Recently I bought a spare truck oil pan on E-bay (the one with the inspection plate). This one came from some guy in Canada. The inspection plate did not have any nuts to secure it to the pan, and I am having a heck of a time finding some that fit. The threads on the ispection plate are different from the ones I have on my truck now, and I'm baffled. Were the Canadian trucks that much diffrent? Tonight I went to a brand new Lowe's that just opened its doors last week ( you know before the hardware section becomes a disaster area) and I could't find a match. It seems to be 8 mm with a narrow thread, but nothing they had fit. Does anyone have any ideas???

 

Have you tried your local Fastenal store? They carry and can get you almost any and every nut/bolt/fastener ever made.

I would try them.

There is no listing on the Parts CD I have, in fact for some reason for 48/53 flat V8's they don't even show the pan having a clean-out?! They show one on the 6's but no listing for the nuts on them. I would wager they are 5/16"-UNF. They may be buggered from dragging the pan on the floor.

 

Or the wrong ones put on at one time, boogering the the threads...

Good luck.

I just got back from the fastenal store, and I even stumped them. The threads are just fine, as a matter of fact I found one nut in my work bench junk can that fit's perfectly on all the bolts. According to the Fastenol guy, it seems to be a 5/16 nut with a 28 pitch. Normally you see 5/16-24. He didn't have any that fit, but I did find a nuts and bolts place on line that says they carry such a size. Its very weird.

 

Just saw a very heated argument about 5/16-28 fasteners on a vintage motorcycle site. Harley used to use them on knuckleheads.

 

Ross - I think you have that backwards..."knuckleheads used them on Harleys"....

(runnin' and duckin'!!)

Hey, my wife used to have one! Cursed it every day until it went down the road....

Well my Canadian parts book lists it as just a standard 5 1/16 x 24 nut.

 

If you live by a large well-equipped hobby shop that has R/C airplanes, some engines use the 5/16 X 28 for holding the props on (prop nuts).

Just a suggestion...
