Value Collection 581708BR Hex Socket Cap Screw 3/4-10 Unc

Product Description

The VALUE COLLECTION 581708BR is a partially threaded hex socket cap screw designed for high-strength fastening applications in industrial, mechanical, and structural assemblies. Sized at 3/4-10 UNC with a 13-inch length under head, this fastener is driven with a 5/8-inch hex key. Constructed from alloy steel with a black oxide finish, it delivers corrosion resistance and surface hardness suited to demanding service environments. It meets ASME/ANSI B18.3 and ASTM A574 standards, confirming dimensional accuracy and mechanical strength requirements expected in precision fastener applications.

This cap screw is suited for heavy-duty mechanical assemblies, machine tool fixtures, structural bolted joints, and equipment frames where a recessed drive head and high tensile strength are required. The partial threading allows for accurate clamping without thread engagement through the full grip length, making it appropriate for applications requiring controlled bearing load distribution. Maintenance technicians, millwrights, and mechanical contractors commonly install this fastener in both original equipment and field repair contexts.

Key Features

• 3/4-10 UNC thread form for standard coarse-thread engagement in steel components
• 13-inch length under head accommodates thick stack-ups and deep-grip fastening needs
• 5/8-inch hex socket drive for high-torque installation with standard hex keys or socket tooling
• Alloy steel construction provides high tensile and shear strength
• Black oxide finish adds mild corrosion resistance and reduces surface galling
• Meets ASME/ANSI B18.3 and ASTM A574 standards for dimensional and mechanical compliance

Compatibility

Designed as a standard 3/4-10 UNC hex socket cap screw suitable for any assembly specifying ASME/ANSI B18.3 or ASTM A574 compliant fasteners in this thread size and length.

Installation Notes

Installation should be performed by a qualified mechanic or millwright using a calibrated torque wrench and the appropriate 5/8-inch hex key or socket. De-energize and lock out all equipment before fastener installation or removal per applicable OSHA lockout/tagout procedures. Inspect mating threads for damage or contamination before assembly. Do not substitute a shorter or lower-grade fastener where this specification applies.
