Odd design of the Tiger Pro shaft with screw visible

[hang-the-9]

I recently looked at a Tiger Pro shaft, it's pretty heavy at over 4 oz, when looking down the shaft you can see a glint of a screw at the bottom of the joint. Is this common at all with shaft construction? This is probably the heaviest shaft I have touched and the only one I remember having a screw in it.

I've seen several shafts like that from Tiger, so I think it's the way they make sure the shafts have an even weight.

Will it show in a photo?

Old Brunswick cues had screws there. In the butt and in the shaft.

I weighed a customers Revo 12.9mm the other day, it was 4.3oz. I compared it to 2 cf shafts I made from blanks which were 12mm (3.1oz) and 13mm (3.4oz) . Was quite a surprise to me
