ALPHA SCREW EXTRACTOR NO.4 (8.33MM)

Description

Reverse Tapered Cutting Screw Thread

Square Head for use with Tapping Handles

5 Common sizes available

Technical data: 

Suits pilot drill: 6.35mm, 1/4" 

Suits bold thread diameter: 10 - 12mm, 3/8 - 1/2" 

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.

 

For critical applications, please check with the manufacturer as specifications can change without notice.
