Screw extractor for large bolts
This Westward spiral-flute extractor removes damaged right-hand threaded bolts from 1 in. to 1-3/8 in. diameter. The 17/32 in. drill size prepares the hole before the extractor engages. High-speed steel construction resists wear during heavy-duty removal tasks. It suits maintenance crews and machinists who encounter seized large fasteners.
Upgrade from straight-flute tools
Spiral flutes bite deeper as torque increases, reducing the chance of the extractor slipping or snapping in stubborn bolts. The square drive accepts a standard wrench or tap handle for controlled leverage. The jump is worth it when straight-flute extractors have already failed or when bolt material is particularly hard.
Limits of spiral-flute extraction
The tool only works on right-hand threads and requires a precisely drilled 17/32 in. hole; an off-centre or oversized hole will cause failure. The .602 in. square drive limits the maximum torque you can apply without a dedicated holder. Extremely corroded or heat-treated bolts may still require heat or a different removal method.

Questions about this item
What drill size does the size 7 spiral-flute extractor require?
The extractor is designed for a 17/32 in drill bit to create the pilot hole before extraction.
How do I engage the square drive on this extractor?
Fit a 0.602 in square-drive wrench or socket onto the extractor's drive end and turn counter-clockwise; the spiral flutes bite as you apply steady torque.
When should I replace this high-speed-steel extractor?
Replace it once the spiral flutes show visible rounding or chipping, as dull flutes lose grip on right-hand threaded bolts between 1 in and 1-3/8 in.
