Value Collection MSCI0-200250-100BX Machine Screw 2-56

Product Description

The VALUE COLLECTION MSCI0-200250-100BX is a 2-56 UNC machine screw with a fillister head and slotted drive, sold in a box of 100. The screw measures 1/4 inch in length under the head and is manufactured from Grade 2 steel with a zinc-plated finish for basic corrosion resistance. Fillister heads feature a small-diameter, tall cylindrical profile that fits into counterbored holes and provides good bearing surface for slotted drivers. These are general-purpose fasteners suitable for light-duty mechanical assemblies where the #2-56 thread size is specified.

These machine screws are used in light mechanical and electrical assemblies where small-diameter, fine-threaded fasteners are required. Typical applications include panel mounting, instrument enclosures, light fixtures, small motors, and electronic chassis work. The slotted drive is compatible with standard flat-blade screwdrivers, making them accessible in field and shop environments. The zinc plating provides a baseline level of protection against oxidation in dry indoor conditions.

Key Features

• 2-56 UNC thread — fine pitch suitable for thin panels and precision assemblies
• Fillister head profile fits counterbored holes and provides a tall grip surface for slotted drivers
• Grade 2 steel construction for general-purpose mechanical strength
• Zinc-plated finish for basic corrosion resistance in dry indoor environments
• 1/4 inch length under head — compact size for shallow fastening applications
• Sold in a box of 100, minimum order quantity of 100 units

Compatibility

Designed as a standard inch-series machine screw for use in any application calling for a 2-56 UNC thread, 1/4 inch length, fillister head, slotted drive fastener per inch-system specifications.

Installation Notes

Install using a flat-blade screwdriver sized to fit the slot without slipping, which can damage the head or surrounding material. For electronic and instrument enclosures, de-energize the assembly before fastener work. Do not overtighten Grade 2 steel screws in soft or tapped plastic materials, as the threads strip easily at small diameters. Follow the equipment manufacturer's torque guidance when specified.
