• Superior corrosion resistance from zinc yellow-chromate plating extends service life in harsh industrial environments
• Built-in tension indicating feature provides visual confirmation of proper 10,000 lbs preload, preventing under or over-tightening
• High-temperature capability (0° to 165°F) maintains structural integrity in varied operating conditions
• Grade 8 strength classification with Rockwell C33 hardness delivers maximum durability for heavy machinery and construction
• Precision Class 2A thread fit ensures smooth installation and secure fastening in coarse-threaded applications
• Partially threaded design provides optimal grip and clamping force where full threading isn't required

Professional Applications & Engineering Value

This Grade 8 hex head screw with 1/2"-13 UNC coarse threading addresses critical engineering challenges in heavy industrial applications. The zinc yellow-chromate plated steel construction provides superior corrosion protection while maintaining the 150,000 PSI tensile strength required for structural connections. The tension indicating feature solves the common problem of improper bolt preload in machinery assembly, construction projects, and equipment manufacturing. With Rockwell C33 hardness and temperature resistance from 0° to 165°F, this partially threaded fastener delivers reliable performance in demanding environments where vibration resistance and long-term durability are essential. The external hex drive design allows for high-torque installation using standard tools.

Specification Summary & Compliance

This heavy-duty hex head screw features precision Class 2A thread fit with 1/2"-13 UNC coarse thread spacing and right-hand thread direction. Manufacturing complies with REACH (EC 1907/2006) regulations, ensuring environmental compliance for industrial use. The fastener meets Grade 8 strength classification standards with dimensions including 2" length, 3/4" head width, and minimum 1-1/4" thread length. Partially threaded design and external hex drive provide optimal performance for industrial and construction applications requiring high-strength fastening solutions.
