BK16 hex nuts

[filedog]

What the heck size are these nuts?? They're between 3 an 4 mm,
also between 1/8 and 3/32. Guess that's why they're called tweeners :biggrin:

Neither 4mm nor 5/32 fit, so they're not the same as they're bigger brethren.

Its a 9/64.

Yeah, I should have been more clear it was the size of the allen wrench I needed, thanks!

There is a standard torx bit that fits them perfectly as well, like a 15 or 20 I think. Might be easier to come by.

nuts? you mean the bolt heads? yeah, they're a weird one

not necessarily in the database, as they are different from standards Beckers (and historically we've seen some variation in SAE and metric, and sizes, and ...)
