1. Intro

There's this little angst that I get when the realization hits that I can't do without an item and I only have one. I've gotten this angst with certain tools such as drawknives, Old Hickory boning knives, Old Hickory watermelon knives, certain Dremel tool bits, etc., etc.
The Carona 7" Folding Pruning Saw is just such an item. I've got two of those.
As great as they are they have a problem. There is a propensity for losing the nut, the bolt or both. I should have learned this lesson when I lost the nut & bolt from the first Carona but I did not.
Because I love this saw so much when the nut and bolt were lost I bought the same saw again.

Guess what?
I lost the nut and bolt again. What a dumby!

Trying to get an inexpensive replacement nut & bolt to match what was original is nigh impossible. The key word is inexpensive.
You can find them on the internet, and they are inexpensive, but the cost of shipping & handling is way out of line.

Here's my solution.

2. Parts ( see photos below )

5/16 - 18 X 1 inch Socket Head Bolt - UPC variable
5/16 Lock Nut, nylon insert - UPC 008236072884

Here are photos showing what is readily available at most good hardware stores and does a really great job.

3. Tools

Allen wrench.
Pliers, vise grip or wrench.
Mallet or hammer.

4. Procedure

Here is what I did a few years ago. With this procedure you will never lose another nut, bolt or both. Indeed, this is what Carona should do.

Place the lock nut over the area where the hex cut-out is. The lock nut is just slightly bigger than the cut-out so it will need to be hammered into place.

The lock nut is placed directly over the cut-out and ready to be tapped into place.

Use a mallet, hammer or something hard ( I had a steel wedge when I did it ) and carefully tap the lock nut into the recess.

Lock nut is in place, deep in the recess.

Now you can insert the bolt from the other side and tighten up just enough to compress the handle and make the blade snug.

If everything fit together like it should you will have a bit of a projection from the head of the bolt on one side and the lock nut on the other.

They both can of course be filed down to be very flat, like shown below, so the saw slides neatly into and out of your back pocket while taking a walk in the woods - like I do.

All done. Nice and neat - never to be lost again.



Feel free to copy the information for your own use.

If you can't find the nut and bolt in your area and want to buy them let me know.
For $3.00 I'll buy them and send them to you. There's an Ace Hardware across the street from me. U.S.A. only !
