Value Collection 581297PR Hex Socket Cap Screw 10-24 Unc

Product Description

The VALUE COLLECTION 581297PR is a hex socket cap screw designed for secure fastening in mechanical assemblies where a recessed drive is required. Sized at 10-24 UNC thread with a 3-inch length under head, this fastener is partially threaded and driven with a 5/32-inch hex key. Constructed from alloy steel with a black oxide coating, it delivers solid corrosion resistance and surface hardness suited for high-stress fastening applications. This screw meets ASME/ANSI B18.3 and ASTM A574 standards, making it appropriate for precision and structural fastening work across industrial, mechanical, and maintenance environments.

This fastener is suited for use in machinery, fixtures, tooling, and general mechanical assemblies requiring a low-profile socket head with controlled thread engagement. The partial threading allows the unthreaded shank to act as a shoulder in clearance holes, which is useful in alignment-critical installations. Machinists, millwrights, maintenance technicians, and fabricators commonly install this type of fastener in both production and field repair settings.

Key Features

• 10-24 UNC thread for compatibility with standard unified coarse thread tapped holes
• 3-inch length under head with partial threading for shoulder-fit applications
• 5/32-inch hex drive for use with standard hex keys and Allen wrenches
• Alloy steel construction meets ASTM A574 for high-strength fastener performance
• Black oxide finish provides moderate corrosion resistance and reduces light reflection
• Conforms to ASME/ANSI B18.3 dimensional standards

Compatibility

Designed as a standard replacement or stock fastener for any application requiring a 10-24 UNC hex socket cap screw with a 3-inch length under head and 5/32-inch drive, conforming to ASME/ANSI B18.3 and ASTM A574 specifications.

Installation Notes

Install using a calibrated 5/32-inch hex key or Allen driver; avoid using worn or undersized keys to prevent drive rounding. Ensure the tapped hole meets 10-24 UNC thread specification before installation. Apply appropriate thread lubricant or locking compound as required by the assembly specification. Power down and de-energize any equipment before replacing fasteners in live mechanical assemblies.
