Holo-krome 72092 Hex Socket Cap Screw 1/4-20 Unc Alloy Steel

Product Description

The HOLO-KROME 72092 is a hex socket cap screw designed for demanding fastening applications where a low-profile, high-strength connection is required. Sized at 1/4-20 UNC with a 1/2-inch length under head, this fastener is fully threaded along its entire shank. The 3/16-inch hex drive socket accepts a standard hex key or Allen wrench. Manufactured from alloy steel with a black oxide finish, it meets ASME B18.3 and ASTM A574 standards, confirming mechanical strength suitable for industrial and mechanical assembly work. Machinists, maintenance technicians, and fabricators rely on this screw for machine building, fixture assembly, and equipment repair.

This socket cap screw suits a broad range of industrial, mechanical, and manufacturing applications where a recessed hex drive is preferred over an external hex head. The compact head profile allows installation in tight clearances where a standard bolt head would interfere. Fully threaded construction makes it well-suited for thin material assemblies or applications requiring engagement along the full length of the fastener. It is commonly used in machine frames, jigs, tooling fixtures, and general mechanical assemblies across shop and field environments.

Key Features

• 1/4-20 UNC thread size with fully threaded shank for maximum engagement
• 1/2-inch length under head suits thin-stock and short-depth tapped hole applications
• 3/16-inch hex socket drive accepts standard Allen keys and hex bit drivers
• Alloy steel construction meets ASTM A574 high-strength fastener requirements
• Black oxide finish provides mild corrosion resistance and reduces light reflection
• Conforms to ASME B18.3 dimensional standards for interchangeability and consistency

Compatibility

Designed as a standard 1/4-20 UNC hex socket cap screw conforming to ASME B18.3, compatible with any tapped or threaded hole sized for 1/4-20 UNC thread in industrial, mechanical, or fabrication assemblies.

Installation Notes

Install using a 3/16-inch hex key or hex bit driver rated for the torque required by the application. Ensure the mating tapped hole is clean and free of debris before threading. Do not exceed the recommended torque for 1/4-20 alloy steel fasteners as specified by the equipment manufacturer or applicable engineering standards. Black oxide finish is not a heavy corrosion barrier; apply supplemental coating or lubricant if the installation environment involves moisture or chemical exposure.
