Value Collection MPRI02502500-050B 1/4-20 Machine Screw 50pk

Product Description

The VALUE COLLECTION MPRI02502500-050B is a 1/4-20 threaded machine screw with a round head and Phillips drive, sized at 2.5 inches in length under head. Constructed from Grade 2 steel with a zinc-plated finish, this fastener is suited for general-purpose mechanical assembly in light- to medium-duty applications. The zinc coating provides basic corrosion resistance for indoor and sheltered environments. This screw conforms to ASME B18.6.3 dimensional standards. Sold in a minimum quantity of 50 per order, making it appropriate for production, maintenance, and repair work where consistent fastener supply is needed.

This screw is used in general mechanical and structural assemblies across HVAC equipment, electrical enclosures, plumbing fixtures, and light fabrication work. The Phillips round head profile sits above the work surface, distributing clamp load over a wider bearing area than flat head styles. The 1/4-20 unified coarse thread engages quickly and resists stripping in steel and threaded insert applications. Suitable for both shop and field installation by mechanical contractors, maintenance technicians, and fabricators.

Key Features

• 1/4-20 unified coarse thread for broad tooling and hardware compatibility
• 2.5-inch length under head suits medium-depth fastening applications
• Round head Phillips drive for standard screwdriver and bit compatibility
• Grade 2 steel construction for general-purpose mechanical strength
• Zinc-plated finish for basic corrosion resistance in sheltered environments
• Conforms to ASME B18.6.3 dimensional standards

Compatibility

Designed as a general-purpose 1/4-20 machine screw for use in any application requiring a round head Phillips fastener conforming to ASME B18.6.3 in inch measurement.

Installation Notes

Install with a No. 2 Phillips screwdriver or a 1/4-inch hex bit driver. Ensure the mating thread or nut is clean and free of debris before engagement to prevent cross-threading. Do not exceed the torque rating of Grade 2 fasteners; over-torquing can cause thread stripping or fastener failure. When used in electrical or HVAC enclosures, verify that fastener length and head profile comply with the equipment manufacturer's requirements.
