Irwin Industrial Tool Co 53405 Spiral Screw Extractor

Product Description

The IRWIN INDUSTRIAL TOOL CO 53405 is a size 5 spiral screw extractor designed to remove broken studs, bolts, socket screws, and fittings from metal workpieces. The tool features an aggressive left-hand spiral flute design that embeds itself deeper into the damaged fastener as turning resistance increases, creating a self-tightening grip the harder the fastener resists. Sized to handle bolts and screws from 3/8 inches to 5/8 inches, 1/4 inches NPT, 1/4 inches BSP, and 10 mm to 16 mm, it is used with a 19/64 inches pilot drill bit. This extractor is a go-to tool for HVAC techs, plumbers, and pipefitters dealing with seized or sheared hardware in tight mechanical assemblies.

This extractor is suited for residential and light commercial service work where broken fasteners need to be removed from cast iron, steel, and similar metal components. Typical applications include removing sheared bolts from flanges, fittings, and threaded pipe connections, as well as stripped socket screws in equipment housings. The left-hand spiral geometry means the extractor bites harder under load, making it effective in situations where conventional tools have already failed. This package contains 3 extractors per unit of measure.

Installation Notes

This tool is used by licensed HVAC technicians, plumbers, pipefitters, and electricians during repair and maintenance work. Before use, center-punch the broken fastener and drill a pilot hole with a 19/64 inches drill bit to the appropriate depth. Insert the extractor into the pilot hole and apply left-hand turning force using a tap wrench or locking pliers — do not apply excessive downward force, as this can cause the extractor to break inside the workpiece. Always wear appropriate eye protection when drilling and extracting broken fasteners.
