Value Collection D39060 Hex Head Cap Screw 3/8-16 X 2-1/2 in

Product Description

The VALUE COLLECTION D39060 is a Grade 8 steel hex head cap screw with a 3/8-16 UNC thread and a 2-1/2-inch length under head. It features a zinc yellow dichromate finish that provides corrosion resistance in demanding environments. The screw is partially threaded and conforms to ASME B18.2.1 dimensional standards. This fastener is suited for structural and mechanical assembly work where high tensile strength and reliable clamping force are required. Licensed trades and maintenance professionals rely on Grade 8 fasteners for heavy-duty bolted connections in equipment, fabrication, and industrial maintenance applications.

This hex head cap screw is used in a wide range of commercial and industrial applications, including equipment mounting, steel fabrication, and structural assemblies. The 3/8-16 UNC thread is a common size found in HVAC equipment frames, electrical enclosures, plumbing brackets, and general mechanical systems. Its partial threading allows for shank engagement in clearance holes, making it appropriate for standard through-bolt and fastened-joint configurations.

Key Features

• Grade 8 steel construction for high tensile and proof load strength
• Zinc yellow dichromate finish for corrosion and oxidation resistance
• Partially threaded shank per ASME B18.2.1 dimensional standard
• 3/8-16 UNC thread for broad compatibility with standard hex nuts and tapped holes
• 2-1/2-inch length under head suits medium-depth fastening applications

Compatibility

Designed for use with standard 3/8-16 UNC hex nuts, lock nuts, and tapped holes conforming to Unified National Coarse thread specifications.

Installation Notes

Installation is performed by qualified mechanics or tradespeople using a standard hex socket or open-end wrench sized to the 3/8-inch fastener head. Always de-energize and lock out equipment before performing fastener work on live systems. Follow applicable torque specifications from the equipment manufacturer or relevant standards for Grade 8 fasteners. Do not substitute a lower-grade fastener in applications specified for Grade 8.
