Value Collection MSRI-1202500-050B 12-24 X 2-1/2 in Round Head Screw

Product Description

The VALUE COLLECTION MSRI-1202500-050B is a 12-24 UNC machine screw with a round head and slotted drive, designed for general mechanical fastening applications. The fastener is manufactured from alloy steel and finished with a zinc coating for basic corrosion resistance. The shank measures 2-1/2 inches in length under the head, conforming to the inch system of measurement. This screw is sized at 12-24, indicating a number 12 diameter with 24 threads per inch. It is sold in lots with a minimum order quantity of 50 pieces per package. Installers and maintenance technicians working on light machinery, electrical enclosures, HVAC panels, and similar assemblies commonly use this fastener type.

This screw is appropriate for indoor mechanical assemblies where a standard zinc finish provides adequate protection against light oxidation. The round head profile seats flush to the surface without countersinking, making it suitable for through-hole applications in sheet metal, plastic, or light structural components. The slotted drive allows installation with a standard flathead screwdriver, which is common in service environments where Phillips or hex tools may not be available. This fastener is packaged as a single unit with a 50-piece minimum order quantity, suited to both stock replenishment and project-based procurement.

Installation Notes

Installation is performed with a standard flathead screwdriver sized to the screw head. Pre-drilled or tapped holes should match the 12-24 UNC thread specification before driving the fastener. Avoid over-torquing, which can strip threads or fracture the fastener in thin-material applications. Power down any electrical equipment before servicing panels or enclosures that require this fastener type.
