Fractional Sizes Grade 2 Hex Head Cap Screw
Fractional Size Grade 2 Hex Head Cap Screws for Everyday Fastening
Fractional Size Grade 2 Hex Head Cap Screws are a trusted fastening solution for light- to medium-duty applications where reliability, ease of installation, and cost efficiency matter most. Featuring a classic six-sided hex head, these fasteners allow for smooth wrench engagement and controlled torque, making them ideal for general-purpose use across a wide range of industries.
General-Purpose Strength and Versatility
Manufactured from low- or medium-carbon steel, Grade 2 hex head cap screws are the most commonly specified fasteners for non-critical bolting applications. They provide dependable holding power without the added cost of higher-strength grades, making them a practical choice for machinery assembly, woodworking, agricultural equipment, light fabrication, and routine maintenance tasks. Their balanced strength profile ensures durability while remaining easy to install and remove.
Fractional Sizing and Industry Standards
These hex head cap screws are produced in standard fractional (inch) sizes, making them fully compatible with U.S.-standard hardware systems. They conform to ASME B18.2.1 dimensional requirements and meet SAE J429 mechanical property specifications for Grade 2 fasteners. With a minimum tensile strength of approximately 60,000 psi—up to 74,000 psi when heat treated—these screws deliver consistent performance in everyday fastening applications.
Finish Options and Compatibility
Fractional Size Grade 2 hex head cap screws are commonly available in plain steel or zinc-plated finishes. Zinc plating enhances corrosion resistance for mild outdoor or humid environments, while plain finishes offer a cost-effective option for indoor or dry conditions. These fasteners pair easily with standard hex nuts and flat or lock washers to create secure, vibration-resistant assemblies.
