Hi All,
I am desperately needing a blade mounting bolt (preferably 2), for the Jinma belly mower/ finish mower. It is a L hand thread Metrric. Having problems finding a dealer who sells the Jinma mowers. I used to be a dealer and sold these mowers. I tried to contact my old vendor in china but they replied “we cannot supply this part right now”!? I have searched the web for US bolt suppliers and can't seem to find anyone who has what I need. Maybe someone here knows of a large US supplier who has L H thred Metric bolts? I'd rather call a US Jinma dealer for the part anyway. thanks, Glenn

You have apparently hit on the one hardware item that no one in the entire world of commerce seems to stock. My industrial suppliers list a wide variety of metric nuts in LH thread of all sizes and types, but not one single LH thread metric bolt. It seems bizarre that they sell all those nuts but no bolts to put them on – are there nut collectors out there who have no need of bolts but who buy nuts? Very strange!
I got curious and did some searching through the Thomas Register for this and found a number of companies that will make them for you. Of course they're gong to want you to buy a hundred thousand of them…
I would suggest you call the customer sales and service people at both McMaster-Carr and MSC Industrial Supply and ask them for help. They offer the nuts, after all. Who do they suggest you get your matching bolts from?
If they can't help you, contact a machine shop and have them make you one or two. They'll be pretty expensive but less expensive than a new belly mower, I'd think. An alternate possibility is removing the blade spindles and having them bored and tapped for either LH thread SAE bolts (which are available) or RH thread and using some Loctite to keep the bolts form loosening. The only reason they're LH thread is to prevent the rotation of the shaft from loosening the blots in use and Loctite would accomplish that just fine.
If you have a buddy with a lathe, you might talk him into making you a couple special LH bolts just for the challenge.

1st, Thank you Rick! I appreciate the time and helping info. I did think about tapping the spindle for SAE but it seemed like a last resort. I now see that Tommy has the bolts at Affordable. Last time I checked for these bolts was a couple of years ago (no one had them), I folded up AGPRO Tractors and moved to FL. Now I'm back in Missouri and have three acres of grass. The belly mower will sure beat the 42″ Craftsman mower! I'll call Tommy tomorrow. I've done parts biz with him before. AWESOME! I'll be cutting high grass in No Time Now! LOl.
