Value Collection 307166BR Hex Socket Cap Screw 3/4-10 Unc

Product Description

The VALUE COLLECTION 307166BR is a hex socket cap screw designed for high-strength fastening applications in mechanical assemblies, structural connections, and industrial equipment. It features a 3/4-10 UNC thread size with 1.5 inches of length under the head and is fully threaded from end to thread run-out. The 9/16-inch hex drive accepts a standard Allen-type socket driver or hex key. Manufactured from alloy steel with a black oxide finish, this screw meets ASTM A574 requirements for mechanical properties, making it suitable where tensile strength and torque resistance matter.

This screw is commonly used in machine frames, jigs, fixtures, motor mounts, and general industrial fabrication where a flush or low-profile head is required. The fully threaded body provides consistent clamping force along the full engaged length. It is appropriate for use in both shop-fabricated assemblies and field maintenance work where coarse UNC threading is preferred for faster engagement in steel or tapped aluminum components.

Key Features

• 3/4-10 UNC coarse thread for fast engagement and strong pull-out resistance
• 1.5 inches length under head, fully threaded
• 9/16-inch hex socket drive for use with standard Allen keys or socket drivers
• Alloy steel construction meets ASTM A574 mechanical requirements
• Black oxide finish provides mild corrosion resistance and reduces light reflection

Compatibility

Designed as a standard 3/4-10 UNC hex socket cap screw for use in any tapped hole or threaded insert conforming to UNC coarse thread specifications at 3/4-inch nominal diameter.

Installation Notes

Installation is performed with a 9/16-inch hex key or socket driver. Ensure the mating tapped hole is clean and free of debris before threading. Apply appropriate thread lubricant or thread-locking compound per the assembly specification. Follow applicable torque requirements per ASTM A574 or the equipment manufacturer's fastener specification.
