Value Collection MSCI02503000-050BX Machine Screw 1/4-20

Product Description

The VALUE COLLECTION MSCI02503000-050BX is a 1/4-20 UNC machine screw with a fillister head and slotted drive, manufactured from Grade 2 steel with a zinc-plated finish. Measuring 3 inches in length under the head, this fastener is designed for general-purpose mechanical assembly where a tall, cylindrical head profile is needed to provide extra bearing surface and recess depth for a slotted driver. The zinc plating offers basic corrosion resistance suitable for indoor and light-duty applications. Sold in a minimum quantity of 50 pieces per order.

This fastener is used across a wide range of trade and light industrial applications including HVAC equipment assembly, electrical enclosure fabrication, plumbing fixture mounting, and general mechanical maintenance. The fillister head profile is commonly specified where a raised head with a deep slot is preferred over flat or pan head styles. The 1/4-20 UNC thread is one of the most common inch-series thread standards, making this screw a straightforward replacement or stock fastener for service technicians and assembly crews working on standard equipment.

Key Features

• 1/4-20 UNC thread form for broad compatibility with standard inch-series tapped holes
• Fillister head profile provides a tall, cylindrical head with extra driver-recess depth
• Slotted drive compatible with standard flat-blade screwdrivers
• Grade 2 steel construction meets general-purpose mechanical fastening requirements
• Zinc-plated finish for basic corrosion resistance in indoor or sheltered environments
• 3-inch length measured under the head per standard length measurement convention

Compatibility

Designed as a general-purpose inch-series machine screw for use in any application requiring a 1/4-20 UNC threaded fastener with a fillister head profile and slotted drive.

Installation Notes

Install with a flat-blade screwdriver sized to fit the slot properly to avoid cam-out and head damage. Ensure the mating tapped hole or nut is 1/4-20 UNC thread form before installation. De-energize and isolate any equipment before fastening components inside electrical or mechanical enclosures. Do not overtighten Grade 2 steel fasteners in softer base materials such as aluminum or plastic.
