Value Collection D39058 Hex Head Cap Screw 3/8-16 X 2 in Grade 8

Product Description

The VALUE COLLECTION D39058 is a Grade 8 steel hex head cap screw with a 3/8-16 UNC thread and a 2-inch length under head. It features a zinc yellow dichromate finish that provides corrosion resistance in demanding environments. The screw is partially threaded and manufactured to ASME B18.2.1 standards, making it a reliable fastener for structural, mechanical, and industrial assembly applications. Installed by maintenance technicians, millwrights, and mechanical contractors, it is a standard inch-series fastener suitable wherever a high-strength 3/8-inch hex cap screw is specified.

This fastener is suited for heavy-duty bolted connections in general manufacturing, equipment assembly, and structural fabrication. Its Grade 8 rating indicates a minimum tensile strength of 150,000 psi class, making it appropriate for high-load, high-stress joint applications. The partial threading is standard for longer grip-length installations where the unthreaded shank bears shear load. It is sold in multiples of 25 units per order.

Key Features

• Grade 8 steel construction for high tensile strength in demanding bolted joints
• 3/8-16 UNC thread conforms to inch-series Unified National Coarse standard
• 2-inch length under head suits applications requiring extended grip length
• Partially threaded shank for improved shear load distribution
• Zinc yellow dichromate finish provides corrosion and oxidation resistance
• Manufactured to ASME B18.2.1 dimensional standards

Compatibility

Designed as a standard inch-series hex head cap screw for use in any application specifying a 3/8-16 UNC Grade 8 fastener with a 2-inch length under head and partial threading.

Installation Notes

Installation is performed by mechanics, millwrights, or maintenance technicians using a standard hex wrench or socket drive sized for a 3/8-inch hex cap screw. Always verify mating thread condition and material compatibility before installation. Follow applicable torque specifications from the equipment manufacturer or relevant industry standards for Grade 8 fasteners. Do not mix inch-series and metric fasteners in the same joint assembly.
