Holo-krome 72206 Hex Socket Cap Screw 7/16-14 Unc

Product Description

The HOLO-KROME 72206 is a hex socket cap screw designed for high-strength fastening applications in industrial, mechanical, and trade settings. It features a 7/16-14 UNC thread and a 2-1/2-inch length under head with partial threading. The 3/8-inch hex drive accepts standard hex keys and Allen-type drivers. Constructed from alloy steel with a black oxide finish, it provides good corrosion resistance in controlled environments and meets ASME B18.3 and ASTM A574 standards. Machinists, millwrights, and maintenance technicians use this fastener when a recessed-drive, high-torque cap screw is required.

This screw is suited for use in machinery assemblies, equipment mounts, jigs, fixtures, and structural mechanical connections where a clean, low-profile socket head is preferred over a hex bolt. The partial threading is typical for applications requiring a bearing shank or where the grip length must remain unthreaded. It is a common fastener in industrial maintenance, OEM assembly, and field repair work across manufacturing, HVAC equipment frames, and mechanical support structures.

Key Features

• 7/16-14 UNC thread for reliable engagement with standard unified coarse-thread tapped holes
• 2-1/2-inch length under head with partial threading for shank-bearing applications
• 3/8-inch hex socket drive for use with standard Allen keys or hex bit drivers
• Alloy steel construction meets ASTM A574 high-strength socket screw requirements
• Black oxide finish provides mild corrosion resistance and reduces surface reflectivity
• Conforms to ASME B18.3 dimensional standard for socket cap screws

Compatibility

Designed as an OEM-style replacement or maintenance fastener for any application requiring a 7/16-14 UNC partially threaded hex socket cap screw conforming to ASME B18.3 and ASTM A574.

Installation Notes

Installation is typically performed by machinists, millwrights, or maintenance technicians using a 3/8-inch hex key or Allen-type bit driver. Ensure the mating tapped hole is clean and free of debris before installation. Always follow applicable torque specifications from your equipment manufacturer or relevant standards for 7/16-14 alloy steel fasteners. Do not exceed the rated drive engagement depth or apply impact tools without a rated hex socket bit.
