Value Collection 581169PR Hex Socket Cap Screw 5-40 Unc

Product Description

The VALUE COLLECTION 581169PR is a fully threaded hex socket cap screw designed for precision fastening in confined or recessed applications. Sized to a 5-40 UNC thread with a 3/32 inch hex drive and a 7/16 inch length under head, this fastener is machined from alloy steel and finished with a black oxide coating that provides baseline corrosion resistance and reduces surface glare. It meets ASME/ANSI B18.3 and ASTM A574 dimensional and strength standards. Machinists, maintenance technicians, and assembly professionals use socket cap screws where a low-profile, high-strength fastening point is required and where a hex key provides better torque access than a standard external hex head.

This screw is suited for light-duty mechanical assemblies, fixture construction, jig and tooling builds, and equipment maintenance tasks that call for a fine-thread 5-40 UNC fastener. The black oxide finish makes it a common choice in applications where a matte, non-reflective surface is preferred. Its compact drive size and fully threaded shank make it well adapted to thin-material and close-tolerance fastening scenarios encountered in manufacturing and field service environments.

Key Features

• 5-40 UNC thread for fine-thread engagement in precision assemblies
• 3/32 inch hex drive accepts standard hex keys and ball-end drivers
• 7/16 inch length under head for shallow-clearance fastening
• Fully threaded shank maximizes thread engagement across the full fastener length
• Alloy steel construction provides high tensile strength relative to fastener size
• Black oxide finish offers mild corrosion resistance and a low-glare surface
• Compliant with ASME/ANSI B18.3 and ASTM A574 standards

Compatibility

Designed as a standard replacement or stock fastener for any application requiring a 5-40 UNC fully threaded hex socket cap screw with a 3/32 inch drive and 7/16 inch length under head per ASME/ANSI B18.3.

Installation Notes

Installation requires a 3/32 inch hex key or ball-end driver; confirm the drive tool is fully seated before applying torque to avoid cam-out and rounding. Power down or de-energize any equipment before removing or replacing fasteners in live assemblies. Inspect mating threads for contamination or damage prior to installation and use thread-locking compound where vibration is a concern. Minimum order quantity for this SKU is 100 pieces.
