Professional Applications & Engineering Value
This 5/16"-24 UNF shoulder screw is engineered to address critical alignment and durability challenges in industrial machinery. The alloy steel material, combined with Rockwell C32 hardness, withstands repetitive loads and harsh operating conditions, reducing maintenance frequency. The black oxide finish enhances corrosion resistance, making it ideal for automotive, aerospace, and manufacturing equipment where exposure to oils and moisture is common. The Class 3A thread fit and fine thread spacing provide vibration-resistant fastening, while the standard shoulder ensures precise component positioning in rotating assemblies and linkages, minimizing wear and improving operational accuracy.
Specification Summary & Compliance
This shoulder screw features a Class 3A thread fit with UNF fine thread standards, ensuring high precision in demanding applications. Key dimensional tolerances include a shoulder diameter of 3/8" (-0.004" to -0.002") and shoulder length of 5/8" (-0.005" to 0.005") for consistent performance. It complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming its adherence to environmental and safety standards for industrial use.
