Value Collection D39070 Hex Head Cap Screw 3/8-16 X 6 in

Product Description

The VALUE COLLECTION D39070 is a Grade 8 steel hex head cap screw with a 3/8-16 UNC thread and a 6-inch length under head. Partially threaded, it is built to ASME B18.2.1 dimensional standards, making it a reliable choice for high-strength fastening applications. The zinc yellow dichromate finish provides corrosion resistance suitable for general industrial and mechanical assemblies. This fastener is installed by maintenance technicians, millwrights, and general tradespeople wherever a strong, dependable bolted connection is required.

This cap screw is suited for structural and mechanical assemblies in industrial, commercial, and trade settings. The 3/8-16 UNC thread pattern is a widely used coarse-thread size compatible with standard hex nuts and threaded plates. Partial threading is appropriate for clamping applications where the shank must bear load across a joint without thread engagement through the full grip length.

Key Features

• Grade 8 steel construction for high tensile and proof load strength
• 3/8-16 UNC coarse thread for broad hardware compatibility
• 6-inch length under head suits longer grip applications
• Partially threaded shank for proper clamping in structural joints
• Zinc yellow dichromate finish provides corrosion and abrasion resistance
• Manufactured to ASME B18.2.1 dimensional standards

Compatibility

Designed as a standard 3/8-16 UNC hex head cap screw for use with matching 3/8-16 hex nuts, flat washers, and threaded fastener hardware in general industrial and mechanical assembly applications.

Installation Notes

Installation is performed with a standard hex wrench or socket set sized for a 3/8-16 hex head fastener. Ensure mating threads and seating surfaces are clean and free of debris before installation. Do not exceed the rated proof load for Grade 8 fasteners; consult applicable structural or mechanical specifications for proper torque values. Replace any fastener showing signs of thread damage, corrosion, or deformation.
