How to extract a screw or bolt using straight fluted extractors?
Equipment you will need:
You will need these tools to extract a broken, damaged or embedded screw with the straight fluted extractors:
Power drill (set to reverse) or manual screwdriver with a hexagonal slot
Straight fluted screw extractor
Screwdriver or drill?
If the fastener is badly damaged, you may wish to use a screwdriver to give you more control when turning the extractor.
A drill will give you more power when extracting, however, it can be easy to lose control of the tool and damage the fastener even more.
Step 1 – Attach extractor to tool
Place the extractor in your chosen tool. The screwdriver will have a magnetic slot in which you can insert the extractor.
Step 2 – Centre extractor
Place the tip of the extractor in the centre of the screw. It will have a self-centering tip so there’s no need to use a punch, or make a pilot hole.
Step 3 – Turn extractor
Begin rotating the extractor anti-clockwise to dig it into the head of the damaged, embedded or broken screw. Keep turning, applying an even pressure until the extractor digs into the screw and starts turning the screw with it.
Make sure you apply pressure evenly when pushing the extractor against the screw, this will keep it in the centre to avoid any further damage.
Step 4 – Remove screw
Keep turning the screwdriver or pressing the trigger of the drill until the screw has emerged and can be completely removed.
