Anyone have a source for bolts like these, I believe they were called plow bolts? these are 80-90 years old but I could reuse them but new would be nice.
Any farm supply or implement dealer should have them.
I would suspect other home improvement or farm stores would have them too.
There's are all to short, I need 2.5 to 4.5 in ones. I went to Tacoma Screw and they have no source for the longer ones. Thanks for you're info. will keep trying.
As already stated, farm supply or tractor dealer. (Farm tractors, not lawn tractors.) The local (private) auto parts down here carries them too, up to 12" long. I bought some a few years ago. But, this is farm country in this area.
The local Case/IH dealer has bolts that are close to what you have.
Bob, I believe the plow bolt to be that which is used to hold the plow share to the tine. From the catalog pictures shown you will see the square shank under the countersunk head to top them turning when being done up. I can understand them not being available in longer lengths because they are used in fastening steel components.
When you want to fasten floor boards to the wooden cross pieces on a wood tray, then the longer bolts are required. I have seen these without the square under the head. As wooden trays have largely been gone for many years, you are unlikely to find them, as opposed to the still current use of plow bolts. These days the usual fixing for flooring to timber joists is a bugle head screw with an allen head hex drive. If you fill the hex void you would have a close replica, but no nut to show on the underside.
Hope this helps.

These are the bolts that hold the wood to the steel bottoms on a Snowmobile ski, and the ski wood is shaped from a 6"x6"X 5 1/2 foot piece of Poplar plank. and all have the carriage bolt square that holds them for tightening. I'm glad that I was able to unscrew them and not needing to cut any. Guess I'll reuse them with new nuts and washers.
Thanks for your help.
I have a box full of 1/4 inch bolts like that,but they are only about 2 inches long.
