Value Collection MS16997-103 Hex Socket Cap Screw 3/8-16

Product Description

The VALUE COLLECTION MS16997-103 is a hex socket cap screw engineered for fastening applications that demand precision threading and a secure, recessed drive. Built to ASME B18.3 standards, this screw features a 3/8-16 UNC thread size, a 2-inch length under the head, and a 5/16-inch hex drive. It is partially threaded, which is typical for clamping applications where thread engagement is required only through the joined material. Constructed from 4037-grade alloy steel with a yellow cadmium-plated finish, it offers corrosion resistance and high tensile strength suitable for mechanical assemblies and industrial maintenance work.

This fastener is suited for general mechanical, industrial, and maintenance-of-equipment applications where a recessed hex drive and partial threading are specified. The yellow cadmium coating provides additional corrosion protection in moderately demanding environments. It is commonly used by millwrights, maintenance mechanics, and field technicians assembling brackets, housings, flanges, and structural components that call for ASME B18.3-compliant socket head fasteners.

Key Features

• 3/8-16 UNC thread size for broad compatibility with standard tapped holes
• Partially threaded shank for positive clamping and bearing load distribution
• 5/16-inch hex socket drive for Allen wrench or hex key installation
• 4037-grade alloy steel construction for high tensile and shear strength
• Yellow cadmium-plated finish for corrosion resistance
• Manufactured to ASME B18.3 fastener standard

Compatibility

Designed as a standard ASME B18.3 hex socket cap screw for use in any application requiring a 3/8-16 UNC partially threaded socket head cap screw with a 2-inch length under head.

Installation Notes

Installation requires a 5/16-inch hex key or Allen driver. Ensure the mating tapped hole meets 3/8-16 UNC thread specifications before installation. Power down or de-energize any equipment before servicing fastened assemblies. Do not exceed the rated torque range for the alloy steel grade or substitute this fastener in safety-critical structural applications without verifying engineering specifications.
