Century Drill Tool 73414 6-piece Spiral Screw Extractor Set

Product Description

The CENTURY DRILL TOOL CO INC 73414 is a 6-piece spiral flute screw extractor set designed to remove broken screws and bolts that have snapped off flush inside a fastening hole. The set includes sizes 1 through 6, giving technicians a range of extractor diameters to match common broken fastener situations. Each extractor uses a left-hand spiral flute profile that bites aggressively into the damaged fastener as it turns counterclockwise, converting rotational force into extraction force. This set is a standard tool for HVAC techs, plumbers, electricians, and general trade professionals who regularly encounter seized or broken hardware during service calls.

Spiral flute extractors are used across residential and commercial service work wherever fasteners break off during removal or installation. Common scenarios include stripped machine screws in electrical panels, broken cap screws on HVAC equipment housings, and snapped bolts on pipe flanges or valve bodies. The 73414 set covers a wide range of broken fastener sizes in a single kit, making it practical for field service bags and shop toolboxes alike.

Installation Notes

Spiral flute screw extractors are installed by licensed tradespeople and experienced service technicians. Before using an extractor, power down equipment and relieve any system pressure per applicable codes including NEC, IPC, or IFGC as relevant to the work. Drill a pilot hole into the center of the broken fastener using the correct drill bit size for the extractor being used, then insert the extractor and turn counterclockwise with a tap wrench or appropriately sized driver. Do not apply excessive side load or impact force to the extractor, as extractors are hardened and can fracture if overloaded.
