Value Collection 015441BR Hex Socket Cap Screw 5/8-18 Unf

Product Description

The VALUE COLLECTION 015441BR is a hex socket cap screw designed for high-strength fastening applications in mechanical assemblies, tooling, and industrial equipment. It features a 5/8-18 UNF thread size with a 1-1/4 inch length under head and is fully threaded for maximum thread engagement. The screw is manufactured from alloy steel with a black oxide finish for improved corrosion resistance and reduced light reflection. A 1/2-inch hex drive socket is required for installation. This fastener meets ASME/ANSI B18.3, ASTM A574, and IFI 124 standards, making it a reliable choice for precision and load-bearing applications.

This cap screw is suited for use in mechanical, manufacturing, and maintenance environments where a strong, compact fastener is needed. The socket cap head profile allows installation in confined spaces where a standard hex bolt head would not fit. Common applications include machine tooling fixtures, industrial equipment assembly, and structural fastening where fine-thread engagement and controlled torque are required. It is typically installed by machinists, maintenance technicians, or millwrights working with metal fabrication and mechanical systems.

Key Features

• 5/8-18 UNF fine thread for precise thread engagement and vibration resistance
• 1-1/4 inch length under head, fully threaded for maximum clamping range
• Alloy steel construction provides high tensile strength for demanding load applications
• Black oxide coating offers corrosion resistance and a low-reflectivity surface
• 1/2-inch hex socket drive for use with standard socket wrenches and hex keys
• Meets ASME/ANSI B18.3, ASTM A574, and IFI 124 fastener standards

Compatibility

Designed as a standard replacement or assembly fastener for applications requiring a 5/8-18 UNF hex socket cap screw with a 1-1/4 inch length under head and a 1/2-inch drive.

Installation Notes

Installation is performed by machinists, maintenance technicians, or millwrights using a calibrated torque wrench with a 1/2-inch hex socket bit. De-energize, depressurize, or lock out all equipment before fastener installation or removal per OSHA lockout/tagout procedures. Ensure mating threads are clean and free of debris before installation. Do not exceed the rated torque for the fastener grade and thread size as specified by the equipment manufacturer.
