Value Collection C703302 Hex Head Cap Screw 9/16-12 Grade 8

Product Description

The VALUE COLLECTION C703302 is a fully threaded hex head cap screw manufactured from Grade 8 steel in an uncoated finish. It features a 9/16-12 UNC thread size with a 1.25-inch length under the head. Grade 8 steel delivers high tensile strength suitable for heavy-duty fastening applications. The fully threaded shank allows maximum clamping engagement across the entire grip length. This fastener conforms to ASME B18.2.1 dimensional standards, ensuring consistent fit across standard hex tooling and torque specifications. These screws are commonly installed by maintenance technicians, millwrights, and mechanical contractors working on structural, equipment, and machinery assemblies.

This hex head cap screw is appropriate for industrial, commercial, and mechanical assembly applications requiring a high-strength fastener. The 9/16-12 UNC thread and Grade 8 material rating make it well suited for bolted joints subject to significant load, vibration, or shear stress. Sold in a package quantity of 50, this fastener is a practical choice for service shops, maintenance facilities, and contractors who need a reliable supply of high-strength inch-series fasteners on hand for recurring jobs.

Key Features

• Grade 8 steel construction for high tensile and proof load strength
• Fully threaded shank for maximum thread engagement across full grip length
• 9/16-12 UNC thread standard ensures compatibility with standard inch-series nuts and tapped holes
• Uncoated finish suitable for applications where coating thickness tolerance is critical or secondary finishing is planned
• Conforms to ASME B18.2.1 dimensional standards for consistent hex geometry and length tolerances
• Packaged in quantities of 50 for shop stock and field service use

Compatibility

Designed for use with standard 9/16-12 UNC inch-series nuts, washers, and tapped holes conforming to ASME and ANSI inch fastener standards.

Installation Notes

Installation should be performed by a qualified technician using a calibrated torque wrench and the appropriate hex socket or open-end wrench for 9/16-12 fasteners. Follow the joint design specification for proper torque values, as Grade 8 fasteners require higher torque than lower-grade equivalents. Inspect threads for damage before installation and ensure the mating nut or tapped hole is free of debris. Do not reuse fasteners that have been subjected to yield-level or impact loading.
