Key Features & Benefits at a Glance
- Superior corrosion resistance with 18-8 stainless steel construction, ideal for harsh environments and long-term reliability.
- Enhanced load-bearing capacity from a 70,000 psi tensile strength and 35,000 psi minimum shear strength, ensuring secure, heavy-duty assemblies.
- Precise component alignment and reduced wear thanks to the 3/4" shoulder diameter with tight tolerance control.
- Quick and secure installation with a 3/8" hex socket drive and knurled head for improved grip and torque application.
- Reliable thread engagement and vibration resistance provided by the 5/8"-11 UNC coarse thread with Class 3A fit.
- Consistent performance backed by compliance with ASME B18.3 standards, ensuring dimensional accuracy and interchangeability.
- Environmentally responsible manufacturing with RoHS 3 and REACH compliance, meeting global regulatory requirements.
Professional Applications & Engineering Value
This shoulder screw is engineered to address critical alignment and rotational motion challenges in industrial machinery. The 18-8 stainless steel material provides excellent resistance to corrosion and oxidation, making it suitable for applications in food processing, marine, and chemical environments where moisture is a concern. The 3/4" shoulder diameter acts as a precise pivot or bearing surface, reducing friction and wear on moving parts, while the UNC coarse thread ensures rapid assembly and high resistance to loosening under vibration. With a hex socket drive and knurled head, it offers secure tool engagement and ease of handling in confined spaces. Ideal for use in jigs, fixtures, and conveyor systems, this fastener enhances equipment longevity and operational efficiency by maintaining precise tolerances and Class 3A thread fit.
Specification Summary & Compliance
This shoulder screw features a Class 3A thread fit for precise engagement and a shoulder diameter tolerance of -0.004" to -0.002" to ensure accurate alignment. It adheres to ASME B18.3 specifications for dimensional consistency and is compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming its safety and environmental standards.
