Value Collection 97027 5/16-18 X 3/4 in Grade 5 Hex Cap Screw 100pk

Product Description

The VALUE COLLECTION 97027 is a fully threaded hex head cap screw in a 5/16-18 UNC thread size with a 3/4 inch length under the head. Made from Grade 5 steel with a bright, uncoated finish, this fastener meets ASME B18.2.1 dimensional standards for inch-series hex cap screws. It is a general-purpose structural fastener suited for mechanical assemblies, equipment fabrication, and maintenance applications across HVAC, plumbing, and electrical trades. The package contains 100 pieces, making it practical for technicians who routinely stock fasteners for service and installation work.

This screw is used in a wide range of light-to-medium duty fastening applications where a standard UNC thread pattern and hex drive are required. Common installation scenarios include panel mounting, bracket fastening, equipment enclosures, and field repairs on residential and commercial mechanical systems. The fully threaded shank provides consistent clamping through thinner material sections where a partially threaded grip would not engage properly.

Compatibility

Designed as a standard inch-series hex cap screw compatible with any UNC 5/16-18 tapped hole or nut per ASME B18.2.1 specifications.

Installation Notes

Install with a standard hex wrench, socket, or adjustable wrench sized for a 5/16 inch cap screw head. Ensure mating threads are clean and free of debris before fastening. Follow applicable torque guidelines for Grade 5 steel fasteners as specified by the equipment manufacturer or relevant industry standards. Do not use impact tools at full torque on fine or lightly tapped blind holes, as thread stripping can occur.
