Fractional Size Grade 5 Hex Head Cap Screws with Plain Finish
Fractional Size Grade 5 Hex Head Cap Screws with a plain finish are engineered for dependable strength and consistent performance in medium-duty fastening applications. Commonly used across industrial manufacturing, automotive repair, equipment assembly, and maintenance operations, these fasteners provide the ideal balance between high strength and practical versatility.
Heat-Treated Strength for Demanding Applications
Manufactured from heat-treated medium carbon steel, Grade 5 hex head cap screws are designed to outperform lower-grade fasteners in applications exposed to stress, vibration, and repeated loading. With a minimum tensile strength of 120,000 psi and a yield strength of 92,000 psi, these fasteners deliver reliable clamping force and resistance to shear in critical assemblies. This makes them a preferred choice for machinery components, automotive systems, agricultural equipment, and structural connections where durability is essential.
Plain Finish for Controlled Environments
The plain, uncoated finish offers a clean and economical solution for indoor or dry environments where corrosion protection is not a primary requirement. This finish preserves the fastener’s original mechanical properties and provides excellent surface friction for applications requiring paint, powder coating, or other secondary finishes. Plain finish Grade 5 fasteners are often specified in OEM manufacturing and controlled assembly settings.
Precision Design and Fractional Sizing
Each Grade 5 hex head cap screw features a six-sided head that allows for easy wrenching and precise torque application without rounding. Available in standard fractional (inch) sizes, these fasteners are fully compatible with U.S. hardware systems. They conform to ASME B18.2.1 dimensional standards and meet SAE J429 mechanical property requirements, ensuring consistent fit, reliable threading, and repeatable performance.
