Value Collection 312-8927 Spiral Flute Screw Extractor Size 7

Product Description

The VALUE COLLECTION 312-8927 is a Size 7 spiral flute screw extractor designed to remove broken, stripped, or seized screws and fasteners in the 7/8 to 1-1/8 inch range. The spiral flute design bites into damaged fastener material as reverse torque is applied, drawing the broken piece out of the workpiece. At 4.125 inches overall length, the tool provides adequate reach for recessed fasteners. It weighs 0.05 pounds. Electricians, plumbers, HVAC technicians, and general maintenance mechanics use this type of extractor when a fastener head has failed beyond the reach of a standard driver or wrench.

This extractor is suited for use on broken bolts, studs, and pipe plugs across a range of applications. Compatible screw and fastener sizes include 22 to 27 mm, 7/8 to 1-1/8 inches, M22 to M27 metric, 1/2 inch NPT, and 1/2 inch BSP. It is appropriate for use in residential and light commercial maintenance, mechanical repair, plumbing rough-in, and HVAC service work where fastener removal is required without damaging the surrounding material.

Designed for broken or damaged screws, bolts, and pipe plugs in the 22 to 27 mm and 7/8 to 1-1/8 inch size range, including 1/2 inch NPT and 1/2 inch BSP fittings, and M22 to M27 metric fasteners.

Installation Notes

A licensed mechanic, plumber, or HVAC technician typically handles broken fastener extraction in professional service settings. Before beginning, ensure the workpiece is secured and power tools or energized systems in the area are shut down. Drill a pilot hole into the center of the broken fastener using the appropriate left-hand drill bit size before inserting the extractor. Apply steady reverse-rotation torque with a tap wrench or appropriately sized driver to avoid snapping the extractor in the bore.
