Thread for Wingnut LM175

Hello all. Does anyone happen to know what thread size the wingnut is for pushhandle on an LM175 or MM275?

the wingnut part number is 243573-00. the bolt is 241947-01.

I have been to B&W's part site however they don't list the thread in the description. Neither does any other parts site, if I search the web for the part number. I know I can bring the bolt to a local store and check it out. I just keep forgetting to put it in my car .

The wingnut is used on other equipment. I think it's a 5/16. It's part number 18

its 5/16 - 18 TPI.

I feel stupid now. I didn't notice the note on Black and Decker's parts site actually shows the thread size for the bolt and nut.



It just so happens I had to replace some hardware on a bench grinder stand. The wing nut from that is the same thread.
