Value Collection MPKP44080 Hex Cap Screw 1/2-13 X 2 in Grade 8

Product Description

The VALUE COLLECTION MPKP44080 is a partially threaded hex head cap screw designed for high-strength bolted connections in structural, mechanical, and industrial assemblies. Manufactured from Grade 8 steel and finished with a zinc plating for corrosion resistance, this fastener meets ASTM A354 BD standards. The 1/2-13 UNC thread size and 2-inch length under head make it a standard choice for heavy-duty fastening applications where tensile strength and dimensional consistency are critical. Sold in packages of 10, it suits both job-site use and shop inventory restocking.

This hex head cap screw is suited for structural steel connections, machinery frames, equipment mounting, and general industrial fabrication. The partial threading allows for a smooth shank bearing surface in clearance holes, which is preferred in applications requiring shear load transfer or precise clamp-force control. Licensed tradespeople, maintenance mechanics, and fabricators working in commercial and industrial settings will find this fastener meets the dimensional and mechanical requirements of most Grade 8 fastening specifications.

Key Features

• Grade 8 steel construction meets ASTM A354 BD for high-strength fastening
• 1/2-13 UNC thread — standard inch-series coarse thread for broad tool compatibility
• Partially threaded shank provides a smooth bearing surface for shear-loaded joints
• Zinc-plated finish offers basic corrosion protection in dry and mildly humid environments
• 2-inch length under head suits medium-depth through-bolt and flange applications
• Packaged in quantities of 10 for convenient job-lot use

Compatibility

Designed as a standard 1/2-13 UNC Grade 8 hex head cap screw compatible with any application calling for ASTM A354 BD partially threaded fasteners in that thread size and length.

Installation Notes

Installation should follow applicable torque specifications for Grade 8 fasteners as defined by the governing standard or engineer of record — consult the relevant specification for the required clamp load. Use a calibrated torque wrench and the correct 3/4-inch hex socket or wrench. Ensure mating threads and bearing surfaces are clean and free of debris before assembly. Do not substitute a lower-grade fastener in any application specifying Grade 8.
