Professional Applications & Engineering Value
This alloy steel shoulder screw is engineered to address critical challenges in precision assemblies, such as misalignment and component wear. The 3/8"-24 UNF fine thread with Class 3A fit provides excellent clamping force and vibration resistance, ideal for machinery, automotive, and aerospace applications where high tensile strength (140,000 psi) is essential. The black oxide finish enhances corrosion resistance, while the precisely machined shoulder (1/2" diameter with tight tolerances) ensures accurate alignment of parts like bearings and pulleys, reducing maintenance downtime. Its knurled head and 1/4" hex drive facilitate quick installation in confined spaces, making it a reliable choice for demanding industrial environments.
Specification Summary & Compliance
This shoulder screw adheres to inch system dimensions with a Class 3A thread fit for superior precision. Key specifications include a shoulder diameter of 1/2" (tolerance: -0.004" to -0.002") and shoulder length of 1 1/8" (tolerance: -0.005" to 0.005"). It complies with RoHS 3 (2015/863/EU) under exemption 6(a) and REACH (EC 1907/2006), ensuring environmental and safety standards are met for industrial use.
