Key Features & Benefits at a Glance
- Exceptional tensile strength of 150,000 PSI ensures reliable performance in high-stress industrial applications, reducing the risk of fastener failure.
- Superior corrosion resistance from zinc yellow-chromate plating extends service life in harsh environments, minimizing maintenance needs.
- High hardness rating (Rockwell C33) provides excellent wear resistance and durability under repeated loads.
- Coarse UNC threading allows for quicker installation and better grip in softer materials or where vibration is a concern.
- Full threading design offers consistent clamping force along the entire length, enhancing joint stability.
- External hex drive enables easy tightening with standard tools, improving assembly efficiency.
- Compliance with industry standards (ASME B18.2.1, SAE J429) guarantees dimensional accuracy and interoperability.
Professional Applications & Engineering Value
This Grade 8 hex head screw is engineered for demanding industrial settings where high tensile strength and corrosion resistance are critical. Made from robust steel and finished with zinc yellow-chromate plating, it effectively combats rust and degradation in environments exposed to moisture, chemicals, or outdoor elements. The 7/16"-14 UNC coarse thread ensures secure fastening in materials like cast iron or structural steel, reducing the likelihood of loosening under vibration. Ideal for heavy machinery, automotive assemblies, and construction projects, this fully threaded fastener delivers uniform stress distribution, preventing joint failure and extending equipment lifespan while meeting rigorous industrial standards.
Specification Summary & Compliance
This hex head screw features precise Class 2A thread fit and adheres to ASME B18.2.1 and SAE J429 specifications for dimensional consistency. It is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and material restrictions are met for global industrial use.
