Value Collection MPFI0-500370-100BX 5-40 Machine Screw

Product Description

The VALUE COLLECTION MPFI0-500370-100BX is a 5-40 UNC machine screw designed for light-duty mechanical fastening applications. It features a flat head profile with a Phillips drive and measures 3/8 inches in overall length. Constructed from Grade 2 steel with a zinc-plated finish, this screw provides basic corrosion resistance suitable for indoor and general-purpose assemblies. It ships in a minimum order quantity of 100 pieces, making it appropriate for production, maintenance, and repair operations where consistent fastener supply is needed.

This screw is suited for electrical enclosures, control panels, HVAC equipment housings, and light mechanical assemblies where a flush-seating flat head is required. The Phillips drive is compatible with standard power and hand drivers. The zinc plating offers surface protection in dry or mildly humid environments. The 5-40 thread is commonly found in instrument-grade and light-duty metal applications.

Installation Notes

Install using a No. 1 Phillips screwdriver or a matching power driver bit to avoid cam-out and head damage. Always thread into a properly tapped or pre-threaded hole sized for 5-40 UNC; do not force-thread into undersized holes. Follow applicable equipment manufacturer torque recommendations when fastening into thin metal or plastic substrates. Inspect the zinc finish before use and discard any screws showing corrosion or thread deformation.
