Value Collection MPRI02500370-100BX 1/4-20 X 3/8 in Screw

Product Description

The VALUE COLLECTION MPRI02500370-100BX is a 1/4-20 x 3/8 inch round head Phillips machine screw sold in a 100-piece pack. Made from Grade 2 steel with a zinc plating for corrosion resistance, this fastener is threaded to Unified National Coarse (UNC) standards. Length is measured under the head at 3/8 inches. The round head profile sits above the work surface and accepts a standard Phillips driver. These screws are a general-purpose fastener used by electricians, HVAC technicians, plumbers, and other trades wherever a 1/4-20 UNC thread pattern is required.

Typical applications include panel mounting, equipment housings, junction boxes, HVAC unit assembly, and general mechanical assembly where a 1/4-20 coarse thread is specified. The zinc plating provides a measure of protection in light-duty indoor or sheltered outdoor environments. The 100-piece pack quantity suits service vans, shop stock, and job-site use where consistent fastener availability matters.

Installation Notes

Install using a Phillips screwdriver or Phillips-bit power driver sized for a 1/4-20 fastener. De-energize any electrical equipment before installing fasteners in or near live panels, following applicable NEC guidelines. Do not overtighten into plastic housings or thin-gauge sheet metal, as Grade 2 steel can strip soft substrates. Inspect threads and mating tapped holes for damage before installation to ensure full thread engagement.
