Value Collection 583088PR Machine Screw 2-56 5/8 Round Head

Product Description

The VALUE COLLECTION 583088PR is a 2-56 unified coarse thread machine screw with a round head and slotted drive, manufactured from steel with a zinc finish. It measures 5/8 inch in length under the head and meets ASME B18.6.3 and SAE J82 standards for dimensional and mechanical conformance. This fastener is suited for light-duty mechanical assemblies where a low-profile round head and simple slotted installation are appropriate. Installers in electrical, HVAC, and general mechanical trades use this screw for panel mounting, light sheet metal work, and equipment assembly applications where small-diameter threaded fasteners are specified.

The 583088PR is used in residential and commercial applications requiring a No. 2 diameter, 56 threads-per-inch fastener. Common install scenarios include securing control board covers, junction box hardware, small access panels, and light-gauge brackets. The zinc finish provides basic corrosion resistance in dry indoor environments. This screw ships in a package quantity of one unit, with a minimum order quantity of 100 pieces, making it practical for stocking in trade shop inventory or field supply kits.

Key Features

• 2-56 unified coarse thread for reliable engagement in standard No. 2 tapped holes
• Round head profile keeps a low, clean appearance on finished panels and covers
• Slotted drive compatible with flat-blade screwdrivers and standard bit sets
• Zinc finish provides basic indoor corrosion resistance
• Conforms to ASME B18.6.3 and SAE J82 dimensional and grade standards
• 5/8 inch length under head suits typical light-gauge sheet metal and panel applications

Compatibility

Designed as a standard inch-system machine screw for use in any application specifying a No. 2-56 round head slotted fastener per ASME B18.6.3.

Installation Notes

Installation requires a flat-blade screwdriver or slotted bit sized for a No. 2 screw head. Always ensure the mating tapped hole or nut is properly threaded to 2-56 UNC specification before driving to avoid cross-threading. Power down and de-energize any electrical equipment before removing or reinstalling fasteners on control enclosures or panels. Do not overtighten in light-gauge sheet metal, as the fine thread form can strip thin material.
