Value Collection MS16997-99 Hex Socket Cap Screw 3/8-16

Product Description

The VALUE COLLECTION MS16997-99 is a hex socket cap screw designed for high-strength fastening applications in industrial, mechanical, and trade assembly work. It features a 3/8-16 UNC thread size with a 1-inch length under head and is fully threaded along its entire shank. The drive type is hex, accepting a 5/16-inch hex key. Constructed from 4037 grade alloy steel with a yellow cadmium-plated finish, this fastener delivers both corrosion resistance and the mechanical strength required for demanding service environments. It conforms to ASME B18.3 fastener standards. Licensed tradespeople and assembly technicians routinely specify this screw for structural and mechanical connections requiring reliable clamping force.

This fastener is suited for general industrial assembly, machine building, maintenance and repair operations, and trade fabrication work. The 3/8-16 UNC coarse thread pattern provides strong thread engagement in steel, cast iron, and other common base materials. The yellow cadmium coating offers corrosion protection in moderate-exposure environments. It is a practical choice wherever a standard hex socket cap screw of this thread size and length is called out in plans or specifications.

Key Features

• 3/8-16 UNC coarse thread for reliable engagement in common base materials
• 1-inch length under head, fully threaded shank for maximum thread engagement
• 5/16-inch hex drive — accepts standard hex keys and hex bit drivers
• 4037 alloy steel construction for high tensile strength
• Yellow cadmium-plated finish for corrosion resistance in moderate environments
• Conforms to ASME B18.3 fastener standard

Compatibility

Designed as a standard ASME B18.3 hex socket cap screw for use in tapped holes or with nuts calling for a 3/8-16 UNC thread specification in industrial and mechanical assemblies.

Installation Notes

Install using a 5/16-inch hex key or compatible hex bit driver. Ensure the receiving hole is properly tapped and free of debris before installation. Do not exceed the rated mechanical capacity of the fastener by applying excessive torque beyond what the application design specifies. Follow applicable industry standards and job specifications when installing in structural or pressure-bearing applications.
