Value Collection D39027 Hex Cap Screw 5/16-18 X 3/4 in Grade 8

Product Description

The VALUE COLLECTION D39027 is a fully threaded hex head cap screw designed for high-strength fastening applications where torque resistance and corrosion protection are required. This fastener carries a Grade 8 steel rating, making it suitable for demanding structural and mechanical assemblies. The zinc yellow dichromate finish provides a baseline level of corrosion resistance while also serving as a visual indicator of the high-strength Grade 8 classification. Manufactured to ASME B18.2.1 standards, this screw meets established dimensional and performance specifications. It is sized at 5/16-18 UNC thread with a 3/4-inch length under head and weighs approximately 0.01 pounds per unit.

This cap screw is appropriate for use in general industrial, mechanical, and maintenance applications where Grade 8 strength is specified. Fully threaded construction makes it well-suited for through-bolt configurations or short-grip fastening scenarios. It is commonly installed by maintenance technicians, machinists, and millwrights working in manufacturing, equipment assembly, and structural repair environments. Minimum order quantity is 50 pieces per order.

Key Features

• Grade 8 steel construction for high tensile and proof-load strength
• Zinc yellow dichromate finish offers corrosion resistance and identifies Grade 8 classification
• Fully threaded along the entire shank length for maximum thread engagement
• 5/16-18 UNC thread form per standard inch thread specifications
• Manufactured to ASME B18.2.1 dimensional standards
• 3/4-inch length under head suits compact fastening configurations

Compatibility

Designed as a standard inch-series hex head cap screw for use with 5/16-18 UNC tapped holes or standard hex nuts and washers in Grade 8-compatible assemblies.

Installation Notes

Installation should be performed by qualified technicians familiar with fastener torque requirements for Grade 8 hardware. Use a properly sized hex wrench or socket to avoid rounding the head. Always verify that mating threads and hole specifications match the 5/16-18 UNC thread standard before installation. Do not exceed the rated torque capacity for the fastener grade or the joined material.
