Value Collection 583687PR 1/4-20 X 4 in Round Head Slotted Screw

Product Description

The VALUE COLLECTION 583687PR is a 1/4-20 unified coarse thread (UNC) machine screw with a round head and slotted drive, designed for general mechanical fastening applications. Manufactured from alloy steel with a zinc finish for basic corrosion resistance, this screw measures 4 inches in length under the head. It is suited for use in assemblies where a traditional slotted round head profile is required and where dimensional consistency is critical. Electricians, HVAC technicians, plumbers, and general maintenance professionals regularly use this fastener size in equipment enclosures, brackets, and mechanical assemblies.

This screw is appropriate for residential and light commercial applications involving metal-to-metal or metal-to-component fastening. The 1/4-20 thread size is one of the most common inch-series coarse thread fasteners in trade use, making it a practical stock item for service vehicles, shop bins, and parts rooms. The zinc coating provides a baseline level of protection against oxidation in dry or mildly humid indoor environments. Sold individually as a single piece with a minimum order quantity of 100 units.
