Value Collection 011449BR Hex Socket Cap Screw 5/8-18 Unf

Product Description

The VALUE COLLECTION 011449BR is a hex socket cap screw designed for high-strength fastening applications in mechanical assemblies, tooling, and industrial equipment. Manufactured from alloy steel with a black oxide finish, this fastener delivers corrosion resistance and a clean, low-profile head. It features a 5/8-18 UNF thread — a fine-pitch thread suited for applications requiring tight clamping force and vibration resistance. The 1/2-inch internal hex drive accepts a standard hex key or Allen-drive socket. With a 1-1/4-inch length under head and fully threaded shank, this screw is well suited to through-hole and threaded-insert configurations. Compliant with ASME/ANSI B18.3 and ASTM A574 standards.

This cap screw is used in maintenance, repair, and original equipment manufacturing environments across metalworking, machinery, and fabrication shops. Its fine UNF thread pitch makes it a practical choice when assembling components that require precise torque control or where axial load resistance is critical. The black oxide coating reduces galling and light surface oxidation. Machinists, millwrights, and maintenance technicians are the primary installers. It is sold in a minimum order quantity of 10 units, with one piece per package.

Key Features

• 5/8-18 UNF fine-pitch thread for high clamping force and vibration resistance
• Fully threaded shank provides maximum thread engagement across the usable length
• Alloy steel construction meets ASTM A574 high-strength socket cap screw requirements
• Black oxide finish reduces surface corrosion and minimizes galling during installation
• 1/2-inch hex drive accepts standard hex keys and Allen-drive sockets
• Compliant with ASME/ANSI B18.3 dimensional standards

Compatibility

Designed as a standard ASME/ANSI B18.3 hex socket cap screw for use in any threaded bore or through-hole application requiring a 5/8-18 UNF fastener with a 1-1/4-inch length under head.

Installation Notes

Installation is performed by machinists, millwrights, or maintenance technicians using a calibrated torque wrench and a 1/2-inch hex key or Allen-drive bit. Ensure the mating threaded bore is clean and free of debris before installation. Apply thread lubricant or thread-locking compound only as specified by the equipment manufacturer. Do not exceed the rated torque for the fastener grade to avoid thread stripping or fastener failure.
