Value Collection 312-8930 Spiral Flute Screw Extractor Size 10

Product Description

The VALUE COLLECTION 312-8930 is a Size 10 spiral flute screw extractor designed to remove broken, stripped, or seized screws and fasteners in the 2-1/8 to 2-1/2 inch range. The left-hand spiral flute design bites into the damaged fastener as reverse torque is applied, drawing it out without damaging the surrounding material. At 5 inches overall length, this extractor provides sufficient reach for deep-set fasteners encountered in mechanical, plumbing, and general maintenance work. It is a standard hand-tool item used by plumbers, pipefitters, machinists, and maintenance technicians across commercial and industrial settings.

This extractor is suited for removing broken fasteners in residential and commercial applications wherever large-diameter screws or threaded pipe fittings have seized or sheared. The compatible screw size range of 2-1/8 to 2-1/2 inches also covers 1-1/4 inch NPT and 1-1/4 inch BSP threaded pipe connections, as well as metric fasteners in the M52 to M68 range. It is a practical addition to a field kit for plumbers dealing with stuck pipe fittings or machinists working on heavy equipment fasteners.

Installation Notes

Screw extractors are typically used by machinists, plumbers, and pipefitters working on mechanical or pipe assemblies. Before attempting extraction, drill a pilot hole into the center of the broken fastener using the appropriate bit size for a Size 10 extractor. Insert the extractor and apply steady counterclockwise torque using a tap wrench or appropriately sized chuck. Do not apply excessive side-load or hammer the extractor, as spiral flute extractors can fracture under shock loading and become more difficult to remove than the original fastener.
