Can I use a 9/32" spindle with a 5/16" mortise?

I have a 3.5" spindle for a decorative doorknob but the current mortise is not square shaped. My local big box diy doesn't carry a company that just makes a mortise with a square eyelet (I could buy a whole kit and use only the parts I need but, what's the fun in that? Plus why pay extra?) I've seen mortise latch parts for 5/16" online but not 9/32". So can I use the 5/16" kit instead? Does the extra centimeter make a difference?

1/64" difference is irrelevant. You are really trying to confuse imperial with metric...just to throw us off right?

Yea, especially since 1cm is closer to 3/8".

Sorry for the confusion...

What I meant was will the 1/16" difference in spindle and mortise cause malfunction, long-term wear, etc.?

The difference is not 1/64 or 1/16 but rather 1/32". With typical manufacturing tolerances however, it might end up fitting good, or be a bit wobbly. Yes it might wear a little faster, but not too much.
