Holo-krome 72094 Hex Socket Cap Screw 1/4-20 Unc Alloy Steel

Product Description

The HOLO-KROME 72094 is a hex socket cap screw designed for high-strength fastening applications requiring a recessed drive profile. Sized at 1/4-20 UNC with a 5/8-inch length under head, it is fully threaded along its entire shank. The 3/16-inch hex drive socket accepts a standard Allen key or hex bit driver. Constructed from alloy steel with a black oxide finish, this screw delivers corrosion resistance and a consistent surface treatment suited to demanding mechanical and industrial assemblies. It meets ASME B18.3 and ASTM A574 standards, confirming its dimensional accuracy and tensile strength requirements for socket cap fasteners.

This screw is used in mechanical assemblies, machine components, fixtures, and equipment enclosures where a low-profile, high-torque fastener is required. The socket cap head allows installation in counterbored or tight-access locations where a hex wrench can be inserted. Common installation environments include manufacturing equipment, conveyor systems, structural brackets, and general industrial hardware. This fastener is sold in minimum order quantities of 100 pieces, making it suitable for production assembly, maintenance stock, and job-lot sourcing.

Key Features

• 1/4-20 UNC thread for broad compatibility with standard imperial hardware
• 5/8-inch length under head, fully threaded for maximum thread engagement
• 3/16-inch hex socket drive accepts standard Allen keys and hex bit drivers
• Alloy steel construction meets ASTM A574 tensile strength requirements
• Black oxide finish provides moderate corrosion resistance and reduced light reflection
• Meets ASME B18.3 dimensional standard for socket cap screws

Compatibility

Designed as an OEM-style and general-use replacement hex socket cap screw for any assembly specifying a 1/4-20 UNC, 5/8-inch length under head, fully threaded socket cap screw conforming to ASME B18.3 and ASTM A574.

Installation Notes

Installation is performed with a 3/16-inch hex key or Allen driver; ensure the tool is fully seated in the socket before applying torque to avoid cam-out or drive damage. Confirm mating threads are clean and free of debris before driving. Where used in structural or load-bearing applications, consult applicable mechanical codes and the assembly specification for required fastener grade and torque values. Black oxide-finished fasteners are not suitable as a standalone corrosion barrier in wet or outdoor environments without additional lubrication or sealant.
