Thread: HELP with tap sizes!

5/32" Whitworth (BSW) 32 TPI (Threads Per Inch).

ElDubya,

5/32W is 5/32" Whitworth thread, 32 TPI. It used to be very common for things like drawer pulls etc. Thinking a long way back, I seem to remember it was also used on the spokes on the wire wheels on the old Austin 7 cars. 3/32.W, 5/32W and 7/32W threads were all fairly common for small screws years ago, but 5/32 seems to be the only one which survived in common use until recently.

Edit: Chris beat me to it!

Here's a simple chart for you.

I bought some brass screws from Bunnings today for a project I am working on, in a 5/32. Now, knowing next to bugger all about threads and thread pitches, etc can someone tell me what this means :

5/32" W32

In this case the w32 means whitworth but a lot of brass nuts and bolts have a standard of 26tpi.

Next time you are near an industrial supplies shop get yourself a Tap and drill chart. Often free if you are buying something else, and it will give you all of the different sizes and threads available. Bunnings wont stock most of them.
