Value Collection MSRI0-200370-100BX Machine Screw 2-56

Product Description

The VALUE COLLECTION MSRI0-200370-100BX is a 2-56 UNC machine screw with a round head and slotted drive, manufactured from alloy steel with a zinc-plated finish. The screw measures 3/8 inches in length under the head and is sold in a box quantity of 100 pieces per order. The zinc plating provides basic corrosion resistance for general-purpose fastening applications in light to moderate environments. This fastener is installed by electricians, HVAC technicians, sheet metal workers, and maintenance professionals requiring a small-diameter, fine-threaded screw for panel assemblies, electrical enclosures, and equipment housings.

This screw is suited for light-duty fastening tasks in residential and commercial applications where a compact, slotted round-head fastener is required. Common installation scenarios include securing terminal blocks, control panel components, light sheet metal brackets, and small equipment covers. The 2-56 thread designation and inch-system sizing make this screw compatible with standard tapped holes found in electrical and electronic equipment manufactured to UNC inch-standard specifications. No washer is included or required by the design.

Key Features

• 2-56 UNC thread for compatibility with standard inch-system tapped holes in electrical and electronic assemblies
• Round head profile provides a low-profile, finished appearance on panel and enclosure surfaces
• Slotted drive accommodates flat-blade screwdrivers for straightforward installation in confined spaces
• Alloy steel construction delivers strength appropriate for light to moderate clamping loads
• Zinc-plated finish offers basic corrosion resistance in indoor and sheltered environments
• Sold in a 100-piece box quantity to support production, service fleet, and shop stock requirements

Compatibility

Designed for use in any application requiring a 2-56 UNC inch-thread machine screw with a round head and slotted drive, including electrical enclosures, control panels, terminal boards, and light-gauge sheet metal assemblies.

Installation Notes

Install with a flat-blade screwdriver sized to fit the slot without slipping, which can damage the head or surrounding surfaces. Verify the receiving hole is tapped to 2-56 UNC specification before driving to avoid cross-threading. Do not exceed the torque capacity of the 2-56 thread; alloy steel screws at this diameter are susceptible to shank failure if over-torqued. When used in electrical panels or enclosures, follow applicable NEC requirements for fastener access and panel integrity.
