Value Collection -33685-2 Hex Socket Cap Screw 5/8-11

Product Description

The VALUE COLLECTION -33685-2 is a hex socket cap screw designed for high-strength fastening applications in industrial, mechanical, and structural assemblies. Manufactured from alloy steel with a black oxide finish, this screw measures 2.75 inches under the head and is partially threaded with a 5/8-11 UNC thread form. The 0.5 inch hex drive socket accepts a standard hex key or Allen driver. Alloy steel construction provides high tensile strength, and the black oxide coating adds mild corrosion resistance while reducing light reflection. This fastener meets ASME/ANSI B18.3 and ASTM A574 standards. Sold individually with a minimum order quantity of 25 pieces.

This screw is suited for machine assembly, tool and die work, fixturing, and general mechanical fastening where a recessed drive and high clamp load are required. The partial threading allows the shank to bear shear loads, making it appropriate for close-tolerance bolt holes in steel, cast iron, and structural components. Commonly installed by machinists, maintenance technicians, and industrial assembly workers in manufacturing and maintenance environments.

Key Features

• 5/8-11 UNC thread size for high-load fastening applications
• 2.75 inch length under head with partial threading for shear-load capacity
• Alloy steel construction meets ASTM A574 high-strength requirements
• Black oxide finish provides mild corrosion resistance and reduced glare
• 0.5 inch hex socket drive compatible with standard hex keys and drivers
• Conforms to ASME/ANSI B18.3 dimensional standards

Compatibility

Designed as a standard ASME/ANSI B18.3 hex socket cap screw suitable for use in any application requiring a 5/8-11 UNC partially threaded fastener with a 0.5 inch hex drive.

Installation Notes

Installation requires a 0.5 inch hex key or Allen driver of appropriate length and quality rating for the torque demands of the application. Always ensure the mating threaded hole is clean and properly tapped to 5/8-11 UNC before installation. Power down or de-energize any equipment being serviced before accessing fastener locations in live assemblies. Do not substitute a lower-grade fastener in applications specified for ASTM A574 alloy steel hardware.
