Key Features & Benefits at a Glance
- Exceptional tensile strength of 120,000 psi ensures reliable performance in demanding applications, reducing the risk of fastener failure.
- Superior corrosion resistance from zinc plating extends service life and maintains integrity in harsh environments.
- High hardness rating (Rockwell C25) provides excellent wear resistance, minimizing deformation under heavy loads.
- Coarse UNC threading offers faster installation and better performance in materials where fine threads might strip.
- Full threading along the 9" length allows for maximum adjustability and secure fastening across the entire shank.
- Class 2A thread fit ensures consistent, reliable engagement with standard nuts and tapped holes, speeding up assembly.
- External hex drive design enables high torque application with common tools, facilitating quick and secure tightening.
Professional Applications & Engineering Value
This Grade 5 steel hex head screw is engineered to address critical challenges in heavy-duty industrial applications, such as construction, machinery assembly, and structural frameworks. The 3/8"-16 UNC coarse thread provides superior grip in softer materials or where vibration resistance is paramount, while the zinc plating significantly enhances durability against corrosion, reducing maintenance needs. With a fully threaded 9" length, it ensures uniform load distribution and versatile positioning, making it ideal for projects requiring long, robust fasteners that meet stringent ASME B18.2.1 and SAE J429 standards. Its 120,000 psi tensile strength and Rockwell C25 hardness deliver reliable performance under stress, minimizing downtime and enhancing safety in demanding environments.
Specification Summary & Compliance
This fastener adheres to precise Class 2A thread fit tolerances and UNC coarse thread standards, ensuring compatibility and ease of use. It meets ASME B18.2.1 and SAE J429 specifications for dimensional accuracy and performance, and is RoHS 3 (2015/863/EU) compliant, supporting environmental and safety regulations in industrial settings.
