Value Collection 011047P Hex Socket Cap Screw 5-40 Unc

Product Description

The VALUE COLLECTION 011047P is a hex socket cap screw designed for secure mechanical fastening in tight-clearance applications where a hex key is required. Threaded 5-40 UNC and fully threaded along its 1/2-inch length under the head, this fastener delivers consistent clamping force across the full grip range. It is manufactured from alloy steel and finished with a black oxide coating that provides mild corrosion resistance and reduces light reflection in service environments. The 3/32-inch hex drive size suits standard hex keys and Allen wrenches common in industrial and mechanical assembly work. This screw is appropriate for use by machinists, maintenance technicians, and assembly professionals working with precision mechanical components.

This fastener is suited for light-duty mechanical assemblies, instrument enclosures, fixtures, jigs, and similar applications where a low-profile socket head is preferred over an external-drive fastener. The 5-40 UNC thread series is commonly found in small machine components, precision instruments, and electronic enclosures requiring controlled thread engagement. Its fully threaded body maximizes thread contact in thin or shallow tapped holes, making it practical for assemblies with limited material depth.

Key Features

• 5-40 UNC thread form for compatibility with standard 5-40 tapped holes
• Fully threaded body along the entire 1/2-inch length under the head
• 3/32-inch internal hex drive for use with standard hex keys
• Alloy steel construction for strength in small-diameter fastener applications
• Black oxide finish provides mild corrosion resistance and a low-reflectance surface
• Meets ASME/ANSI B18.3 and ASTM A574 standards

Compatibility

Designed as a standard replacement or stock fastener for any assembly using 5-40 UNC tapped holes requiring a hex socket cap screw per ASME/ANSI B18.3.

Installation Notes

Installation is performed using a 3/32-inch hex key or Allen wrench; ensure the driver is fully seated in the socket before applying torque to avoid rounding the drive recess. Verify the tapped hole thread class matches the 5-40 UNC specification before installation. De-energize and lock out any equipment before servicing fasteners on powered assemblies. Do not exceed the rated drive engagement depth in shallow tapped holes.
