Century Drill Tool 73215 Square Screw Extractor Set 5 Piece

Product Description

The CENTURY DRILL TOOL CO INC 73215 is a 5-piece square screw extractor set designed to remove broken screws and bolts that have snapped off inside a fastening hole. Each extractor in the set uses a square, tapered profile that bites into the broken fastener as it is turned counterclockwise, applying outward gripping force to back the fastener out. The set covers a removal range of 3/16 inches to 5/8 inches in broken bolt or screw diameter. The complete set weighs 1.44 pounds. This tool is a standard item in the kits of electricians, plumbers, HVAC technicians, and general maintenance professionals who encounter broken fasteners in the field.

Square screw extractors are used across residential and commercial service work wherever a fastener has sheared or snapped flush with or below a surface. Typical applications include removing broken machine screws from equipment panels, broken bolts from pipe flanges, and stripped or snapped screws from structural connections. The graduated set of five extractors allows the technician to match the correct extractor size to the diameter of the broken fastener without overstressing the material around the hole.

Installation Notes

Square screw extractors are typically used by any trade professional who services mechanical, electrical, or plumbing systems. Before extraction, a pilot hole must be drilled into the center of the broken fastener using an appropriate drill bit; always ensure the workpiece is secured before drilling. Power down or de-energize any equipment before attempting fastener removal near live components. Use a tap wrench or a suitable driver to turn the extractor counterclockwise with controlled, steady pressure to avoid snapping the extractor inside the hole.
