Value Collection D39474 Hex Head Cap Screw 3/4-16 X 2-1/2 in

Product Description

The VALUE COLLECTION D39474 is a fully threaded hex head cap screw designed for high-strength fastening applications in mechanical, industrial, 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 3/4-16 UNF thread form provides fine-pitch engagement for applications requiring precise torque control and vibration resistance. At 2.5 inches in length under head, it suits a wide range of medium-depth through-bolt and tapped-hole installations. Conforms to ASME B18.2.1 standards, making it suitable for use in environments with strict fastener specification requirements.

This cap screw is used across industrial maintenance, heavy equipment repair, agricultural machinery, and fabrication work where high-load fastening is required. The fully threaded shank maximizes thread engagement in tapped holes and is well suited for shorter grip-length applications. Machinists, millwrights, maintenance technicians, and field service mechanics commonly use Grade 8 fasteners of this type when working with steel structures and equipment subject to dynamic or shock loading.

Key Features

• Grade 8 steel construction provides high tensile and proof load strength for demanding fastening applications
• Zinc yellow dichromate finish offers corrosion resistance and a distinctive identification coating standard for Grade 8 hardware
• Fully threaded shank for maximum thread engagement in tapped holes
• 3/4-16 UNF fine-pitch thread for precise torque control and vibration resistance
• Conforms to ASME B18.2.1 dimensional standards for consistent fitment and interchangeability

Compatibility

Designed as a standard inch-series hex head cap screw for use in any application requiring a 3/4-16 UNF fully threaded fastener conforming to ASME B18.2.1 specifications.

Installation Notes

Installation is performed by qualified mechanics or maintenance technicians using standard hex or socket wrenches sized for a 3/4-inch hex head cap screw. Always ensure mating threads are clean and free of debris before installation. Do not mix Grade 8 fasteners with lower-grade nuts or threaded components that cannot sustain equivalent load ratings. Follow applicable industry or equipment manufacturer torque specifications for the specific joint and material.
