What is this instument for?

[Pampurrs]

I received my magnetic oil drain plugs from Dimple Plugs, and the package included a gift of this handy little metric ruler. However, I've never seen anything like this "sawtooth" part on the top. Does anyone know what this is used for? :dontknow:

Thanks,

Pam

Metric thread pitch

Interesting. Possibly to measure thread in metric although it looks like pretty course thread. Holes in the center are to measure diameter of bolt or plugs.

Metric thread pitch

Ah yes, that makes sense. Thanks! :bowdown:

Agree...

:agree: you can put any bolt or screw up aginst the teeth and if they match then you know what to look for at you local store. Handy little tool. I have several and when I got this one I just hung it on the wall and use it the most. But then you will find in the bike industry the most common ar the 1.0, 1.25, 1.50...:thumbup:

Yeah, I knew what the holes are for, I was just perplexed about the upper edge. Thread pitch measure it is.

Thanks!

I've seen gauges made for this purpose; but not like the one that you've pictured.
Thanks for posting it! :thumbup:

It's for killing metric zombies

 

[SPYDERGUY1]

Yup, it is a thread pitch guage to tell you what type of bolt/fastener you need. The holes will tell you the size of the fastener. Very handy at times unless you get into EUROPEN METRIC, then all is gone and lost. Different system altogether.

Thank you

Thank you everyone who answered my question. That's a handy little item indeed.
