Value Collection -33681-1 Hex Socket Cap Screw 5/8-11 Unc

Product Description

The VALUE COLLECTION -33681-1 is a hex socket cap screw engineered for high-strength fastening applications in industrial, mechanical, and maintenance environments. Built from alloy steel with a black oxide finish, this fastener delivers corrosion resistance and a clean appearance in demanding service conditions. It features a 5/8-11 UNC thread size with a 1-1/4 inch length under head and is fully threaded for maximum grip engagement. The 1/2 inch hex drive accommodates standard socket tooling. It conforms to ASME/ANSI B18.3 and ASTM A574 standards, making it suitable for structural and mechanical fastening work performed by machinists, millwrights, and maintenance technicians.

This cap screw is suited for general industrial assembly, fixture building, machine maintenance, and structural fastening where a recessed hex drive is preferred over an external hex head. The fully threaded design is ideal for through-hole and short-grip applications. It is ordered in multiples of 25, making it appropriate for shop stock, MRO inventory, and field service kits where consistent supply of standard fasteners is required.

Key Features

• 5/8-11 UNC thread size for compatibility with standard American coarse-thread tapped holes
• 1-1/4 inch length under head, fully threaded for maximum thread engagement
• 1/2 inch hex socket drive accepts standard socket drivers and hex keys
• Alloy steel construction meets ASTM A574 high-strength requirements
• Black oxide finish provides mild corrosion resistance and reduced light reflection
• 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 tapped hole or threaded insert with a 5/8-11 UNC thread form requiring a cap screw with 1-1/4 inch length under head.

Installation Notes

Installation is performed using a 1/2 inch hex key or socket driver. Ensure the mating threaded hole is clean and free of debris before installation. Do not exceed the rated torque range for alloy steel cap screws at this diameter; consult standard torque tables for ASTM A574 fasteners when specific torque values are required. De-energize and lock out any machinery before replacing or installing fasteners on powered equipment.
