Value Collection MPKP44039 Hex Cap Screw 3/8-16 X 3/4 in Grade 8

Product Description

The VALUE COLLECTION MPKP44039 is a fully threaded hex head cap screw designed for high-strength fastening applications in mechanical, structural, and equipment assembly work. Built from Grade 8 steel with a zinc-plated finish, this screw meets ASTM A354 BD standards, making it suitable for demanding load-bearing connections. The 3/8-16 UNC thread size and 3/4-inch length under head are among the most common fastener dimensions used in trade and industrial settings. Each package contains 25 pieces, supporting small repairs and larger assembly jobs alike. Machinists, millwrights, pipefitters, and general contractors routinely reach for Grade 8 fasteners where standard hardware-grade screws are not adequate.

This cap screw is well suited for use in HVAC equipment frames, pump and motor mounts, structural brackets, and general mechanical assemblies where a high-strength, inch-series fastener is required. The 3/8-16 UNC thread is compatible with standard tapped holes and hex nuts of the same specification. The zinc plating provides a base level of corrosion resistance for indoor and light-duty outdoor installations. The fully threaded shank allows for maximum thread engagement across the full usable length of the fastener.

Key Features

• Grade 8 steel construction meets ASTM A354 BD for high-strength applications
• 3/8-16 UNC thread with 3/4-inch length under head for precise fit in standard tapped assemblies
• Fully threaded shank provides maximum thread engagement along the entire fastener length
• Zinc-plated finish offers basic corrosion resistance for general indoor and light outdoor use
• Pack of 25 pieces supports single repairs and multi-fastener assembly jobs

Compatibility

Designed as a standard inch-series hex head cap screw compatible with any 3/8-16 UNC tapped hole or matching hex nut in equipment frames, structural connections, and mechanical assemblies.

Installation Notes

Installation is typically performed by machinists, millwrights, pipefitters, or maintenance technicians using a standard hex wrench or socket set. Always de-energize and lock out equipment before replacing fasteners on live machinery. Follow applicable torque specifications for Grade 8 hardware as defined in the job specification or equipment manual. Inspect mating threads for damage or contamination before installation to ensure full thread engagement.
