Value Collection D39185 Hex Head Cap Screw 3/4-10 X 6-1/2 in

Product Description

The VALUE COLLECTION D39185 is a partially threaded hex head cap screw designed for heavy-duty fastening applications. It features a 3/4-10 UNC thread size and measures 6-1/2 inches under the head, making it suited for thick-material clamping and structural assembly work. Manufactured from Grade 8 steel with a zinc yellow dichromate finish, it offers high tensile strength and corrosion resistance. This fastener meets ASME B18.2.1 and SAE J429 standards, confirming dimensional accuracy and mechanical performance. It is a reliable choice for demanding industrial, mechanical, and trade installations where high-strength hardware is required.

This cap screw is commonly used in structural steel connections, heavy equipment assembly, HVAC mounting frames, electrical enclosure brackets, and general mechanical applications requiring a high-strength UNC fastener. Its partial threading allows for greater grip in thick material stackups where a fully threaded fastener would not seat correctly. It is a standard choice for maintenance technicians, millwrights, and trade professionals working with inch-measurement hardware in demanding environments.

Key Features

• Grade 8 steel construction provides high tensile and proof load strength for demanding applications
• Zinc yellow dichromate finish offers corrosion resistance and identification as a high-strength fastener
• Partially threaded shank allows proper clamping in thick material assemblies
• 3/4-10 UNC thread standard ensures broad compatibility with inch-measurement hardware
• Meets ASME B18.2.1 and SAE J429 standards for dimensional and mechanical compliance

Compatibility

Designed for use in standard 3/4-10 UNC tapped holes and nuts in structural, mechanical, and general industrial assemblies requiring Grade 8 high-strength fasteners in the inch measurement system.

Installation Notes

Installation should be performed by a qualified technician or trades professional using the appropriate hex socket or open-end wrench sized for a 3/4-inch hex head. Always ensure the mating nut or tapped hole is clean and free of debris before assembly. Grade 8 fasteners require proper torque application per the relevant engineering specification or applicable code for the assembly. Do not substitute Grade 8 hardware with lower-grade fasteners in safety-critical connections.
