Century Drill Tool 73205 No. 5 Square Flute Screw Extractor

Product Description

The CENTURY DRILL TOOL CO INC 73205 is a No. 5 square flute screw extractor designed to remove broken bolts and screws from fastening holes without damaging surrounding material. It removes bolts or screws up to 5/8 inches in diameter and is also rated for removing pipe fittings at 3/8 inches. The square flute design bites into the broken fastener as it turns counterclockwise, drawing it out cleanly. A 3/8-inch left-hand cobalt drill bit is recommended for the pilot hole. This tool is packaged in a set of 4 extractors and weighs 0.44 pounds total.

This extractor is well suited for thin-wall extraction applications where a standard extractor might crack or spread the surrounding material. Plumbers, HVAC technicians, electricians, and general trade professionals use screw extractors when a bolt or screw has sheared off flush or below the surface of the work piece. The 73205 is commonly used on pipe fittings, fasteners in metal brackets, equipment housings, and structural connections where a broken fastener blocks disassembly or replacement of components.
