Value Collection 99027 5/16-18 X 3/4 in Grade 8 Cap Screw 100pk

Product Description

The VALUE COLLECTION 99027 is a fully threaded hex head cap screw designed for high-strength fastening applications in industrial, mechanical, and trade environments. Manufactured from Grade 8 steel with no additional finish coating, this fastener measures 5/16-18 thread size with a 3/4-inch length under head. The UNC thread form and ASME B18.2.1 compliance make it a dependable choice for structural connections requiring a recognized dimensional standard. Sold in a package of 100, the 99027 is appropriate for contractors, maintenance technicians, and field service professionals who need reliable quantity stock of a common fastener size.

This cap screw is used across a wide range of applications including HVAC equipment mounting, electrical enclosure assembly, plumbing bracket installation, and general mechanical assembly where a Grade 8 tensile rating is specified. The fully threaded configuration allows engagement along the full length of the shank, making it well suited for thin-stock applications and through-bolt installations where maximum thread engagement is required.

Key Features

• Grade 8 steel construction provides high tensile and proof load ratings for demanding mechanical connections
• Fully threaded shank allows complete thread engagement through the full 3/4-inch length under head
• UNC 5/16-18 thread form is a widely used standard size compatible with common nuts and tapped holes
• Uncoated finish — suitable for use with added corrosion protection where required by the application
• Conforms to ASME B18.2.1 dimensional standard for consistent, interchangeable fit
• Package of 100 units supports bulk stocking and job-site replenishment needs

Compatibility

Designed as a standard-dimension replacement or stocking fastener for any application calling for a 5/16-18 UNC fully threaded hex head cap screw meeting ASME B18.2.1 specifications.

Installation Notes

Installation should be performed by qualified trade professionals using the appropriate hex wrench or socket. Always verify that mating nuts or tapped holes are the correct 5/16-18 UNC thread class before installation. Grade 8 fasteners require proper torque to achieve rated clamp load — refer to the applicable torque specification table for the fastener grade and diameter. Inspect threads for damage before use and do not reuse fasteners that show signs of galling, stretching, or corrosion.
