Key Features & Benefits at a Glance
- Exceptional tensile strength with 120,000 psi rating ensures reliable performance in high-stress applications, reducing the risk of fastener failure.
- Superior corrosion resistance from zinc plating extends service life in harsh environments, minimizing maintenance and replacement costs.
- High hardness (Rockwell C25) provides excellent wear resistance, maintaining thread integrity through repeated use and tightening.
- Coarse UNC thread design offers faster installation and superior holding power in softer materials or where vibration resistance is critical.
- Precision Class 2A thread fit ensures smooth assembly and consistent clamping force, reducing installation time and improving joint reliability.
- Full threading along the 3½" length allows for maximum adjustability and secure fastening across varying material thicknesses.
- External hex drive design enables high-torque application with standard tools, facilitating quick and secure installations in industrial settings.
Professional Applications & Engineering Value
This Grade 5 hex head screw delivers critical engineering solutions for heavy-duty applications where structural integrity and long-term reliability are paramount. The zinc plated steel construction combats corrosion in industrial environments, from machinery assembly to structural frameworks, while the 7/16"-14 UNC coarse thread provides excellent resistance to loosening under vibration. With 120,000 psi tensile strength and Rockwell C25 hardness, this fully threaded fastener maintains clamp load in demanding applications, preventing joint failure in construction equipment, automotive components, and heavy machinery where high-strength fasteners are essential for operational safety and durability.
