Value Collection MS16997-51 Hex Socket Cap Screw 10-24

Product Description

The VALUE COLLECTION MS16997-51 is a hex socket cap screw engineered for secure, high-torque fastening in mechanical assemblies requiring precise thread engagement. The screw features a 10-24 UNC thread size with 1-3/4 inches of length under the head and a 5/32-inch hex drive. Constructed from 4037-grade alloy steel and finished with a yellow cadmium plating, it delivers solid corrosion resistance and mechanical strength in demanding service environments. This fastener conforms to ASME B18.3 standards and is partially threaded, which supports clamping force in through-bolt and clearance-hole applications.

This cap screw is suited for use in industrial, mechanical, and maintenance applications where a recessed hex drive is required for torque-sensitive installations. The yellow cadmium coating provides protection against oxidation and mild corrosion exposure. Typical applications include machinery assembly, fixtures, tooling, and equipment maintenance in manufacturing or trade settings. Installation is performed using a standard 5/32-inch hex key or Allen driver, making it compatible with common hand tools and torque drivers used by machinists, millwrights, and maintenance technicians.

Key Features

• 10-24 UNC thread form for compatibility with standard inch-series tapped holes
• 1-3/4 inches length under head with partial threading for proper clamping in clearance applications
• 5/32-inch hex socket drive for recessed installation with a hex key or torque driver
• 4037-grade alloy steel construction for high tensile strength
• Yellow cadmium plating provides corrosion and oxidation resistance
• Conforms to ASME B18.3 fastener standard

Compatibility

Designed as an OEM-style replacement or direct-fit fastener for applications requiring a 10-24 UNC hex socket cap screw per ASME B18.3 specifications.

Installation Notes

Installation is typically performed by machinists, millwrights, or maintenance technicians using a 5/32-inch hex key or torque driver. Ensure the mating tapped hole is clean, free of debris, and properly threaded to 10-24 UNC before installation. De-energize and lock out all equipment before replacing fasteners on active machinery. Do not substitute a metric hex key, as improper drive fit can damage the socket recess.
