1/2 X 13 Threads Per Inch Vintage Trailer Wheel Bolts

Question:

Looking for 1/2-13 wheel bolts can you help? 1/2" diameter, 13 threads per inch, 60 degree taper, 1-3/4" overall length, quanity 5 with left-handed thread, and quanity 5 with right-handed thread, as pictured.

I reviewed all of our trailer wheel bolt inventory and did not have a match for your request. I also contacted our suppliers and was not able to make a match there. The bolts I found were not 13 threads per inch coarse, nor left-handed. I suspect you would have to look for a rare bolt seller who would have this vintage style bolt. Brand new old stock would be the way to go as I would not trust used wheel bolts.

If all else fails, another option is to replace with a modern axle and hub that uses standard bolts. If you get to that point email me back and we can start working on the specs.

I have added a sample axel with hub with brake hubs and without.
