Value Collection KP44039 3/8-16 X 3/4 in Grade 8 Hex Cap Screw

Product Description

The VALUE COLLECTION KP44039 is a fully threaded hex head cap screw designed for high-strength fastening applications in mechanical, structural, and industrial assemblies. Manufactured from Grade 8 steel and finished with a zinc plating for corrosion resistance, this fastener meets ASTM A354 BD standards, making it suitable for demanding load-bearing connections. The 3/8-16 UNC thread pattern and 3/4-inch length under head provide reliable clamping force in both original-equipment and field-repair contexts. Sold in a package of 100, this screw is appropriate for shops, service fleets, and trade contractors who need consistent, code-grade hardware on hand.

This fastener is used across a wide range of trade applications including HVAC equipment mounting, plumbing fixture framing, electrical panel support structures, and general mechanical assembly. The UNC thread form is compatible with standard tapped holes and nuts in inch-based systems. Grade 8 strength makes it appropriate where higher tensile loads are expected compared to Grade 5 or Grade 2 alternatives. The zinc plating provides mild corrosion protection suitable for indoor and sheltered outdoor environments.

Key Features

• Grade 8 steel construction for high tensile and proof load strength
• Zinc-plated finish provides corrosion resistance in typical service environments
• Fully threaded along the shank for maximum thread engagement in short-grip applications
• 3/8-16 UNC thread standard for compatibility with standard inch-series nuts and tapped holes
• Meets ASTM A354 BD specification for alloy and medium carbon steel fasteners
• Packaged in quantities of 100 for shop stock and field service use

Compatibility

Designed for use in standard inch-based assemblies requiring a 3/8-16 UNC thread pattern and a 3/4-inch grip length, consistent with typical hex head cap screw applications in mechanical and structural work.

Installation Notes

Installation is performed by qualified tradespeople using a standard 9/16-inch hex wrench or socket driver. Verify that mating threads and tapped holes are clean and free of debris before installation. Follow applicable torque guidelines from the fastener manufacturer or relevant standards such as ASME B18.2.1 for the specific joint design. Do not mix Grade 8 fasteners with lower-grade nuts, as mismatched hardware can compromise joint integrity.
