The VALUE COLLECTION 580887PS is a 3/8-16 x 4-inch flat head slotted machine screw manufactured from Grade 2 steel with a zinc finish. Designed for general-purpose fastening applications, this screw features a flat countersunk head profile that sits flush with or below the mating surface when installed. The unified national coarse (UNC) thread form provides reliable clamping force across a wide range of materials. At 0.14 pounds per unit, it is suited for structural and mechanical assemblies where a low-profile fastener is required. Licensed trade professionals and skilled fabricators typically use this hardware in equipment panels, brackets, and general metalwork.
This machine screw is used in light to medium-duty mechanical and structural assemblies across industrial, commercial, and residential maintenance applications. The flat head profile makes it well suited for countersunk through-holes in metal panels, wood, and plastic components. The zinc finish provides basic corrosion resistance for indoor and sheltered outdoor environments. It is commonly installed by millwrights, maintenance technicians, electricians, and general contractors working with standard inch-dimensioned hardware. The overall length is measured from tip to top of head, with 4 inches of full grip length under the head.
Designed as a standard-dimension replacement or stock fastener for any application requiring a 3/8-16 UNC flat head slotted machine screw with a 4-inch overall length in inch-measurement systems.
Install using a properly sized flat-blade screwdriver or slotted bit to avoid cam-out and head damage. Ensure the receiving hole is correctly countersunk to the flat head angle before driving to achieve a flush seating surface. De-energize and lock out any equipment before installing or replacing fasteners on live assemblies per applicable OSHA lockout/tagout procedures. Do not exceed the torque capacity of Grade 2 hardware; consult a fastener load table for the specific joint application.
