Value Collection D39064 Hex Head Cap Screw 3/8-16 X 3.5 in Grade 8

Product Description

The Value Collection D39064 is a partially threaded hex head cap screw manufactured from Grade 8 steel with a zinc yellow dichromate finish. It features a 3/8-16 UNC thread and measures 3.5 inches under the head. Grade 8 steel provides high tensile strength suited for demanding fastening applications where standard-grade hardware is not adequate. The zinc yellow dichromate coating adds corrosion resistance. This fastener conforms to ASME B18.2.1 dimensional standards and is installed by millwrights, maintenance technicians, and mechanical contractors across industrial and commercial settings.

This cap screw is well suited for structural and mechanical assemblies where high-strength fasteners are required. Typical applications include machinery mounting, equipment frames, brackets, and heavy-duty fixture work. The partial threading allows the unthreaded shank to bear shear loads, making it appropriate for joints where load distribution across the grip length matters. It is a common replacement or stock fastener in maintenance, repair, and operations (MRO) environments.

Key Features

• Grade 8 steel construction for high tensile and proof load strength
• Zinc yellow dichromate finish provides corrosion resistance
• Partially threaded shank supports shear load applications
• 3/8-16 UNC thread form for compatibility with standard inch-series nuts and tapped holes
• Conforms to ASME B18.2.1 dimensional standards

Compatibility

Designed as a standard inch-series hex head cap screw for use with 3/8-16 UNC tapped holes and nuts in industrial, commercial, and mechanical assembly applications.

Installation Notes

Installation is performed by qualified mechanics or maintenance technicians using a standard hex wrench or socket driver sized for a 3/8-16 fastener. De-energize and isolate any equipment before fastening into powered machinery or structural assemblies. Do not exceed the torque rating specified by the equipment manufacturer or applicable fastener engineering standards for Grade 8 hardware. Inspect threads on both the fastener and the mating part for damage before installation.
