Key Features & Benefits at a Glance
- Superior corrosion resistance from 18-8 Stainless Steel construction, ideal for harsh environments and reducing replacement frequency
- Exceptional tensile strength of 70,000 psi ensures reliable performance under high-stress conditions and prevents fastener failure
- Precise Class 3A thread fit provides tighter tolerances for secure, vibration-resistant assemblies in demanding applications
- Partially threaded design allows for effective clamping while minimizing thread damage during installation
- High hardness (Rockwell B70) enhances wear resistance and extends service life in repetitive use scenarios
- 1/4" hex drive with standard socket head enables easy installation and removal with common tools, improving assembly efficiency
- Coarse 5/16"-18 UNC threads facilitate quicker installation and better performance in materials prone to stripping
Professional Applications & Engineering Value
This 18-8 Stainless Steel Socket Head Cap Screw is engineered to address critical industrial challenges, including corrosion in chemical processing, marine, and outdoor equipment. Its Class 3A thread fit and coarse UNC threading provide superior resistance to loosening under vibration, making it ideal for machinery, automotive assemblies, and structural frameworks. The partially threaded rod type ensures optimal grip without compromising thread integrity, while the high tensile strength supports heavy-load applications. With a standard socket head profile and 1/4" hex drive, it streamlines maintenance and reduces downtime in manufacturing and construction settings.
Specification Summary & Compliance
This screw adheres to ASME B18.3 specifications, ensuring dimensional accuracy and performance reliability. The Class 3A thread fit guarantees precise tolerances for secure fastening. It is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming its safety for use in regulated industries and environmental sustainability.
