Value Collection 312-8923 Spiral Flute Screw Extractor Size 3

Product Description

The VALUE COLLECTION 312-8923 is a Size 3 spiral flute screw extractor designed to remove broken or seized screws from metal, wood, and composite materials. The spiral flute design bites into damaged fastener heads as reverse torque is applied, drawing the broken screw out without damaging the surrounding material. Compatible with screws in the 7/32 to 9/32 inch range, including 6 to 8 mm metric equivalents and Number 12 fasteners. At 2-11/16 inches overall length, it fits standard extraction drill setups. Installed by machinists, maintenance techs, and general tradespeople working on equipment, fixtures, or structural assemblies where fastener removal is required.

This extractor is suited for repair and maintenance tasks across industrial, commercial, and residential settings. It is typically used when a screw head has been stripped, broken flush, or snapped below the surface. The Size 3 designation makes it appropriate for medium-range fasteners commonly found in HVAC equipment panels, electrical enclosures, plumbing fixtures, and general mechanical assemblies. A pilot hole is drilled into the broken fastener before the extractor is driven in counterclockwise to grip and back out the damaged screw.

Installation Notes

A licensed machinist or experienced tradesperson should perform fastener extraction on precision or load-bearing assemblies. Before use, shut off or de-energize any equipment the fastener is securing. Drill a pilot hole into the center of the broken fastener using an appropriately sized left-hand drill bit before inserting the extractor. Apply steady reverse torque — do not force the extractor, as excessive pressure can cause breakage inside the workpiece.
