Sizing issues

[Sithlord]

Hi guys,,

Maybe this has been asked before but how do you work out the sizes for nuts/bolts/washers etc..

Found a workshop today that manufactures aerospace grade 5 Ti (6/4) bits n bobs to order.. theres a few bolts and washer that I would like to change over to Ti but not sure on how to work out the sizes I need..

Anyone help on this..

Si

Do you mean thread sizes? ie M5, M6 etc

Measure the diameter of the thread. (screw bit) You shouldnt need to know the pitch as they are standard ( there are some options in some sizes, but they are not commonly used, especially on bikes)

all you should need to give is the diameter & length. eg. M5x25mm

Have a look at INOX fasteners....everything you need to know about fasteners
Have a look at the PDF Catalogue...just a few pages in gives details of how to measure bolts etc etc

3mm allen key = M4 thread (jockey wheel bolts)
4mm allen key = M5 thread (bottle cages etc)
5mm allen key = M6 thread (SFN bolt,canti's)

Thanks guys , much appreciated... If anyone else is after any bolts etc, let me know as It will be cheaper for all if its one order

After talking to the guy at the Ti workshop, he seems to be willing to manufacture most things out of Ti, not sure of prices or quality yet...

But sounds promising...



Just think.... Ti Custom stems/cranks . mmm
