Value Collection 307222BR Hex Socket Cap Screw 7/8-9 Unc

Product Description

The VALUE COLLECTION 307222BR is a hex socket cap screw designed for high-strength bolted connections in industrial and mechanical assemblies. It features a 7/8-9 UNC thread and measures 7 inches in length under the head with partial threading. The 9/16-inch hex drive socket accepts a standard hex key or Allen driver. Finished in black oxide, the alloy steel construction resists corrosion and provides the tensile strength required for demanding fastening applications. This fastener meets ASTM A574 standards, making it appropriate for structural and precision mechanical use across manufacturing, maintenance, and heavy equipment repair.

This screw is suited for industrial, commercial, and heavy-duty mechanical applications where a high-strength, socket-drive fastener is required. The partially threaded shank provides a bearing surface useful in shear-loaded joints and precision assemblies. Typical installation environments include machine frames, tooling fixtures, hydraulic component mounting, and structural steel assemblies where controlled torque and positive seating are priorities.

Key Features

• 7/8-9 UNC thread for compatibility with standard unified coarse-thread tapped holes
• 7 inches of length under head with partial threading for shear-load and bearing-surface applications
• 9/16-inch hex socket drive for use with standard Allen keys or hex-socket drivers
• Alloy steel construction meets ASTM A574 high-strength fastener standard
• Black oxide finish provides mild corrosion resistance and reduces light reflection in exposed assemblies

Compatibility

Designed as an OEM-style replacement or stock fastener for industrial equipment, machine frames, and mechanical assemblies requiring a 7/8-9 UNC hex socket cap screw conforming to ASTM A574.

Installation Notes

Installation is typically performed by millwrights, maintenance mechanics, or general trade technicians using a calibrated torque wrench and the appropriate 9/16-inch hex key or socket driver. Always verify that the mating tapped hole meets the same thread standard and is free of debris before installation. Follow ASTM A574 torque guidelines and applicable equipment manufacturer specifications when tightening. Avoid reusing fasteners that show thread deformation or corrosion damage.
