Key Features & Benefits at a Glance
- Superior tensile strength of 160,000 PSI ensures reliable performance in high-stress applications, preventing fastener failure.
- Exceptional hardness (Rockwell C39) provides excellent wear resistance and durability, extending the screw's service life.
- Precision Class 3A thread fit guarantees secure, vibration-resistant assemblies with minimal risk of loosening.
- Corrosion-resistant cadmium plating on alloy steel offers enhanced protection in harsh industrial environments.
- Standard hex socket drive allows for high-torque installation and a clean, flush finish in confined spaces.
- Coarse UNRC thread design enables faster installation and better performance in materials like cast iron and softer alloys.
- Partially threaded shank provides an unthreaded bearing surface for improved clamping force and alignment.
Professional Applications & Engineering Value
Engineered for demanding industrial applications, this socket head cap screw is built from cadmium-plated alloy steel to combat corrosion and maintain integrity under extreme mechanical stress. The Class 3A thread fit and coarse UNRC threads ensure precise, reliable fastening in heavy machinery, automotive assemblies, and aerospace components, where vibration resistance is critical. Its high tensile strength and Rockwell C39 hardness make it ideal for high-load scenarios, preventing stripping and shearing. The hex socket drive facilitates secure tool engagement, allowing for efficient installation in tight spaces, reducing assembly time and improving overall structural reliability in industrial fastening systems.
Specification Summary & Compliance
This screw adheres to stringent dimensional and performance standards, including a Class 3A thread fit for precise tolerance and a coarse thread spacing per UNRC specifications. It is manufactured to meet MS16997-102 NAS1352-6-28P, ensuring compliance with industry-specific requirements for quality and reliability in aerospace and defense applications. The inch system measurements and material specifications confirm consistency with engineering designs, supporting traceability and performance validation in professional settings.
