Value Collection 581713BR Hex Socket Cap Screw 3/4-10 Unc

Product Description

The VALUE COLLECTION 581713BR is a hex socket cap screw designed for high-strength fastening applications in industrial, mechanical, and structural assemblies. It features a 3/4-10 UNC thread size with an 18-inch length under the head and is partially threaded along the shank. The drive is a 5/8-inch internal hex socket, accepting a standard hex key or Allen-type driver. Constructed from alloy steel with a black oxide finish coating, this screw delivers solid tensile strength and mild corrosion resistance in controlled environments. It conforms to ASME/ANSI B18.3 and ASTM A574 standards, making it a recognized fastener choice for engineered assemblies.

This screw is suited for use in machinery, equipment frames, jigs, fixtures, and heavy fabrication where a recessed-drive cap screw with a long grip length is required. The partial threading provides a smooth shank section that offers precise location and shear resistance in bolted joints. Typical installers include machinists, millwrights, maintenance technicians, and structural fabricators working in industrial or commercial settings.

Key Features

• 3/4-10 UNC thread for compatibility with standard inch-series tapped holes
• 18-inch length under head provides extended grip for deep or stacked assemblies
• Partially threaded shank improves shear resistance and joint alignment
• 5/8-inch hex socket drive for use with hex keys or socket-drive tools
• Alloy steel construction meets ASTM A574 high-strength fastener requirements
• Black oxide finish provides mild corrosion resistance and reduces light reflection

Compatibility

Designed as an OEM-style replacement or standard-service fastener for industrial assemblies requiring a 3/4-10 UNC hex socket cap screw with an 18-inch length under head conforming to ASME/ANSI B18.3 and ASTM A574.

Installation Notes

Installation should be performed by a qualified machinist or mechanical technician using a properly sized 5/8-inch hex key or driver. De-energize and lock out any equipment before installing or removing fasteners in powered assemblies. Apply a thread lubricant or anti-seize compound appropriate for alloy steel if specified by the equipment manufacturer. Do not exceed the tensile ratings defined in ASTM A574 for the fastener grade.
