Value Collection MSRI-1201500-100BX Machine Screw 100-pack

Product Description

The VALUE COLLECTION MSRI-1201500-100BX is a 12-24 UNC machine screw with a round head and slotted drive, sold in a box of 100. Constructed from alloy steel with a zinc-plated finish, these fasteners deliver solid corrosion resistance for general mechanical and structural assembly work. The screw measures 1.5 inches in length under the head and uses a #12-24 unified coarse thread form. The round head profile sits above the mating surface and is driven with a standard flat-blade screwdriver. Electricians, HVAC installers, equipment assemblers, and maintenance technicians commonly use this screw size for panel mounting, bracket attachment, and light structural connections.

This screw is suited for a wide range of light-to-medium-duty fastening applications in residential, commercial, and industrial settings. Common uses include mounting electrical enclosures, attaching HVAC control panels, securing equipment brackets, and general sheet-metal or structural assembly where a UNC thread pattern and round-head profile are specified. The zinc plating makes these screws appropriate for indoor applications and moderately controlled environments where mild corrosion resistance is required.

Key Features

• 12-24 UNC thread for broad compatibility with standard tapped holes and hex nuts
• 1.5-inch length under head suits a range of material stack thicknesses
• Round head profile provides a low-profile finished appearance above the work surface
• Slotted drive works with standard flat-blade screwdrivers and bits
• Alloy steel construction offers greater tensile strength than low-carbon alternatives
• Zinc plating provides corrosion resistance for indoor and controlled-environment use

Compatibility

Designed as a general-purpose UNC machine screw for use in any application requiring a #12-24 thread, round head, and slotted drive in a 1.5-inch under-head length.

Installation Notes

Install using a flat-blade screwdriver or slotted bit sized to match the head slot. Ensure the mating hole is tapped or threaded to #12-24 UNC specification before driving. De-energize any electrical equipment before inserting fasteners into or near live panels, in accordance with NFPA 70 lockout/tagout procedures. Do not overtighten; apply torque appropriate to the base material to avoid stripping the thread or cracking the mating surface.
