which tap?

[shanky887614]

i was going to be a better quality tap for threading stainless steal plates for 3.5mm pins

what pitch should i be looking for? some rethreaders are 0.6mm but im not sure what pitch or brand to go for (i have a ratchet tap wrentch)

edit.

for backboxes e.g. lightswitch/socket backbox

What screws do you want to use? If you want a standard metric 3.5mm thread the pitch is 0.6mm. If you want a metric fine 3.5mm it's 0.35mm pitch.

thought taps were in wet-pants' domain.

well we do have our resident plumber who will spot this shortly lol.

nah bassically a 3mm rethreader similar to the ones made by ck etc but stronger so they can do stainless steel blank plates

If you need stronger you're probably misusing it. Rather go with a taper tap first and a final tap afterwards. 3.5MM HAND TAPS - 18075 - DRAPER TOOLS

If you drill the correct size hole and use a dab of oil you can use these taps with your battery drill on low speed.

its in stainless steel marvo and the tap i picked up was a cheap terrible brand but i really needed one at the time and it was the only place open.

Any respectable brand of taps will work in stainless 3CR12, 304, 316 etc unless maybe if it's s/s 440 blade grade or similar. Two tap draper set will be fine for general s/steel plate for decorative covers and enclosures.

Dormer is a good make for taps

Might be a bit of a squeeze getting his M3.5 screws in though

File them down a bit!!

It's easy enough to search the same spec tap but with a different size though.

Fact is I'm struggling a bit to see nowadays cos I'm waiting for an eye operation. I'm actually looking at this lappy through a magnifying glass!!

It's ridiculous.

Thanks lads!

The daft thing is I used to know those little tricks but somehow seem to have forgotten them - and other things as well - like the other day I decided to fire my Celeica up just to swirl the oil around a bit and couldn't understand why it wouldn't fire up.

I had forgotten about the immobiliser .....
