Value Collection 581707BR Hex Socket Cap Screw 3/4-10 Unc

Product Description

The VALUE COLLECTION 581707BR is a partially threaded hex socket cap screw designed for high-strength fastening applications in industrial, mechanical, and structural assemblies. It features a 3/4-10 UNC thread and measures 12 inches under the head, making it well suited for deep through-bolting and long-grip clamping tasks. The screw is driven with a 5/8-inch hex key. Manufactured from alloy steel with a black oxide finish, it delivers solid corrosion resistance and the tensile strength expected of ASME/ANSI B18.3 and ASTM A574 grade socket cap fasteners. Machinists, millwrights, and maintenance technicians are the typical installers.

This fastener is appropriate for heavy-duty bolted connections in manufacturing equipment, fixtures, machine frames, and structural jigs. The 3/4-10 UNC coarse thread pitch offers reliable engagement in tapped holes in steel, cast iron, and similar materials. Partial threading along the 12-inch shank allows for a smooth unthreaded grip length, which is useful when precise shear loading or close-tolerance alignment is required in the joint.

Key Features

• 3/4-10 UNC coarse thread for dependable thread engagement in tapped alloy and ferrous metal holes
• 12-inch length under head provides an extended grip for deep or stacked assemblies
• Partially threaded shank supports shear load applications and precise joint alignment
• Alloy steel construction meets ASTM A574 mechanical requirements for socket cap screws
• Black oxide finish provides mild corrosion resistance and reduces light reflection in service
• Driven with a 5/8-inch hex key — standard in most industrial tool sets

Compatibility

Designed as an OEM-style and aftermarket replacement hex socket cap screw for any application requiring a 3/4-10 UNC partially threaded socket cap fastener conforming to ASME/ANSI B18.3 and ASTM A574 standards.

Installation Notes

Installation should be performed by a qualified mechanic, machinist, or millwright using a properly sized 5/8-inch hex key or Allen-drive tool. Always verify the tapped hole depth and thread condition before installation, and ensure mating threads are clean and free of debris. De-energize, lock out, and tag out any equipment before fastener service. Do not use impact drivers on socket cap screws unless the driver is rated and sized for hex socket drive fasteners.
