Value Collection 0414MPR 4-40 X 7/8 in Round Head Phillips Screw

Product Description

The VALUE COLLECTION 0414MPR is a 4-40 x 7/8 inch round head Phillips machine screw manufactured from steel with a zinc-plated finish. Designed to the ASME B18.6.3 and SAE J82 standards, this fastener delivers consistent thread engagement and corrosion resistance for light-duty mechanical assemblies. The round head profile provides a low-profile seating surface suitable for panels, enclosures, and equipment chassis. Thread size is 4-40 UNC, with length measured under the head at 7/8 inch. This screw is sold in a minimum order quantity of 100 pieces, making it suited for production and maintenance applications where fastener volume is required.

This fastener is commonly used in electrical enclosures, control panels, HVAC equipment cabinets, light-gauge sheet metal assemblies, and general mechanical equipment where 4-40 threaded hardware is specified. The Phillips drive is compatible with standard power drivers and hand screwdrivers, supporting efficient installation in production and field service environments. The zinc plating provides basic corrosion protection suitable for indoor and sheltered applications.

Installation Notes

Installation is performed by electricians, HVAC technicians, and mechanical assemblers using a Phillips screwdriver or power driver with appropriate bit size. Always power down and de-energize any electrical equipment before accessing panels or enclosures. Avoid overtightening in light-gauge sheet metal to prevent thread stripping. Verify thread engagement depth is adequate for the mating material before finalizing the assembly.
