Value Collection R52001142 Flat Head Phillips Machine Screw

Product Description

The VALUE COLLECTION R52001142 is a 5/16-18 flat head Phillips machine screw designed for general mechanical fastening applications. It features an overall length of 2.5 inches and is manufactured from steel with a zinc-plated finish for basic corrosion resistance. The flat head profile sits flush with or below the mating surface when installed in a countersunk hole, making it suited for assemblies where a low-profile fastener is required. This screw conforms to ASME B18.6.3 and SAE J82 standards and is rated Material Grade J82. It is supplied individually per package with a minimum order quantity of 10 units.

This fastener is appropriate for light-duty to medium-duty mechanical assemblies across trade and industrial applications. Common uses include panel mounting, equipment housings, electrical enclosures, and general equipment fabrication where a flush-mount Phillips-drive screw is specified. The 5/16-18 unified coarse thread is a widely used size in steel-on-steel assemblies. No washer is included or required by the fastener design, per the without-washer specification.

Compatibility

Designed as a standard 5/16-18 x 2.5 inch flat head Phillips machine screw suitable for use in any application specifying ASME B18.6.3 or SAE J82 compliant inch-series fasteners.

Installation Notes

Installation requires a properly sized countersunk hole to allow the flat head to seat flush with the mating surface. Use a Phillips screwdriver or bit sized for the fastener drive recess to avoid cam-out and head damage. De-energize and lock out any equipment before fastening components on or near electrical assemblies, per NFPA 70E guidelines. Do not reuse fasteners that show signs of thread damage, corrosion, or deformation.
