- Superior corrosion resistance from the zinc plating extends service life and maintains integrity in harsh industrial environments.
- High hardness rating (Rockwell C25) provides excellent wear resistance and durability for repeated use.
- Coarse UNC threads offer faster installation and better performance in materials prone to stripping or cross-threading.
- Full threading along the entire 3" length allows for maximum grip and adjustability in various material thicknesses.
- External hex drive design enables high torque application with standard tools, ensuring secure and efficient fastening.
- Class 2A thread fit guarantees proper engagement and consistent performance while maintaining easy assembly.
Professional Applications & Engineering Value
Engineered for heavy-duty industrial applications, these Grade 5 hex head screws provide critical solutions where vibration resistance and structural integrity are paramount. The zinc plated steel construction combats corrosion in manufacturing plants, construction sites, and machinery assembly, while the coarse UNC thread design prevents loosening under dynamic loads. With full threading along the 3" length, these fasteners offer versatile clamping force distribution across thick materials and structural components. The external hex drive accommodates high-torque applications, making them ideal for equipment maintenance, structural steel connections, and industrial machinery where reliable fastening solutions are essential for operational safety and longevity.
Specification Summary & Compliance
This 3/4"-10 hex head screw features Class 2A thread fit per ASME standards, ensuring precise dimensional accuracy and proper thread engagement. Manufactured to meet ASME B18.2.1 and SAE J429 specifications for Grade 5 fasteners, with full compliance to RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations. The inch system measurements maintain consistency with North American industrial standards for seamless integration into existing designs and applications.
