Value Collection 015043PR Hex Socket Cap Screw 5-40 Unc

Product Description

The VALUE COLLECTION 015043PR is a hex socket cap screw designed for precision fastening applications requiring a compact, high-strength connection. Manufactured from alloy steel with a black oxide finish, this screw meets ASME/ANSI B18.3, ASTM A574, and IFI 124 standards. It features a 5-40 UNC thread size, a 1/4 inch length under head, and is driven with a 3/32 inch hex socket key. The black oxide coating provides mild corrosion resistance and reduces light reflection, making it suitable for both mechanical assemblies and maintenance applications. The fully threaded shank ensures maximum thread engagement across the full length under head.

This socket cap screw is suited for light mechanical assemblies, instrument panels, and equipment enclosures where a low-profile, recessed fastener is required. The 5-40 UNC thread is common in small-bore tapped holes found in precision components, electronics housings, and light-duty structural brackets. Installation is performed by tradespeople, machinists, and maintenance technicians working on equipment that requires a clean, flush fastening surface. The compact drive size is well-suited for confined spaces where standard fastener heads would not fit.

Key Features

• 5-40 UNC thread size for use in standard small-bore tapped holes
• 1/4 inch length under head with full threading along the entire shank
• 3/32 inch hex socket drive for use with standard hex keys or Allen drivers
• Alloy steel construction provides strength beyond standard mild steel fasteners
• Black oxide finish offers mild corrosion resistance and a non-reflective surface
• Meets ASME/ANSI B18.3, ASTM A574, and IFI 124 fastener standards

Compatibility

Designed as a standard-dimension hex socket cap screw for use in any application with a 5-40 UNC tapped hole requiring a 1/4 inch length under head fastener.

Installation Notes

Installation requires a 3/32 inch hex key or Allen driver. Always ensure the mating tapped hole is clean and free of debris before threading to avoid cross-threading or galling. Power down and de-energize any equipment before replacing fasteners on electrical enclosures or panels. Torque to the value specified by the equipment manufacturer or applicable assembly drawing.
