Value Collection MS16997-97 Hex Socket Cap Screw 3/8-16

Product Description

The VALUE COLLECTION MS16997-97 is a hex socket cap screw designed for high-strength fastening applications in mechanical, industrial, and maintenance assemblies. Manufactured from 4037 alloy steel with a yellow cadmium-plated finish, this fastener delivers solid corrosion resistance and reliable clamping force in demanding environments. The screw features a 3/8-16 UNC thread size, a 3/4-inch length under head, and is fully threaded from head to tip, allowing engagement along the entire shank. Drive is accomplished with a 5/16-inch hex key. This fastener meets ASME B18.3 dimensional standards and is appropriate for use by maintenance technicians, millwrights, and industrial tradespeople requiring a dependable, specification-grade socket cap screw.

This screw is suited for general mechanical assemblies, equipment maintenance, and structural fastening tasks where a recessed hex drive is preferred for torque control and flush or countersunk head seating. The fully threaded design makes it particularly useful in through-hole and tapped-hole applications where maximum thread engagement along the full grip length is required. The yellow cadmium plating provides a degree of corrosion and wear resistance appropriate for light industrial and indoor mechanical environments.

Key Features

• 3/8-16 UNC thread size for standard inch-series tapped hole compatibility
• Fully threaded shank provides maximum thread engagement in tapped holes
• 4037 alloy steel construction for higher tensile strength compared to standard carbon steel
• Yellow cadmium-plated finish for corrosion and wear resistance
• 5/16-inch hex socket drive for precise torque application with a standard hex key or Allen wrench
• Meets ASME B18.3 dimensional standard for interchangeability and specification compliance

Compatibility

Designed as a specification-grade replacement or stocking fastener for any application requiring a 3/8-16 UNC fully threaded hex socket cap screw conforming to ASME B18.3.

Installation Notes

Installation is performed with a 5/16-inch hex key or socket driver. Ensure the mating tapped hole is clean and free of debris before threading the fastener. Apply appropriate thread lubricant or anti-seize compound as required by the assembly specification. Do not exceed the rated torque for the fastener grade and do not use an impact driver without a torque-limiting mechanism, as overdriving can damage the socket head or strip the tapped thread.
