Value Collection MPPI0-401500-100BX 4-40 Pan Head Phillips Screw

Product Description

The VALUE COLLECTION MPPI0-401500-100BX is a 4-40 x 1.5 inches pan head machine screw with a Phillips drive, manufactured from Grade 2 steel with a zinc-plated finish. The pan head profile provides a wide, low-profile bearing surface suited to sheet metal, electronic enclosures, and light mechanical assemblies. The zinc plating offers basic corrosion resistance in dry indoor environments. Thread pitch follows the Unified National Coarse (UNC) standard at 4-40, making this screw compatible with standard 4-40 tapped holes and nuts. Length measurement is taken under the head. This box contains 100 screws and is sized for use by electricians, HVAC technicians, and equipment assemblers working on panel enclosures, junction boxes, and control board mounting applications.

These 4-40 machine screws are commonly used in light-duty fastening applications across residential and commercial trades. Typical uses include securing control boards, terminal strips, enclosure covers, and small mechanical components in electrical panels and HVAC equipment. The Phillips drive is compatible with standard No. 1 Phillips screwdrivers and power bits. The UNC thread form allows use with pre-tapped holes or standard hex nuts and nylon-insert lock nuts in 4-40 sizing. This package quantity of 100 pieces is suited for shop stock or job-lot use.

Compatibility

Designed as a standard 4-40 UNC machine screw suitable for any application requiring a pan head Phillips fastener in that thread size and 1.5-inch under-head length.

Installation Notes

Install with a No. 1 Phillips screwdriver or matching power bit to avoid cam-out and head damage. De-energize any electrical equipment before fastening or removing screws from panels, control boards, or enclosures, following NEC lockout/tagout procedures. Do not overtighten into tapped plastic or thin sheet metal; hand-tight plus a partial turn is typically sufficient. Use a thread-locking compound or lock nut if vibration is a concern in the application.
