That's certainly the commonly accepted difference David, but it's not how they're described in the industry.

To be even more technically correct - it's a Machine Screw.

Engineering students are taught never to use words like screw, saw, or hammer, without an accompanying adjective to define it.

Hi

A bolt that has threads all the way to the head is called a SET SCREW

My 1.8s bleed screw is a 6 mm set screw and in my opinion is a poor design

It should have a hole drilled up the centre to the half way point and then be cross drilled so the screw does not have to be completely removed to bleed the system .

Regards

Steve

At last, someone has got the name right!

Hi Guys,

Where can the bleed screw be found? (Sorry)

Thanks,

Iain

Hi Iain and

along!

It's bonded into a radiator hose which you will see near the battery. Look for a hexagon head.

Sean has now sent me one with the washer & seal which I didn't have before. Not sure if it will make any difference, but every little helps....
