- High-strength performance with 70,000 psi tensile strength and 35,000 psi shear strength for reliable use in demanding applications.
- Precise alignment and smooth rotation ensured by the 5 1/2" shoulder with standard fit and tight diameter tolerance.
- Secure, non-slip installation facilitated by the knurled socket head and 1/8" hex drive, allowing for high torque application.
- Consistent, reliable threading with Class 3A fit and 10-24 UNC coarse threads for easy assembly and strong holding power.
- 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 failure. The black oxide finish enhances surface hardness and reduces friction, making it suitable for high-motion assemblies in machinery, automotive, and aerospace sectors. The 10-24 UNC coarse thread and Class 3A thread fit provide excellent engagement and vibration resistance, while the precise shoulder diameter and length ensure accurate component positioning. Ideal for use in pivots, guides, and spacers, this screw offers long-term reliability and reduces maintenance needs in industrial applications.
Specification Summary & Compliance
This shoulder screw features a 10-24 UNC thread with Class 3A fit for precise threading. The shoulder diameter is 1/4" with a tolerance of -0.004" to -0.002", and the shoulder length is 5 1/2" with a tolerance of -0.005" to 0.005". Manufactured to ASME B18.3 specifications, it also complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and material quality.
