Value Collection 0505MPR 5-40 Round Head Phillips Machine Screw

Product Description

The VALUE COLLECTION 0505MPR is a round head Phillips drive machine screw designed for precise mechanical fastening in a wide range of industrial and commercial applications. Sized at 5-40 thread with a 5/16-inch length under head, this screw is manufactured from steel with a zinc finish for basic corrosion resistance. It conforms to ASME B18.6.3 and SAE J82 standards, ensuring dimensional accuracy and consistent torque performance. Material grade is J82. The zinc coating provides a serviceable surface protection layer suitable for dry and low-moisture environments. These screws are sold in a minimum order quantity of 100 per package.

This machine screw is suited for light mechanical assemblies, electrical enclosures, panel mounting, and general-purpose fastening tasks where a standard inch-series 5-40 thread is specified. The round head profile provides a low-profile, smooth dome finish above the mating surface, which is preferred when clearance or aesthetics are a concern. The Phillips drive is compatible with standard Phillips screwdrivers and power driver bits. Typical users include maintenance technicians, electricians, mechanical assemblers, and production line personnel working with sheet metal, light structural components, or electrical hardware.

Compatibility

Designed as a standard inch-series machine screw compatible with any application specifying a 5-40 UNC thread, round head, Phillips drive fastener per ASME B18.6.3.

Installation Notes

Installation is performed with a No. 1 Phillips screwdriver or appropriately sized power driver bit. Always ensure the mating thread or nut is clean and free of debris before driving. Do not overtighten, as small-diameter machine screws are susceptible to thread stripping. When used in electrical enclosures or panels, follow applicable NEC guidelines for fastener use and panel integrity.
