Key Features & Benefits at a Glance
- Superior corrosion resistance with 316 stainless steel construction, ideal for harsh industrial environments and extended service life.
- Enhanced durability and wear resistance from the black oxide finish, which also provides a sleek, non-reflective surface.
- Precise and secure fastening ensured by the Class 3A thread fit, minimizing the risk of loosening under vibration.
- High mechanical strength with 70,000 psi tensile and 35,000 psi shear strength, reliably supporting heavy loads in demanding applications.
- Easy installation and removal using a standard hex drive (1/8"), combined with a knurled head for improved grip and handling.
- Accurate alignment and spacing provided by the precision shoulder diameter and length, critical for machinery and assembly operations.
- Compliance with major 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 common industrial challenges 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. With a Class 3A thread fit and UNC coarse thread, it offers reliable engagement in materials prone to stripping, while the precision shoulder ensures consistent part spacing in machinery, pivots, and rotating components. Ideal for industrial applications like automotive, aerospace, and manufacturing equipment, this screw provides long-term performance by resisting chemical exposure and maintaining high tensile and shear strength under dynamic loads.
Specification Summary & Compliance
The screw features a 10-24 UNC thread with Class 3A fit for tight tolerances, and a shoulder diameter of 1/4" with precise length control. It conforms to ASME B18.3 manufacturing standards and is compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it is free of hazardous substances for safe use in various industries.
