Value Collection MS16997-38 Hex Socket Cap Screw 8-32 Unc

Product Description

The VALUE COLLECTION MS16997-38 is a hex socket cap screw designed for secure fastening in mechanical assemblies requiring precise thread engagement and a low-profile head. Sized at 8-32 UNC with a 1-1/2 inch length under the head, this screw is partially threaded and accepts a 9/64 inch hex drive. Constructed from alloy steel grade 4037 with a yellow cadmium-plated finish, it offers corrosion resistance alongside the high tensile strength expected from alloy steel fasteners. Manufactured to ASME B18.3 standards, it is appropriate for use in machinery, fixtures, and precision mechanical components where dimensional consistency is critical.

This screw is suited for industrial, MRO, and OEM applications across manufacturing, equipment maintenance, and mechanical assembly environments. The 8-32 UNC thread size is a common machine screw thread used in light to medium-duty applications. The yellow cadmium plating provides corrosion protection and is recognizable by its characteristic iridescent yellow finish. It is typically installed by machinists, millwrights, and maintenance technicians working on metal fabrication, fixtures, and precision machinery.

Key Features

• 8-32 UNC thread size with 1-1/2 inch length under head for consistent fit in standard tapped holes
• Alloy steel grade 4037 construction provides high tensile strength
• Yellow cadmium-plated finish for corrosion resistance
• 9/64 inch hex socket drive for use with standard hex keys or Allen drivers
• Partially threaded shank allows for load-bearing shoulder applications
• Conforms to ASME B18.3 fastener standard for dimensional accuracy

Compatibility

Designed as an OEM-style replacement or standard-use hex socket cap screw for any application requiring an 8-32 UNC partially threaded screw with a 1-1/2 inch length under head, conforming to ASME B18.3.

Installation Notes

Installation is performed with a 9/64 inch hex key or matching Allen driver. Verify that the receiving tapped hole is clean and properly threaded to 8-32 UNC specification before driving the fastener. Power down and de-energize any equipment before performing fastener installation or removal on live assemblies. Do not over-torque; consult applicable engineering specifications or ASME standards for torque guidance specific to your application.
