Value Collection MPRI02501750-050B 1/4-20 Machine Screw 50-pack

Product Description

The VALUE COLLECTION MPRI02501750-050B is a 1/4-20 UNC machine screw measuring 1-3/4 inches in length under head, featuring a round head with a Phillips drive. Manufactured from Grade 2 steel with a zinc plating finish, this screw is suited for general-purpose fastening in light-duty mechanical and structural assemblies. Sold in a minimum order quantity of 50 pieces, it is a practical choice for maintenance technicians, electricians, plumbers, and HVAC installers who need a reliable standard fastener for panel mounting, equipment enclosures, and fixture attachment.

This screw is appropriate for a wide range of trade and light industrial applications where inch-system fasteners are specified. The 1/4-20 thread designation is one of the most common coarse-thread sizes in North American trade work, appearing in electrical panels, HVAC equipment frames, junction boxes, and plumbing fixture brackets. The zinc plating provides basic corrosion resistance for indoor and protected-environment installations. These screws are well suited for production assembly lines, service van stock, and general shop inventory.

Installation Notes

Install using a Phillips-head screwdriver or bit driver sized for the fastener. Do not overtighten Grade 2 fasteners, as they have lower tensile strength than Grade 5 or Grade 8 hardware. Power down or de-energize any equipment before installing screws in or near electrical enclosures, per applicable NEC requirements. Verify thread engagement depth before applying torque to avoid stripping the receiving material.
