Value Collection 99002 1/4-20 X 3/4 in Grade 8 Hex Cap Screw 100pk

Product Description

The VALUE COLLECTION 99002 is a fully threaded hex head cap screw designed for heavy-duty fastening applications. Manufactured from Grade 8 steel with a bright uncoated finish, it delivers high tensile strength suitable for structural and mechanical assemblies. The 1/4-20 UNC thread pattern and 3/4-inch length under head make it a standard fit for a wide range of bolted connections. Conforming to ASME B18.2.1 dimensional standards, this fastener is sold in a package quantity of 100, making it practical for shop stock, field kits, and production use. Installed by mechanics, millwrights, HVAC technicians, electricians, and plumbers in both residential and commercial settings.

This cap screw is suited for general mechanical assembly, equipment mounting, and structural fastening where a high-strength inch-series fastener is required. The 1/4-20 coarse thread is one of the most common thread forms in inch-based mechanical systems, making it broadly applicable across HVAC equipment panels, electrical enclosures, plumbing fixtures, and light structural frames. The bright uncoated finish is appropriate for indoor or protected environments where corrosion resistance is not the primary requirement. The pack of 100 supports both single-job use and ongoing maintenance inventory.

Installation Notes

Install with a standard hex wrench or socket driver sized for a 1/4-inch hex head cap screw. De-energize or shut down any equipment before fastener service on live electrical or mechanical systems. Apply fastener torque per the applicable equipment manufacturer specification or relevant industry standard for Grade 8 hardware. Inspect threads for damage before installation to ensure proper seating and clamp load.
