Value Collection 011451BR Hex Socket Cap Screw 5/8-18 Unf

Product Description

The VALUE COLLECTION 011451BR is a hex socket cap screw designed for high-strength fastening applications in mechanical assemblies, tooling, and structural connections. It features a 5/8-18 UNF thread size with a 1-1/2 inch length under head and is fully threaded from head to tip. The alloy steel construction is finished with a black oxide coating, which provides mild corrosion resistance and reduces light reflection in service environments. The 1/2 inch hex drive accepts standard hex keys and socket drive tools. This fastener meets ASME/ANSI B18.3 and ASTM A574 standards, making it appropriate for load-bearing and precision-fit applications where dimensional consistency matters.

This cap screw is suited for use in machinery, fixtures, dies, and general metalworking assemblies where a flush or recessed fastener head is required. The fine 18 TPI thread pitch gives it excellent holding power and resistance to loosening under vibration, which makes it a common choice in equipment maintenance, manufacturing, and fabrication shops. Machinists, millwrights, and maintenance technicians are the primary installers. It is sold in multiples of 10.

Key Features

• 5/8-18 UNF fine thread for strong clamping force and vibration resistance
• Fully threaded along the 1-1/2 inch length under head
• Alloy steel construction meets ASTM A574 high-strength requirements
• Black oxide finish for mild corrosion protection and reduced surface reflectivity
• 1/2 inch hex socket drive compatible with standard hex keys and socket tools
• Conforms to ASME/ANSI B18.3 dimensional standards

Compatibility

Designed as a standard ASME/ANSI B18.3 hex socket cap screw for use in any application requiring a 5/8-18 UNF fully threaded alloy steel fastener with a 1/2 inch hex drive.

Installation Notes

Installation is performed with a 1/2 inch hex key or socket drive tool. Ensure the mating threaded hole is clean and free of debris before driving the fastener. Do not exceed the rated torque range for the fastener grade and material being clamped. Black oxide finish is not a heavy corrosion barrier; apply thread lubricant or anti-seize in wet or outdoor environments as appropriate for the application.
