Key Features & Benefits at a Glance
- Exceptional corrosion resistance with 18-8 Stainless Steel construction, ideal for harsh environments and extended service life.
- Superior load-bearing capability thanks to a high 70,000 psi tensile strength and Rockwell B70 hardness for reliable performance under stress.
- Precise and secure fastening ensured by the Class 3A thread fit, minimizing the risk of loosening in critical assemblies.
- Optimized for high-torque applications with a standard 1/2" hex drive and socket head, providing a secure grip and reducing tool slippage.
- Versatile full-threaded design allows for consistent engagement along the entire 1-1/4" length, accommodating various material thicknesses.
- Enhanced vibration resistance from the fine (UNF) thread spacing, maintaining joint integrity in dynamic operating conditions.
- Guaranteed quality and safety compliance by meeting ASME B18.3 specifications and being RoHS 3 & REACH compliant.
Professional Applications & Engineering Value
This Socket Head Cap Screw is engineered to address common industrial challenges such as joint failure under high vibration and corrosion in demanding environments. Manufactured from 18-8 Stainless Steel, it provides excellent resistance to rust and chemical exposure, making it a reliable choice for machinery, automotive, and marine applications. The Class 3A thread fit and fine UNF threading ensure a tight, precise fit that reduces the need for frequent retightening, enhancing assembly efficiency and safety. Its high tensile strength and standard hex drive allow for easy installation in confined spaces, supporting robust performance in high-stress engineering projects where durability and precision are non-negotiable.
Specification Summary & Compliance
This screw features a 5/8"-18 UNF thread with a Class 3A fit for high precision, a 1-1/4" length, and a 1/2" hex drive. It is manufactured in accordance with ASME B18.3 standards and complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and material quality for industrial use.
