Description

Reverse Tapered Cutting Screw Thread

Square Head for use with Tapping Handles

5 Common sizes available

Technical data: 

Suits pilot drill: 7.5mm, 19/64" 

Suits bold thread diameter: 14 - 20mm, 9/16 - 3/4" 

Directions for use: 

1. If possible, grind or flatten the head of the damaged bolt or screw.

2. With a heavy hammer and centre punch, mark the centre of the bolt or screw; this will prevent the pilot drill wandering.

3. The extractor requires a pilot hole, start with a small Alpha left handed drill bit (e.g. 5/64’’).

4. If required, drill the hole out larger. It is best to use a left-hand drill for this step, as this may be enough to remove the stud without a screw extractor.

5. Select the correct size screw extractor for the hole.

6. With a tap wrench, turn the screw extractor into the hole in an anti-clockwise direction. The reverse threads force the extractor into the hole until the broken bolt or stud is forced to turn. Continue turning until the stud is removed.
