Key Features & Benefits at a Glance
- Superior corrosion resistance with 18-8 stainless steel construction, ideal for harsh industrial environments.
- Exceptional mechanical strength with 70,000 psi tensile strength and Rockwell B70 hardness for reliable, long-term performance.
- Precise Class 3A thread fit ensures tight, secure fastening with minimal backlash in critical assemblies.
- Fully threaded design provides consistent clamping force along the entire 11/16" length for uniform load distribution.
- Hex socket drive (3/32") allows high-torque installation with standard tools, reducing slippage and head stripping.
- Coarse UNC threads enable quick assembly and disassembly, even in applications with debris or vibration.
- Compliance with ASME and ASTM standards guarantees consistent quality and interchangeability for engineering projects.
Professional Applications & Engineering Value
This socket head cap screw is engineered to address common industrial challenges, such as vibration loosening and corrosion-induced failure. The 18-8 stainless steel material offers excellent resistance to oxidation and chemical exposure, making it suitable for machinery, automotive, and outdoor equipment. The 4-40 UNC coarse thread and Class 3A fit provide superior engagement in tapped holes, reducing the risk of cross-threading and ensuring reliable performance under dynamic loads. Its fully threaded design and hex drive facilitate efficient installation in confined spaces, while the high tensile strength supports heavy-duty applications without compromising integrity.
Specification Summary & Compliance
This screw features a 4-40 UNC coarse thread with Class 3A fit for precise dimensional accuracy. It complies with ASME B1.1, ASME B18.3, and ASTM F837 manufacturing standards, ensuring consistent quality and performance. The product is RoHS 3 (2015/863/EU) Compliant, meeting environmental regulations for hazardous substance restrictions.
