Value Collection MS16997-62 Hex Socket Cap Screw 1/4-20

Product Description

The VALUE COLLECTION MS16997-62 is a fully threaded hex socket cap screw designed for secure fastening in mechanical assemblies, tooling fixtures, and structural applications. It features a 1/4-20 UNC thread size with a 1-inch length under the head, driven by a 3/16-inch hex socket. Constructed from alloy steel grade 4037 and finished with a yellow cadmium plating for corrosion resistance, this fastener meets ASME B18.3 dimensional standards. It is suited for applications where a recessed-drive, high-strength cap screw is required and space around the fastener head is limited.

This screw is appropriate for use in general industrial maintenance, machine assembly, and precision mechanical work. The yellow cadmium finish provides a degree of corrosion protection in moderate environments, making it a common choice in aerospace-adjacent, military, and industrial MRO applications. The fully threaded shank engages the full length of a tapped hole, which is useful in thinner or shorter threaded assemblies where partial threading would reduce grip. Installers in manufacturing, tooling, and equipment maintenance will encounter this fastener type in motor mounts, brackets, housings, and fixtures.

Key Features

• 1/4-20 UNC fully threaded shank provides maximum thread engagement across the full 1-inch length under head
• 3/16-inch hex socket drive allows installation with a standard hex key or Allen driver in tight clearance areas
• Alloy steel grade 4037 construction delivers higher tensile strength compared to standard carbon steel fasteners
• Yellow cadmium plating offers corrosion resistance in moderate-exposure environments
• Conforms to ASME B18.3 fastener standard for dimensional consistency and interchangeability

Compatibility

Designed as an OEM-style replacement or standard fitment hex socket cap screw for 1/4-20 UNC tapped hole applications per ASME B18.3.

Installation Notes

Installation is performed with a 3/16-inch hex key or socket driver. Ensure the mating tapped hole is clean and free of debris before threading the screw. Power down or de-energize any equipment before fastener service on live assemblies. Do not exceed the yield point of the alloy by over-torquing; consult the assembly engineering specifications for the applicable torque value for the specific joint material and application.
