Value Collection R50000189 Pan Head Phillips Machine Screw

Product Description

The VALUE COLLECTION R50000189 is a 1/4-20 x 2.5-inch pan head machine screw designed for general-purpose mechanical fastening applications. Manufactured from Grade 2 steel with a zinc-plated finish, this screw provides corrosion resistance suitable for indoor and light-duty outdoor assemblies. The pan head profile offers a low-profile, wide bearing surface, and the Phillips drive allows for fast installation with standard power or hand tools. Length is measured from under the head, confirming 2.5 inches of thread engagement. This screw follows Unified National Coarse (UNC) thread standards and is sold in quantities of 1 package with a minimum order of 100 pieces.

This fastener is used in light structural assembly, equipment enclosures, HVAC components, electrical panels, and general sheet metal or machined-part applications where a 1/4-20 UNC thread is specified. The zinc plating makes it a practical choice for applications requiring basic corrosion resistance without the cost of stainless steel. It is suitable for use in residential and commercial equipment assembly, maintenance, and repair work performed by HVAC technicians, electricians, plumbers, and general maintenance professionals.

Key Features

Compatibility

Designed as a standard 1/4-20 UNC pan head machine screw suitable for any application requiring this thread size and head style in inch-measurement fastener systems.

Installation Notes

Install using a Phillips screwdriver or a compatible Phillips bit with a power driver. Ensure the mating hole is tapped to 1/4-20 UNC or use an appropriate nut and washer as required by the application. De-energize any electrical equipment before fastening work inside panels or enclosures. Do not overtighten Grade 2 fasteners in soft materials such as aluminum or plastic, as thread stripping can occur.
