Value Collection MPPI02502250-100BX Machine Screw 1/4-20

Product Description

The VALUE COLLECTION MPPI02502250-100BX is a 1/4-20 x 2.25-inch pan head machine screw designed for general-purpose fastening in metal, wood, and composite materials. Manufactured from Grade 2 steel with a zinc finish for basic corrosion resistance, these screws feature a Phillips drive for quick installation with standard power or hand tools. The 1/4-20 UNC thread designation indicates a unified coarse thread pattern, which provides solid holding power in a wide range of tapped holes and nuts. This box contains 100 screws, making it a practical quantity for service vehicles, shop stock, or project-level use. Suitable for installation by electricians, HVAC technicians, plumbers, general contractors, and maintenance professionals.

These machine screws are appropriate for light-to-medium duty fastening applications across residential and commercial settings. Common uses include panel assembly, equipment mounting, junction box work, and general mechanical assembly where a 1/4-20 UNC threaded connection is specified. The pan head profile offers a low-profile, wide bearing surface that distributes clamping load evenly without requiring a washer. The zinc coating provides a baseline level of protection against oxidation in dry indoor environments. This screw is sold without a washer and is measured length-under-head per standard fastener convention.

Installation Notes

Install using a Phillips No. 2 screwdriver or a compatible power driver bit. Always ensure the mating thread or nut is fully engaged before applying torque to avoid cross-threading. De-energize any electrical equipment and follow applicable NEC or OSHA lockout-tagout procedures before fastening within live panels or enclosures. Zinc-finished Grade 2 screws are intended for dry indoor environments and should not be used in wet or corrosive locations without additional protection.
