Value Collection 011423BR Hex Socket Cap Screw 5/8-11 Unc

Product Description

The Value Collection 011423BR is a hex socket cap screw designed for high-strength fastening in mechanical assemblies, machinery, and structural applications. It features a 5/8-11 UNC thread size with a 2-3/4 inch length under the head and is partially threaded to allow for controlled clamping in precision fits. The screw is manufactured from alloy steel with a black oxide finish, providing corrosion resistance and a clean, low-reflectance appearance. The 1/2 inch hex drive allows installation with standard hex keys or socket drivers. This fastener meets ASME/ANSI B18.3 and ASTM A574 standards, making it suitable for demanding industrial and maintenance applications.

This socket cap screw is suited for use in machine frames, fixture plates, tooling setups, and equipment assemblies where a low-profile head and high tensile strength are required. It is commonly installed by machinists, millwrights, maintenance mechanics, and industrial assemblers in both light and heavy manufacturing environments. The partial threading makes it appropriate for applications requiring a shoulder-style grip or where through-clearance holes are involved.

Key Features

• 5/8-11 UNC thread size for use in standard inch-series tapped holes
• 2-3/4 inch length under head, partially threaded for controlled clamping
• Alloy steel construction meets ASTM A574 for high tensile strength
• Black oxide finish provides mild corrosion resistance and low-glare surface
• 1/2 inch hex drive for installation with hex keys or socket wrenches
• Conforms to ASME/ANSI B18.3 dimensional standards

Compatibility

Designed as a standard inch-series hex socket cap screw for use in any 5/8-11 UNC tapped hole requiring a partially threaded alloy steel fastener per ASME/ANSI B18.3 and ASTM A574 specifications.

Installation Notes

Install using a calibrated 1/2 inch hex key or socket driver. Ensure the mating tapped hole meets 5/8-11 UNC thread specifications and is clean and free of debris before driving the fastener. Apply appropriate thread-locking compound or lubrication per the assembly specification. De-energize and lock out any equipment before performing fastener installation or removal on live machinery.
