Professional Applications & Engineering Value
This alloy steel shoulder screw is engineered to address critical challenges in industrial applications where precision and reliability are paramount. The 10-24 UNC coarse thread and 3" shoulder length with tight tolerances provide exact positioning and rotational support in machinery, automotive assemblies, and precision equipment. The black oxide finish enhances corrosion resistance, reducing maintenance in humid or corrosive settings. With a socket head and hex drive, it allows for efficient installation in confined spaces, while the knurled head improves handling. Ideal for heavy-duty fastening, it ensures long-term performance by resisting wear and deformation under high loads.
Specification Summary & Compliance
This shoulder screw features precise dimensions, including a 3/8" thread length and 3" shoulder length with tolerances of -0.005" to 0.005" for shoulder length and -0.004" to -0.002" for shoulder diameter. It adheres to Class 3A thread fit and UNC thread standards, manufactured under ASME B18.3 specifications. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006), it meets environmental and safety regulations for global use.
