Value Collection MS16997-102 Hex Socket Cap Screw 3/8-16

Product Description

The VALUE COLLECTION MS16997-102 is a hex socket cap screw designed for applications requiring precise torque and a flush, low-profile fastening solution. Manufactured from 4037 alloy steel with a yellow cadmium-plated finish, this screw offers corrosion resistance alongside the high tensile strength associated with alloy steel fasteners. It features a 3/8-16 UNC thread size, a 1-3/4 inch length under head, and a 5/16 inch hex drive. The partial threading design allows for controlled clamping force across a wide range of joint configurations. Conforming to ASME B18.3, this fastener meets recognized dimensional and performance standards for socket cap screws used in mechanical assembly, maintenance, and repair work.

This screw is suited for use in general mechanical assemblies, machine maintenance, and fabrication environments where a strong, recessed-drive fastener is required. The partially threaded shank provides a bearing surface that resists shear forces in bolted joints. Common applications include securing machine components, fixtures, tooling plates, and structural brackets in industrial and trade settings. Machinists, millwrights, and maintenance technicians are the primary installers. The yellow cadmium plating provides protection in moderately corrosive environments.

Key Features

• 3/8-16 UNC thread for broad compatibility with standard tapped holes
• 1-3/4 inch length under head with partial threading for shear-resistant clamping
• 5/16 inch hex socket drive for use with standard hex keys and T-handle drivers
• 4037 alloy steel construction for high tensile strength
• Yellow cadmium-plated finish for corrosion resistance in moderate service environments
• Manufactured to ASME B18.3 dimensional 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 fastener with a 5/16 inch hex drive.

Installation Notes

Installation should be performed by a qualified machinist or maintenance technician using a calibrated hex key or socket driver sized to 5/16 inch. Verify that the mating tapped hole is clean and free of debris before threading. Do not exceed the rated torque range for the 3/8-16 alloy steel grade; consult applicable engineering references for torque values specific to joint conditions. The yellow cadmium finish may be subject to handling and environmental regulations — follow applicable safety and disposal guidelines when working with cadmium-plated fasteners.
