Was fixing a tool made in China yesterday and came across a crazy bolt. It had a metric head and standard American 1/4" threads. So it isn't metric nor American, a hybrid. It was threaded into a cast fitting, but if it wasn't, it would have been interesting to see what size nut they would have put on it! Anyone else see this kind of mixture...it's new to me and seems stupid. Pete

It's not that common but I've been seeing odd mixes of standard and metric in bolts for about 7 years now. The first encounter was a 5/8 course thread bolt with a metric stamped 10.9 head. Many of the head sizes are so close together between metric and standard that you can go either way when using a wrench or socket and not know any real difference, expecially if the head is worn a little bit. I routinely run into button head allen screws that take a 5mm allen to fit them but the thread is 1/4-20. I hate metric fasteners with a passion mainly because it requires me to keep two complete tool sets on my truck to be able to work on anything because of the inevitable mixing of standard and metric on machines. I just wish someone would make up their mind and make the ultimate decision and go either all metric or all standard and end all the mixed up crap. The bad thing about that is if they decided on all metric there are still alot of special tools that still aren't available in metric sizes...and that would just make my life that much harder and stretch my tool buying dollar that much more trying to get the ones that were available..... ...

I've never seen 1/4 - 20 grease fittings...I've seen plenty of 1/4 - 28

I've never had trouble finding 1/4-20 threaded grease fittings.

I've seen them used on a lot of equipment. Local John Deere dealer stocks them, as does the Carquest down the street.

The drive shear bolt for a MF-12 baler has a metric shank and an odd fractional head. And uses a metric nut if I recall correctly.

I can't say what size the shank is on those bolts we buy for our 12(woulod guess 3/8 though...), but it's just a 1/2" wrench for the bolt and the nut. Pretty sure the threads are 5/16. Not al that odd ball to me, it just has a thicker shank that reduces down to smaller threads. Standard no, but each manufacturer had a different type of bolt. This way the farmer couldn't get lazy and go with a grade 8 instead of using the right bolts, and end up wrecking something else....
