Value Collection 586021PR 2-56 X 3/4 Flat Head Phillips Screw

Product Description

The VALUE COLLECTION 586021PR is a 2-56 machine screw with a flat head and Phillips drive, manufactured from steel with a zinc finish. The flat head profile sits flush with the mating surface when installed, making it a common choice in assemblies where a low-profile fastener is required. The zinc coating provides basic corrosion resistance in general indoor applications. This screw meets ASME B18.6.3 and SAE J82 dimensional and material standards. Machinists, technicians, and maintenance professionals use this fastener in light-duty mechanical assemblies, electronics enclosures, and instrument panels where a 2-56 thread form is specified.

The 586021PR is suited for applications calling for a 2-56 unified coarse thread in a 3/4 inch overall length. It is commonly installed in precision sheet metal assemblies, control panels, HVAC equipment covers, and small appliance housings. The flat countersunk head requires a matching countersunk hole in the mating material for a flush-mount installation. This fastener is sold in a minimum order quantity of 100 pieces per package, making it practical for shop stock or production-line use.

Installation Notes

Installation requires a properly countersunk clearance hole sized for the 2-56 thread and flat head profile. Use a Phillips screwdriver or bit matched to the drive size to avoid cam-out and head damage. Do not overtighten — the 2-56 thread form is fine and susceptible to stripping in soft or thin base materials. Always confirm thread engagement depth and material compatibility before installation.
