The VALUE COLLECTION R50000286 is a 1/4-20 flat head Phillips machine screw designed for general-purpose fastening in mechanical assemblies, equipment panels, and structural components. Manufactured from Grade 2 steel with a zinc finish for basic corrosion resistance, this screw measures 5/8 inches in overall length. The flat head profile sits flush with or below the mating surface when installed in a countersunk hole, making it well suited for applications where a smooth finished surface is required. Sold in a minimum order quantity of 100 pieces, this fastener is a standard choice for production, maintenance, and repair work across multiple trades.
This screw is appropriate for use in light-duty mechanical and structural assemblies where an inch-series UNC thread is specified. Typical applications include panel fastening, equipment housing assembly, brackets, and general maintenance tasks in HVAC, electrical, and plumbing equipment. The Phillips drive allows use with standard power drivers and manual screwdrivers. The 1/4-20 UNC thread form is one of the most common inch-series coarse thread standards encountered in trade work, ensuring broad tooling and hardware compatibility.
Designed as a standard inch-series UNC machine screw for general mechanical fastening applications where a 1/4-20 flat head Phillips fastener is specified.
Installation requires a properly sized countersunk or flat-bottom clearance hole in the mating material to seat the flat head flush. Use a Phillips screwdriver or driver bit matched to the screw size to avoid cam-out and head damage. Power down or de-energize any electrical or mechanical equipment before performing fastener service. Follow applicable equipment manufacturer torque guidance and relevant codes for the specific assembly being serviced.
