Stewart Fastener MDB-08 Magnetic Nut Setter 1/4 in Drive

Product Description

The STEWART FASTENER MDB-08 is a magnetic nut setter designed for fast, secure fastener driving in trade and construction applications. With a 1/4 inch hex drive shank and an overall length of 2-9/16 inches, this tool accepts standard 1/4 inch nuts and hex-head fasteners and holds them magnetically for one-handed placement. The built-in magnet retains the fastener during drive, reducing fumbling on the job and keeping work moving on confined or overhead installations. HVAC installers, electricians, plumbers, and general contractors keep this type of setter on hand for sheet metal screws, hex-head sheet metal fasteners, and equipment panel work.

This nut setter is suited for use with power drills and impact drivers featuring a 1/4 inch hex chuck. It is a practical everyday driver for residential and light commercial work where repeated fastener driving is required. Common applications include ductwork assembly, electrical panel and enclosure work, equipment mounting, and sheet metal fabrication where magnetic retention speeds up production and minimizes dropped hardware.

Installation Notes

This tool is installed into any 1/4 inch quick-change or keyed hex chuck without additional hardware. Ensure the driver is powered off and the chuck is secure before inserting or removing the setter.
