducing the risk of loosening under vibration. The knurled socket head provides a secure grip for hex drivers, speeding up maintenance in tight spaces. Ideal for use in precision industrial applications like pivots, gears, and linkages, this shoulder screw delivers consistent performance and long-term reliability, minimizing downtime and replacement costs.
Specification Summary & Compliance
This shoulder screw adheres to Class 3A thread fit and UNC thread standards for precise dimensional accuracy, with shoulder diameter tolerance of -0.004" to -0.002" and shoulder length tolerance of -0.005" to 0.005". It meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, ensuring it is free from hazardous substances and suitable for various industrial and export markets.
