Value Collection 581710BR Hex Socket Cap Screw 3/4-10 Unc

Product Description

The VALUE COLLECTION 581710BR is a hex socket cap screw designed for high-strength fastening applications in mechanical assemblies, industrial equipment, and structural components. Manufactured from alloy steel with a black oxide coating, this fastener measures 15 inches in length under the head and uses a 5/8-inch hex drive. The 3/4-10 UNC thread specification indicates a coarse-thread form with a nominal 3/4-inch diameter, making it suitable for applications that require substantial clamping force and resistance to loosening under vibration. It is partially threaded, which helps distribute load along the shank in through-bolt and heavy-duty clamping configurations.

This screw is used in industrial maintenance, machinery assembly, fabrication shops, and heavy equipment repair where high-tensile socket cap screws are specified. The 15-inch length under head accommodates thick plate assemblies, deep counterbored holes, and long-reach clamping needs. The coarse 3/4-10 UNC thread allows for faster assembly and better performance in applications where slight surface contamination or minor thread damage is a concern. It is installed by machinists, millwrights, and industrial maintenance technicians.

Key Features

• 3/4-10 UNC coarse-thread form for robust clamping and vibration resistance
• 15-inch length under head for deep-reach and thick-stack fastening applications
• 5/8-inch hex socket drive for use with standard hex keys and torque wrenches
• Alloy steel construction provides high tensile strength
• Black oxide finish offers mild corrosion resistance and reduces light reflection
• Partially threaded shank distributes shear load along unthreaded body
• Meets ASME/ANSI B18.3 and ASTM A574 fastener standards

Compatibility

Designed as an OEM-style replacement or standard-production hex socket cap screw for industrial and mechanical assemblies requiring a 3/4-10 UNC partially threaded fastener with a 15-inch length under head.

Installation Notes

Installation is performed by machinists, millwrights, or industrial maintenance technicians using a calibrated torque wrench with the appropriate 5/8-inch hex bit. De-energize and lock out all equipment before fastener installation or removal in accordance with applicable OSHA lockout/tagout procedures. Inspect the mating threaded hole for damage or contamination before driving the screw. Do not exceed the rated torque for the fastener grade, and apply thread lubricant only when specified by the assembly drawing.
