Value Collection R52001080 1/4-20x4 Flat Head Phillips Screw

Product Description

The VALUE COLLECTION R52001080 is a 1/4-20 x 4-inch flat head Phillips machine screw manufactured from steel with a zinc finish. It carries a Grade J82 designation per ASME B18.6.3 and SAE J82, making it a standard-grade fastener suited for general mechanical assembly. The flat head profile sits flush with or below the mating surface when driven into a countersunk hole, which keeps assembled surfaces clean and snag-free. Phillips drive allows installation with common hand or power tools. This screw is sold individually but requires a minimum order quantity of 50 units per order.

This fastener is appropriate for light to medium-duty mechanical assemblies in industrial, commercial, and trade environments. Typical applications include panel mounting, equipment enclosures, brackets, and general machine assembly where a flush fastener profile is required. The zinc finish provides a basic level of corrosion resistance suitable for indoor and dry-environment use. HVAC techs, electricians, plumbers, and general maintenance trades routinely use this screw size for panel work and equipment enclosure assembly.

Installation Notes

Install using a Phillips screwdriver or power driver with the appropriate bit size to avoid cam-out and head damage. When countersinking, match the countersink angle to the screw head angle for full flush seating. De-energize and lock out any electrical equipment before installing or removing fasteners on or near live panels, per NFPA 70E guidelines. Do not overtighten steel screws into softer base materials such as aluminum without accounting for thread strip-out limits.
