Value Collection KP44097 Hex Cap Screw 9/16-12 X 2 in Grade 8

Product Description

The VALUE COLLECTION KP44097 is a fully threaded hex head cap screw designed for high-strength fastening applications. Built to Grade 8 steel specifications and compliant with ASTM A354 BD, this screw delivers the tensile strength required in demanding structural and mechanical assemblies. The 9/16-12 UNC thread pattern provides a coarse-thread profile suited for steel-to-steel connections, thick-stock materials, and applications where vibration resistance matters. A zinc-plated finish offers a baseline level of corrosion protection for indoor and sheltered installations. Each package contains 25 screws. Licensed tradespeople and maintenance technicians working in HVAC equipment, plumbing infrastructure, and electrical panel framing routinely specify Grade 8 fasteners where standard hardware-grade bolts fall short.

This screw is appropriate for residential and light commercial mechanical installations where high-clamping-force fasteners are required. Common applications include equipment mounting frames, structural steel connections, machinery bases, and trade-service brackets. The fully threaded shank allows maximum thread engagement across the full 2-inch length under head, making it well suited for thin-material stack-ups or where a nut must be positioned anywhere along the shank. HVAC equipment mounting, electrical enclosure assembly, and plumbing support structures are all typical use scenarios.

Key Features

• Grade 8 steel construction meets ASTM A354 BD for high tensile and proof-load strength
• Fully threaded 9/16-12 UNC shank across the full 2-inch length under head
• Zinc-plated finish provides corrosion resistance in sheltered or indoor environments
• Coarse UNC thread form for fast engagement and reliable clamping in steel assemblies
• Sold in a 25-count package with a minimum order quantity of 1 package

Compatibility

Designed as a standard 9/16-12 UNC Grade 8 hex head cap screw compatible with any application requiring ASTM A354 BD fasteners at this thread size and length.

Installation Notes

Installation is performed by qualified tradespeople using a standard hex socket or open-end wrench sized for a 9/16-12 fastener head. De-energize and lock out all electrical circuits before fastening within or near energized enclosures, following NFPA 70E safe work practices. Do not mix Grade 8 fasteners with lower-grade nuts or threaded inserts, as mismatched hardware grades reduce the rated joint strength. Inspect threads for damage before installation and discard any fastener with crossed or deformed threads.
