Value Collection MP39107 Hex Head Cap Screw 1/2-13 Grade 8

Product Description

The VALUE COLLECTION MP39107 is a fully threaded hex head cap screw designed for high-strength fastening applications in industrial, mechanical, and structural assemblies. Manufactured from Grade 8 steel with a zinc yellow dichromate finish, this fastener delivers superior tensile strength and corrosion resistance compared to lower-grade alternatives. The 1/2-13 UNC thread size and 1-3/4 inch length under head make it a common choice for heavy-duty bolted connections. Sold in a package quantity of 25, it suits both shop stock and field service needs. Licensed trades and maintenance professionals working in fabrication, equipment repair, and structural work will find this screw meets standard load-bearing requirements.

This fastener is suited for use in industrial machinery, structural steel connections, automotive, and heavy equipment applications where a high-strength, inch-series hex cap screw is specified. The fully threaded configuration provides thread engagement along the full length under the head, which is preferred in applications requiring maximum grip or where thinner material stacks are fastened. The zinc yellow dichromate coating provides a baseline level of corrosion protection in moderate environments.

Key Features

• Grade 8 steel construction for high tensile and proof load strength
• Zinc yellow dichromate finish for corrosion resistance and identification
• Fully threaded along entire length under head for maximum thread engagement
• 1/2-13 UNC thread form per ASME B18.2.1 and SAE J429 standards
• Inch measurement system; length measured under head
• Sold in a 25-piece package to support stock replenishment and batch jobs

Compatibility

Designed as a standard inch-series hex head cap screw compatible with any application specifying a 1/2-13 UNC, Grade 8 fully threaded fastener per ASME B18.2.1 or SAE J429.

Installation Notes

Installation should be performed by qualified mechanical, structural, or maintenance trades familiar with torque specifications appropriate to Grade 8 fasteners and the joint material being assembled. Always verify the mating thread is clean and undamaged before installation. Use calibrated torque tools and follow applicable engineering or equipment manufacturer specifications for the application. Do not mix Grade 8 fasteners with lower-grade nuts or threaded inserts not rated for the corresponding load.
