Value Collection MSRI-1202500-100BX Machine Screw 100-pack

Product Description

The VALUE COLLECTION MSRI-1202500-100BX is a 12-24 x 2-1/2 inch round head slotted machine screw sold in a 100-piece box. Manufactured from alloy steel with a zinc-plated finish, this fastener is built for corrosion resistance and mechanical strength in standard trade and industrial assembly applications. The unified national coarse (UNC) thread form is the most common inch-series thread standard in North American mechanical work. Length is measured under the head at 2-1/2 inches. These screws are installed by maintenance technicians, electricians, plumbers, HVAC service professionals, and general tradespeople who need a reliable, off-the-shelf inch-series fastener.

This machine screw is suited for light to medium-duty mechanical assembly, panel attachment, equipment mounting, and general fastening tasks across residential, commercial, and light industrial settings. The round head profile provides a low-profile bearing surface without requiring a countersunk hole, making it appropriate for through-hole applications in sheet metal, plastic housings, electrical enclosures, and equipment frames. The slotted drive accepts a standard flat-blade screwdriver. The 100-piece box format supports both service van stock and shop inventory.

Key Features

• 12-24 UNC thread for compatibility with standard inch-series tapped holes
• 2-1/2 inch length under head for reach in thicker assemblies
• Round head profile suits through-hole and clearance-hole applications
• Slotted drive accepts flat-blade screwdrivers and bits
• Alloy steel construction provides mechanical strength over mild steel
• Zinc-plated finish adds corrosion resistance for indoor and light-exposure environments

Compatibility

Designed for use in any application requiring a 12-24 UNC inch-series machine screw with a round slotted head. Fits standard 12-24 tapped holes and clearance-drilled assemblies per inch-series fastener specifications.

Installation Notes

Installation is performed by hand with a flat-blade screwdriver or bit driver. Ensure the mating tapped hole is clean and free of debris before driving. Do not overtighten, as alloy steel screws in softer base materials can strip threads. Power down or de-energize any electrical enclosure or control panel before fastening screws into live equipment.
