Value Collection MS16997-104 Hex Socket Cap Screw 3/8-16

Product Description

The VALUE COLLECTION MS16997-104 is a partially threaded hex socket cap screw designed for high-strength fastening applications in industrial, mechanical, and trade environments. It features a 3/8-16 UNC thread size and measures 2.25 inches under the head, making it well suited for medium-depth fastening into tapped holes. The drive is a 5/16-inch internal hex socket, requiring an Allen key or hex bit driver for installation. Manufactured from 4037 alloy steel with a yellow cadmium plating, this fastener delivers solid corrosion resistance alongside the tensile strength expected of alloy-grade hardware. It meets ASME B18.3 fastener standards.

This screw is appropriate for use in machinery assembly, structural bracketing, and mechanical equipment maintenance where a recessed-drive, high-strength fastener is required. The partial threading allows for clamping force across unthreaded shanks, which is advantageous when joining two or more components with a threaded receiving hole. Typically installed by millwrights, maintenance technicians, and general trade professionals working on industrial equipment, conveyors, frames, and similar assemblies.

Key Features

• 3/8-16 UNC thread size for compatibility with standard coarse-thread tapped holes
• 2.25-inch length under head for medium-depth fastening applications
• 5/16-inch hex socket drive for secure tool engagement and high torque transfer
• Partially threaded shank provides effective clamping across unthreaded material
• 4037 alloy steel construction for elevated tensile and shear strength
• Yellow cadmium plating provides corrosion and oxidation resistance
• Meets ASME B18.3 fastener standard

Compatibility

Designed as an OEM-style replacement or standard-fit fastener for applications requiring a 3/8-16 UNC partially threaded hex socket cap screw conforming to ASME B18.3 specifications.

Installation Notes

Installation requires a 5/16-inch hex key or socket bit driver rated for the torque demands of 4037 alloy steel fasteners. Ensure the receiving tapped hole is clean and free of debris before threading. Do not exceed the rated toque capacity of the fastener or the mating material. Follow applicable industry standards and equipment manufacturer guidelines when specifying fastener torque.
