Technical Specifications

Technical Features

• Hexagonal head design: Engineered to be driven by a standard wrench, allowing high torque application without slippage during installation.
• 5/16-18 coarse thread: The 18 threads-per-inch coarse pitch allows faster engagement and is less susceptible to cross-threading compared to fine-thread variants, improving installation speed in field conditions.
• Grade 5 rating: Meets the medium-strength classification standard, making these screws suitable for demanding general-purpose structural and mechanical fastening applications.
• 3/4 in. length: A compact shank length suited for fastening applications where material stack depth is limited.
• Box of 100: Bulk packaging reduces per-unit cost and ensures an adequate supply for repeat or large-volume fastening tasks on the job site.

Applications

• General-purpose structural assembly in construction and manufacturing environments
• Mechanical component fastening where medium-strength hardware is specified
• Equipment assembly and maintenance requiring wrench-driven hex fasteners
• Any application calling for a 5/16-18 coarse thread hex cap screw at 3/4 in. length
