Fractional Size Grade 5 Hex Head Cap Screw
Fractional Size Grade 5 Hex Head Cap Screws: High-Strength Performance for Demanding Industrial Applications
The Fractional Size Grade 5 Hex Head Cap Screw is engineered for strength, durability, and reliability in medium- to heavy-duty fastening applications. Recognized for its six-sided hexagonal head, this fastener allows for easy wrenching, precise torque application, and a secure fit—making it one of the most widely used bolts in industrial, automotive, and machinery assembly.
Manufactured from medium carbon steel and heat-treated for enhanced strength, Grade 5 hex head cap screws deliver a minimum tensile strength of 120,000 psi and a yield strength of 92,000 psi. This superior performance makes them ideal for use in automotive components, farm equipment, machinery, and construction where resistance to stress and vibration is critical.
These screws are produced in fractional (Fractional) sizes, conforming to ASME B18.2.1 dimensional standards and SAE J429 mechanical property requirements. The precise threading ensures consistent load distribution and reliable tightening under repeated use.
Available in multiple finishes, including zinc-plated for corrosion resistance and plain steel for cost-effective applications, Grade 5 fasteners provide long-lasting performance across diverse environments. The hex head design ensures superior grip, allowing for higher torque without stripping or rounding.
