Value Collection 581698BR Hex Socket Cap Screw 3/4-10 Unc

Product Description

The VALUE COLLECTION 581698BR is a hex socket cap screw sized 3/4-10 UNC with a 4-3/4 inch length under head. It features a 5/8 inch hex drive and a partial thread configuration. Manufactured from alloy steel and finished with a black oxide coating, this fastener meets ASME/ANSI B18.3 and ASTM A574 standards. Black oxide provides mild corrosion resistance and reduces light glare in service environments. This screw is suited for high-strength fastening applications in mechanical assemblies, machinery, tooling fixtures, and structural components where a recessed drive and controlled torque are required.

This fastener is commonly used in industrial maintenance, machine building, and fabrication environments. The 3/4-10 UNC coarse thread is a widely specified thread form in North American mechanical and structural assemblies. The partial threading allows the unthreaded shank to act as a precision locating surface, making it well suited for applications where alignment, shear load transfer, or close-tolerance fits are priorities. Machinists, millwrights, and industrial mechanics routinely install this type of fastener.

Key Features

• 3/4-10 UNC coarse thread for broad compatibility with standard tapped holes
• 4-3/4 inch length under head accommodates thick material stacks
• 5/8 inch hex socket drive for high-torque installation with standard Allen or hex keys
• Partially threaded shank for precision fit and shear load capability
• Alloy steel construction meets ASTM A574 high-strength requirements
• Black oxide finish for mild corrosion resistance and reduced reflectivity

Compatibility

Designed as a standard ASME/ANSI B18.3 hex socket cap screw for use in any tapped through-hole or blind hole sized for 3/4-10 UNC thread in industrial, mechanical, and structural applications.

Installation Notes

Installation is performed by machinists, millwrights, or maintenance mechanics using a 5/8 inch hex key or socket drive tool. Ensure the mating tapped hole is clean and correctly sized for 3/4-10 UNC before installation. De-energize and lockout any machinery before servicing fasteners on moving assemblies. Apply a thread lubricant or anti-seize compound appropriate to the service environment to achieve accurate torque values during installation.
