Value Collection 587663PR Pan Head Phillips Machine Screw

Product Description

The VALUE COLLECTION 587663PR is a 1/4-20 pan head Phillips machine screw designed for general fastening applications in metal, wood, and composite assemblies. Measuring 2 inches in length under head with a Unified National Coarse (UNC) thread form, this screw is manufactured from Grade 2 steel with a zinc finish that provides basic corrosion resistance. The pan head profile offers a low-profile bearing surface suited for through-hole and clearance-hole installations. These screws are sold in a minimum order quantity of 100 pieces per package, making them appropriate for production, maintenance, and service work where volume fastening is required.

This screw is used across residential and commercial construction, HVAC equipment assembly, electrical enclosure work, and general mechanical maintenance. The 1/4-20 UNC thread is one of the most common inch-series thread sizes and fits standard tapped holes found in equipment frames, brackets, junction boxes, and sheet metal assemblies. The Phillips drive is compatible with standard No. 2 Phillips bits and screwdrivers. The zinc finish suits indoor and light-exposure environments where moderate protection against oxidation is adequate.

Key Features

• 1/4-20 UNC thread for broad compatibility with standard tapped hardware
• 2-inch length under head for medium-depth fastening applications
• Pan head profile provides a flat bearing surface without countersinking
• Phillips drive accepts standard No. 2 Phillips bits
• Grade 2 steel construction balances strength and cost for general-purpose use
• Zinc finish offers basic corrosion resistance for indoor and light-duty environments

Compatibility

Designed as a general-purpose inch-series machine screw suitable for standard 1/4-20 tapped holes in metal frames, enclosures, brackets, and equipment assemblies across HVAC, electrical, and mechanical trade applications.

Installation Notes

Installation is performed by hand or with a No. 2 Phillips bit and driver. Ensure the mating hole is properly tapped to 1/4-20 UNC before driving to avoid thread damage. De-energize any electrical equipment and shut off relevant systems before accessing fastener locations inside live panels or mechanical assemblies. Do not overtighten into thin sheet metal or soft materials, as Grade 2 steel screws can strip tapped threads if torque is not controlled.
