Value Collection 580531PR 12-24x1 Flat Head Slotted Machine Screw

Product Description

The VALUE COLLECTION 580531PR is a 12-24 x 1 inch overall length flat head slotted machine screw manufactured from Grade 2 steel with a zinc finish. It features a Unified National Coarse (UNC) thread form and is sold without a washer. The flat head profile sits flush with or below the mating surface when installed in a countersunk hole, making it a standard choice for general fastening in sheet metal, electrical enclosures, and light mechanical assemblies. This screw ships in multiples of 100 units, suited for production or maintenance shop stock.

This fastener is used in residential and light commercial applications where a low-profile flush-mount screw is required. Typical installations include electrical panels, junction boxes, equipment covers, and general mechanical assemblies. The zinc coating provides basic corrosion resistance suitable for dry indoor environments. Maintenance technicians, electricians, and general assembly workers are the primary installers of this fastener type.

Installation Notes

Installation requires a flat-blade screwdriver sized to the slotted head. For flush mounting, the mating material must be countersunk to the correct angle to seat the flat head properly. De-energize any electrical equipment before fastening screws in or near energized enclosures in accordance with applicable NEC requirements. Do not overtighten, as Grade 2 steel has lower tensile strength than higher-grade fasteners.
