Value Collection -33710-3 Hex Socket Cap Screw 7/8-9 Unc

Product Description

The VALUE COLLECTION -33710-3 is a hex socket cap screw designed for high-strength fastening applications in mechanical assemblies, fixtures, and structural components. Threaded 7/8-9 UNC and measuring 8 inches in length under the head, this fastener is partially threaded and driven with a 3/4-inch hex key. Manufactured from alloy steel with a black oxide coating, it delivers the tensile strength and corrosion resistance required for demanding industrial and maintenance environments. It meets ASME/ANSI B18.3 and ASTM A574 standards, making it appropriate for load-bearing and precision-fit applications.

This screw is suited for use in general industrial machinery, tooling, and fabrication work where a recessed hex drive and high-grade alloy steel construction are specified. Partially threaded shanks provide clamping strength and are commonly used where the unthreaded shank portion needs to pass through a clearance hole or align mating parts. Machinists, millwrights, and maintenance technicians working in manufacturing, metalworking, and heavy equipment settings are the typical end users.

Key Features

• 7/8-9 UNC thread size for reliable engagement in standard tapped holes
• 8-inch length under head accommodates deep-stack or long-reach fastening applications
• Partially threaded shank provides clamping force and clearance-hole alignment
• 3/4-inch hex socket drive for high-torque installation with standard hex keys or Allen drive tooling
• Alloy steel construction meets ASTM A574 for high-strength fastener requirements
• Black oxide coating provides mild corrosion resistance and reduces light reflection

Compatibility

Designed as an OEM-style and aftermarket replacement hex socket cap screw for applications requiring a 7/8-9 UNC partially threaded fastener conforming to ASME/ANSI B18.3 and ASTM A574 standards.

Installation Notes

Installation should be performed by a qualified mechanic, machinist, or maintenance technician using a properly sized 3/4-inch hex key or Allen drive tool. Ensure the mating tapped hole is clean, undamaged, and matches the 7/8-9 UNC thread specification before installation. Apply thread lubricant or thread-locking compound as required by the application engineer or equipment OEM. Never use an improperly sized driver, as this can damage the socket and prevent proper torque application.
