Value Collection 015477BR Hex Socket Cap Screw 3/4-10 Unc

Product Description

The VALUE COLLECTION 015477BR is a partially threaded hex socket cap screw engineered for high-strength fastening applications. It features a 3/4-10 UNC thread size and measures 3-1/2 inches in length under the head, driven with a 5/8-inch hex socket. Constructed from alloy steel with a black oxide finish, this fastener delivers solid mechanical strength with basic corrosion resistance. It conforms to ASME/ANSI B18.3, ASTM A574, and IFI 124 standards, making it suitable for applications where dimensional and mechanical compliance is required. Licensed trades and industrial assemblers rely on this style of cap screw in structural and mechanical assemblies where a recessed drive and high clamp load are priorities.

This hex socket cap screw is used across a wide range of mechanical, industrial, and structural applications. The socket head profile allows installation in confined spaces where a wrench cannot swing freely, making it a common choice in machinery, equipment frames, and fabricated assemblies. The partial threading provides full thread engagement in standard-depth tapped holes while leaving a smooth shank in the grip zone for shear-load scenarios. It is equally at home in light manufacturing, maintenance and repair operations, and field installation work.

Key Features

• 3/4-10 UNC thread size with partial threading for optimal grip-zone shank length
• 3-1/2 inches length under head for deep-reach fastening applications
• 5/8-inch hex socket drive for high-torque installation with a standard Allen or hex socket tool
• Alloy steel construction provides high tensile and yield strength
• Black oxide finish offers mild corrosion resistance and reduces surface glare
• Meets ASME/ANSI B18.3, ASTM A574, and IFI 124 standards

Compatibility

Designed as a standard 3/4-10 UNC hex socket cap screw suitable for tapped holes conforming to UNC thread specifications in machinery, structural steel, and equipment assemblies.

Installation Notes

Installation is typically performed by machinists, millwrights, pipefitters, or general mechanical trades using a 5/8-inch hex key or socket driver. Ensure the mating tapped hole is clean, properly sized, and free of debris before threading. Apply appropriate thread lubricant or anti-seize compound based on the service environment and material of the mating part. Do not exceed the rated fastener torque for the alloy steel grade and thread size as specified in applicable engineering references.
