Screw Extractor #7 for Large Bolts
This Westward spiral-flute extractor removes right-hand threaded bolts from 1-1/8 to 1-1/2 inches. It is machined from high-speed steel for hardness and wear resistance. The square drive measures 0.709 inches for use with a wrench or tap handle. Overall length is 4 1/8 inches.
Drill Size and Bolt Range Limits
The tool requires a 39/64 inch pilot hole drilled into the broken fastener. It only fits bolts within the stated 1-1/8 to 1-1/2 inch diameter range. Smaller or larger bolts need a different extractor number. Left-hand threaded fasteners cannot be removed with this right-hand spiral design.
Spiral Flute Geometry Determines Fit
The #7 spiral flute configuration is the single specification that matches this extractor to the bolt size and drill diameter listed. Using the correct extractor number prevents further damage to the workpiece. Buyers who need a different bolt range or left-hand thread removal must select another tool.

Questions about this item
Should I choose the #7 spiral-flute extractor or a different size for a 1-1/8 to 1-1/2 bolt?
The #7 spiral-flute extractor is made for bolts from 1-1/8 to 1-1/2 and uses a 39/64 in drill size, so match it to that bolt range.
What does the 39/64 in drill size mean when I use the extractor in a real job?
Drill a 39/64 in hole in the broken fastener, then drive the extractor with its square drive to grip and back the bolt out.
How does the 0.709 in square drive limit the tools I can use with this extractor?
The 0.709 in square drive fits a matching tap wrench or socket, so you need a driver with that exact square opening.
