Value Collection 015047PR Hex Socket Cap Screw 5-40 Unc

Product Description

The VALUE COLLECTION 015047PR is a hex socket cap screw designed for precision fastening in mechanical assemblies, machine components, and industrial fixtures. It features a 5-40 UNC thread with a 1/2-inch length under head and is driven by a 3/32-inch hex key. The fastener is manufactured from alloy steel and finished with a black oxide coating that provides mild corrosion resistance and reduces light reflection. Fully threaded along its entire length, it delivers consistent clamping force and thread engagement. Licensed electricians, machinists, and mechanical technicians working on control panels, equipment enclosures, and precision assemblies routinely specify this screw size.

This cap screw is suited for light-duty mechanical and structural fastening applications where a compact, low-profile socket head is required. The 5-40 UNC thread is common in instrumentation, small appliance housings, electronics enclosures, and precision machine work. The black oxide finish makes it a practical choice in applications where surface appearance and moderate rust inhibition matter. It is sold individually but subject to a minimum order quantity of 100 pieces per transaction.

Key Features

• 5-40 UNC thread for compatibility with standard inch-series tapped holes in that size range
• 1/2-inch length under head suits shallow-clearance fastening applications
• 3/32-inch hex drive allows precise torque application with a standard hex key or Allen wrench
• Fully threaded shank maximizes thread engagement over the entire fastener length
• Alloy steel construction delivers higher tensile strength compared to low-carbon steel fasteners
• Black oxide coating provides mild corrosion resistance and a uniform dark finish

Compatibility

Designed as a standard inch-series hex socket cap screw suitable for use in any application requiring a 5-40 UNC threaded fastener with a 1/2-inch length under head.

Installation Notes

Installation requires a 3/32-inch hex key or Allen wrench; use a T-handle or torque-limiting driver for controlled seating in tapped blind holes. Confirm the mating tapped hole meets 5-40 UNC thread form and depth requirements before driving. Follow applicable ASME or equipment manufacturer torque guidelines for the fastener grade. Avoid overtightening in thin or soft substrates, as the fine thread engagement can strip with excessive force.
