Value Collection R63032882 4-40 X 0.5 in Oval Head Phillips Screw

Product Description

The VALUE COLLECTION R63032882 is a 4-40 UNC machine screw designed for precision fastening applications in light mechanical assemblies. Featuring an oval head profile and Phillips drive, this screw seats flush with a countersunk surface while providing a low-profile, finished appearance. Manufactured from 18-8 stainless steel with a bright, uncoated finish, it resists corrosion in moderate-exposure environments. The screw measures 0.5 inches in overall length with a 0.5-inch length under the head, making it well suited for thin-panel and chassis work. Sold in a minimum order quantity of 100 pieces per package, this fastener is appropriate for electronics assembly, HVAC control panels, enclosures, and general sheet-metal work.

This machine screw is used wherever a 4-40 UNC threaded hole requires a corrosion-resistant, reusable fastener with a countersunk oval seating surface. Common applications include control board housings, electrical enclosures, instrument panels, and light-duty mechanical assemblies found in residential and commercial HVAC equipment, plumbing fixtures, and electrical device covers. The Phillips drive allows for installation with standard hand tools or power drivers in production and field-service environments.

Compatibility

Designed as a standard 4-40 UNC machine screw replacement suitable for any application requiring an oval-head Phillips fastener in that thread size and 0.5-inch length.

Installation Notes

Installation is performed using a Phillips screwdriver or bit driver sized for a number 4 screw head. Verify that the mating threaded hole is properly tapped to 4-40 UNC specification before driving to avoid cross-threading. For stainless-to-stainless assemblies, apply an appropriate anti-seize compound to prevent galling. Do not overtighten, as stainless steel fasteners are susceptible to thread damage under excess torque.
