Value Collection 307224BR Hex Socket Cap Screw 7/8-9 Unc

Product Description

The VALUE COLLECTION 307224BR is a hex socket cap screw designed for high-strength fastening applications across industrial, mechanical, and structural assemblies. Built from alloy steel with a black oxide coating, this fastener delivers corrosion resistance and a consistent bearing surface under torque. It measures 8 inches in length under the head and uses a 9/16-inch hex drive, making it compatible with standard hex keys and socket drive tools. The partially threaded shank provides a grip section that resists lateral movement in bolted joints. This screw meets ASTM A574 standards, confirming its suitability for demanding load-bearing applications.

This screw is used in general industrial maintenance, machine assembly, die and mold work, and heavy equipment repair. The 7/8-9 UNC thread form is a coarse-thread specification widely used in North American industrial equipment. The black oxide finish is appropriate for indoor or protected environments where light corrosion resistance is required. Maintenance technicians, millwrights, and mechanical contractors will find this size and drive configuration applicable across a range of bolted connections in ferrous assemblies.

Key Features

• 7/8-9 UNC coarse-thread form for broad compatibility with standard tapped holes
• 8-inch length under head suits deep-reach clamping and structural fastening needs
• 9/16-inch hex socket drive for use with standard hex keys or socket wrenches
• Partially threaded shank provides a grip length for shear-load resistance
• Alloy steel construction meets ASTM A574 high-strength fastener standard
• Black oxide coating provides light corrosion resistance and reduces light reflection

Compatibility

Designed as an OEM-style replacement or standard-fit fastener for applications requiring a 7/8-9 UNC hex socket cap screw meeting ASTM A574 specifications.

Installation Notes

Installation should be performed by qualified mechanical or maintenance personnel familiar with high-strength fastener torque procedures. Always verify the tapped hole thread specification matches 7/8-9 UNC before installation. Use a properly sized 9/16-inch hex key or socket drive tool to seat the fastener and apply appropriate torque per the equipment manufacturer's specifications. Inspect the mating threads for damage or contamination before assembly.
