Value Collection 581907PR Hex Socket Cap Screw 9/16-12 Unc

Product Description

The VALUE COLLECTION 581907PR is a hex socket cap screw designed for high-strength fastening applications in industrial, mechanical, and structural assemblies. It features a 9/16-12 UNC thread size, an 8-inch length under head, and a 7/16-inch hex drive. Constructed from alloy steel with a black oxide finish, this fastener delivers solid corrosion resistance and maintains clamping force under load. The fully threaded shaft maximizes thread engagement along the entire usable length. It is installed with a standard hex key or Allen wrench and is appropriate wherever ASME/ANSI B18.3 and ASTM A574 grade socket cap screws are specified.

This screw is suited for medium-to-heavy-duty fastening in manufacturing equipment, hydraulic assemblies, machine frames, and industrial fixtures requiring a recessed-drive cap screw. The 9/16-12 UNC coarse thread pattern is compatible with standard UNC tapped holes and is a common specification in industrial machinery maintenance and fabrication environments. The black oxide finish is appropriate for indoor and low-moisture applications where moderate surface protection is acceptable.

Key Features

• 9/16-12 UNC coarse thread for compatibility with standard UNC tapped holes
• 8-inch length under head for deep-reach fastening applications
• Fully threaded shaft maximizes thread engagement along the entire length
• 7/16-inch hex socket drive for use with standard hex keys or Allen wrenches
• Alloy steel construction meets ASTM A574 mechanical requirements
• Black oxide coating provides moderate corrosion and abrasion resistance

Compatibility

Designed as an OEM-style replacement or standard-stock fastener for applications specifying ASME/ANSI B18.3 hex socket cap screws in 9/16-12 UNC coarse thread.

Installation Notes

Installation is performed with a 7/16-inch hex key or Allen wrench. Verify the mating tapped hole is clean, properly sized, and free of debris before installation. Apply appropriate thread lubricant or thread-locking compound per the assembly specification. Follow applicable torque guidelines from the equipment manufacturer or relevant ASME standards when tightening.
