Screw Extractor Kits | ||||||||||||||||||||||||||||||||||
| Screw extractors can be purchased individually or in a set of different sizes. Information about the size and number of screw extractors can usually be found on the product data sheet or on the packaging. Sometimes the size of the screw extractor, and even the size of the screw it can remove, is laser engraved or engraved on the side of the extractor. | ||||||||||||||||||||||||||||||||||

| The size of the screw or bolt that can be removed is directly related to the size of the extractor. Examples are microspiral flute extractors with drilled ends and spiral flute extractors with drilled ends. Both do the same job, however the size of each makes them suitable for different sized screws and bolts. | |||||||||||||||||||||||||||||||||
 | Screw size is represented by a number from 0 to 24. Screw extractors are sized according to the number of screws they can remove. The following table shows the various shank diameter measurements in inches (fractional and decimal) and millimeters. The shank diameter is measured from the smooth part just above the thread. | |||||||||||||||||||||||||||||||||
 | If the screw is recessed, you can place the end of the extractor against the screw or bolt to see if it fits. You can even drill a pilot hole with a small drill bit about 1.5 mm (1/16 in.) or 3 mm (1/8 in.) in diameter and check the end of the extractor in the pre-drilled hole. | |||||||||||||||||||||||||||||||||
