Key Features & Benefits at a Glance
- Exceptional strength for demanding applications with Grade 8 classification, ensuring reliable performance under high stress and vibration.
- Superior corrosion resistance provided by the zinc yellow-chromate plating, extending service life in harsh industrial environments.
- Optimized for easy installation and high clamp load thanks to the coarse UNC thread and external hex drive design.
- Consistent and precise fit with Class 2A thread tolerance, reducing the risk of cross-threading and assembly errors.
- Maximum grip and holding power from being fully threaded along the entire 1-inch length.
- High durability and wear resistance due to the Rockwell C33 hardness, maintaining integrity under repeated use.
- Guaranteed material and manufacturing quality with compliance to ASME B18.2.1 and SAE J429 standards.
Professional Applications & Engineering Value
This Grade 8 hex head screw is engineered to address critical challenges in heavy machinery, construction, and automotive assemblies where failure is not an option. The steel material combined with a zinc yellow-chromate finish provides a robust barrier against oxidation and chemical exposure, significantly reducing maintenance costs and downtime. The 7/16"-14 UNC coarse thread ensures quick assembly and superior resistance to loosening under dynamic loads, while the external hex drive allows for high torque application with standard tools. Ideal for structural connections, equipment frames, and high-vibration environments, this fastener delivers reliable performance, ensuring long-term operational safety and efficiency in demanding industrial applications.
Specification Summary & Compliance
This product adheres to precise dimensional standards, including Class 2A thread fit for consistent engagement and UNC coarse threading with a 7/16"-14 size. It meets ASME B18.2.1 and SAE J429 specifications for material and mechanical properties. Additionally, it is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and regulatory acceptance in global markets.
