Value Collection 581715BR Hex Socket Cap Screw 3/4-10 Unc

Product Description

The VALUE COLLECTION 581715BR is a hex socket cap screw designed for high-strength fastening applications in mechanical assemblies, fixtures, and structural connections. Manufactured from alloy steel with a black oxide coating, it provides corrosion resistance and a consistent matte finish suited for industrial and trade environments. The screw features a 3/4-10 UNC thread, a 20-inch length under head, and a 5/8-inch hex drive socket. It is partially threaded, which is standard for long-body fasteners where clamping force and alignment are priorities. This fastener is installed by machinists, millwrights, and maintenance technicians in applications where socket-drive access is required.

This fastener is suited for use in industrial machinery, equipment frames, jigs, fixtures, and structural assemblies requiring a large-diameter, long-length socket cap screw. The 3/4-10 UNC coarse thread provides strong thread engagement in steel and iron tapped holes. The partial threading on a 20-inch body length makes it appropriate for through-bolt and long-clamp configurations common in heavy fabrication and maintenance work. It meets ASME/ANSI B18.3 and ASTM A574 standards, confirming dimensional and mechanical property compliance for alloy steel socket cap screws.

Key Features

• 3/4-10 UNC coarse thread for high clamping force and strong thread engagement
• 20-inch length under head accommodates deep through-bolt and long-clamp applications
• Partially threaded shank reduces stress concentrations and supports alignment in clearance holes
• 5/8-inch hex socket drive for use with standard hex keys and drive tooling
• Alloy steel construction with black oxide coating for strength and moderate corrosion resistance
• Meets ASME/ANSI B18.3 and ASTM A574 standards for dimensional and mechanical compliance

Compatibility

Designed as an OEM-style and aftermarket replacement socket cap screw for industrial machinery, fabrication, and maintenance applications requiring a 3/4-10 UNC, 20-inch partially threaded alloy steel fastener conforming to ASME/ANSI B18.3 and ASTM A574.

Installation Notes

Installation is performed by machinists, millwrights, or maintenance technicians using a 5/8-inch hex key or socket drive tool. Always de-energize and lock out equipment before installing or removing fasteners in mechanical assemblies. Verify that the tapped hole or nut meets the required thread class and material strength before torquing. Do not substitute thread lubricants or anti-seize compounds without confirming compatibility with the base material and application requirements.
