Value Collection -33710-6 Hex Socket Cap Screw 7/8-9 Unc

Product Description

The VALUE COLLECTION -33710-6 is a partially threaded hex socket cap screw designed for high-strength fastening applications in mechanical assemblies, tooling fixtures, and industrial equipment. It features a 7/8-9 UNC thread size, a 6-inch length under head, and a 3/4-inch hex drive for use with a standard hex key or Allen wrench. The screw is machined from alloy steel and finished with a black oxide coating that provides mild corrosion resistance and reduces surface glare. This fastener meets ASME/ANSI B18.3 and ASTM A574 standards, making it appropriate for structural and high-torque fastening work.

This screw is suited for industrial maintenance, machine building, and fabrication environments where a socket-drive cap screw with a coarse UNC thread is required. Partial threading provides improved clamping force in through-hole and counterbored applications. Licensed machinists, millwrights, and maintenance mechanics commonly specify this fastener type for securing machine components, jigs, dies, and structural fixtures in both shop and field settings.

Key Features

• 7/8-9 UNC coarse thread for strong thread engagement in steel and alloy substrates
• 6-inch length under head accommodates deep counterbores and stacked assemblies
• 3/4-inch hex socket drive for high-torque installation with standard hex keys
• Partially threaded shank provides improved clamping performance in through-hole applications
• Alloy steel construction meets ASTM A574 high-strength socket screw requirements
• Black oxide finish offers mild corrosion resistance and a low-glare surface

Compatibility

Designed as an OEM-style and aftermarket replacement hex socket cap screw for industrial machinery, tooling fixtures, and mechanical assemblies requiring a 7/8-9 UNC coarse thread fastener.

Installation Notes

Installation is performed by machinists, millwrights, or qualified maintenance personnel using a calibrated torque wrench and a properly sized 3/4-inch hex key. De-energize and lock out all equipment per OSHA LOTO procedures before fastener installation or removal. Verify thread condition in the mating part before installation and apply thread lubricant or thread-locking compound as appropriate for the application. Do not exceed the rated torque for the fastener grade.
