Value Collection 011447BR Hex Socket Cap Screw 5/8-18 Unf

Product Description

The VALUE COLLECTION 011447BR is a hex socket cap screw designed for high-strength fastening applications requiring precision thread engagement. With a 5/8-18 UNF thread size and a 1-inch length under head, this screw is fully threaded for maximum grip along the entire shank. The 1/2-inch hex drive socket head accepts standard hex keys and socket drive tools. Manufactured from alloy steel with a black oxide finish, it provides solid corrosion resistance in moderate environments. This fastener meets ASME/ANSI B18.3 and ASTM A574 standards, making it appropriate for structural and mechanical assemblies where rated fastener strength is required.

This screw is suited for mechanical, industrial, and structural applications where a recessed hex drive is needed to reduce interference with surrounding components. It is commonly installed in machine frames, equipment enclosures, tooling fixtures, and general fabrication work. Machinists, millwrights, and maintenance technicians regularly specify UNF-thread socket cap screws in this size range for fine-thread applications that demand tighter clamp loads than coarse-thread equivalents.

Key Features

• 5/8-18 UNF fine thread for increased clamp load and vibration resistance
• Fully threaded shank engages the full 1-inch length under head
• 1/2-inch hex socket drive accepts standard Allen keys and socket drive tools
• Alloy steel construction meets ASTM A574 mechanical requirements
• Black oxide finish provides moderate corrosion resistance and reduced light reflection
• Meets ASME/ANSI B18.3 dimensional standards

Compatibility

Designed as an OEM-style replacement or stock fastener for mechanical and industrial assemblies requiring 5/8-18 UNF hex socket cap screws conforming to ASME/ANSI B18.3 and ASTM A574 standards.

Installation Notes

Installation should be performed by a qualified machinist or maintenance technician using a calibrated torque wrench and the appropriate 1/2-inch hex key or socket bit. Clean and inspect the mating threaded hole before installation to ensure thread integrity. Apply thread lubricant or fastener compound as required by the assembly specification. Never exceed the rated torque for the fastener grade or the base material being threaded into.
