Value Collection D39083 Hex Head Cap Screw 7/16-14 X 2 in Grade 8

Product Description

The VALUE COLLECTION D39083 is a Grade 8 steel hex head cap screw with a 7/16-14 UNC thread and a 2-inch length under head. Partially threaded, it conforms to ASME B18.2.1 dimensional standards, making it a reliable fastener for high-strength bolted connections. The zinc yellow dichromate finish provides corrosion resistance suitable for general industrial and mechanical applications. This screw is used wherever a high-strength, inch-series fastener is required and is commonly installed by millwrights, maintenance technicians, pipefitters, and general contractors working with structural or mechanical assemblies.

This fastener is well suited for industrial maintenance, equipment assembly, and structural bolting applications where Grade 8 strength is specified. The partial threading allows for precise clamping without thread engagement in the grip zone, which is important in shear-load applications. Sold individually, this screw is available in multiples of 25 to support job-lot purchasing for production or maintenance shops.

Key Features

• Grade 8 steel construction meets high-strength fastener requirements for demanding mechanical applications
• 7/16-14 UNC thread form ensures broad compatibility with standard inch-series nuts and tapped holes
• Partially threaded shank provides a smooth grip zone for shear-load and close-tolerance bolted joints
• Zinc yellow dichromate finish delivers corrosion resistance for indoor and light-duty outdoor environments
• Conforms to ASME B18.2.1 for consistent dimensional accuracy across production and maintenance use

Compatibility

Designed for use with standard 7/16-14 UNC inch-series hex nuts, flat washers, and lock washers in Grade 8 or equivalent fastener assemblies.

Installation Notes

Installation should be performed by qualified mechanical or maintenance tradespeople using calibrated torque equipment appropriate for Grade 8 fasteners at this thread size. Always clean and inspect mating threads before installation to prevent galling or cross-threading. Do not exceed the rated proof load for the Grade 8 designation. Refer to applicable industry standards or equipment manufacturer torque specifications when final tightening values are required.
