- Precise and secure fastening thanks to the Class 3A thread fit and UNC coarse threading, ensuring consistent engagement and vibration resistance.
- Easy installation and removal with a hex socket drive and knurled head, offering superior grip and torque application.
- Accurate alignment and spacing provided by the precision-machined shoulder, maintaining component positioning.
- Compliance with industry standards including ASME B18.3, RoHS 3, and REACH, ensuring safety and regulatory adherence.
Professional Applications & Engineering Value
This 316 stainless steel shoulder screw is engineered to address critical challenges in industrial settings, such as misalignment, corrosion, and mechanical stress. The black oxide finish not only enhances corrosion resistance but also reduces galling, making it suitable for high-motion assemblies in machinery, automotive, and aerospace sectors. Its UNC coarse thread and Class 3A fit provide reliable fastening in vibrating environments, while the precise shoulder diameter and length ensure accurate component spacing and rotational stability. Ideal for pivots, bearings, and linkages, this screw delivers long-term reliability and reduces maintenance needs, supporting efficient B2B procurement for heavy-duty industrial applications.
Specification Summary & Compliance
This shoulder screw features a 10-24 UNC thread with Class 3A fit for high precision, alongside a shoulder diameter of 1/4" and length of 7/16" with tight tolerances. It meets ASME B18.3 specifications for dimensional accuracy and is compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and material integrity.
