When reliable, tamper-resistant fastening matters for security and surveillance hardware, the Dottie DDSMS122 Sheet Metal Screw delivers. Designed for mounting cameras, enclosures, racks and networking components, this #12 screw offers a 2in length and a stout 0.425–0.407" diameter to provide strong bite into sheet metal, wood or plastic.
