Any way to secure tiny screw on reading glasses?

[Square Peg]

I have several of Magnivision Titanium reading glasses. They are by far the best I've tried, and I've tried just about every brand there is.

There is just one little problem. The nose piece and the side pieces are attached to the lenses with tiny bolts with a tiny nut on the inside. Over time (few months), these work loose. If I catch them soon enough, I can tighten them and they will stay put for another few months. If I am too slow, the glasses fall apart.

The ones for the nose piece are much more likely to loosen, probably because they get wiggled more.

I have tried superglue, but it really doesn't hold.

Can anyone recommend a way to secure these nuts? If it is permament, so much the better. I don't know why they don't use rivets. I will never want to loosen these nuts.

go to your FLAPS and ask them which Loctite product they would recommend.

Loctite? I understand they make several different flavors- the stuff for an engine block probably isn't a good idea. As to where to buy it, maybe a hobby shop where they sell RC cars and planes and stuff? They use lots of itty-bitty bolts.

Go back to your eye doctor. They'll tighten up the frames, then use a special pair of pliers to squeeze the screw. The pliers have a cone-shaped protrusion on one jaw that spreads the end of the screw.

You'll get a free cleaning and adjustment, if your doctor is any good. :)

Find someone with a soldering iron and have them solder it, it last forever. Take a small piece of wire that isn't quite big enough for the hole where the screw goes, put it in there and drip solder into the hole. Radio Shack has a low wattage soldering iron that would probably work, but, I bought a 100 watt SI at Hobby Lobby for around $10.00, it's the Hobby Lobby brand, it has enough heat to solder anything.

My old glasses for work are almost totally held together by solder.

use locktight.

The only thing superglue works on is human skin.

FLAPS = Friendly Local Auto Parts Store?

Better than a hardware store?

[Square Peg]

These are $20 reading glasses from the drug store.

Maybe I need a pair of those pliers. Do you know what they are called. A search for "optical pliers" turned up a lot of choices, but not what you describe.

[Square Peg]

I have a soldering iron (if it still works). I can certainly give that a try.

[Square Peg]

Funny. It sure does work on skin. I actually think it has some sort of magnetic attraction and can jump several inches to reach the skin. ;-)

Hi, Dap of Krazy glue won't do?

[Square Peg]

Is Krazy glue different from superglue?

[AZ Nomad]

No. It is worthless brittle tempermental stuff. On a screw, you could count on the micron roughness on the metalic surfaces to be more than it can bridge. Gorilla glue might work, but locktight is designed for exactly this application.

yup, Loctite's been doing this kinda job for sixty years or so?

Careful use of an automatic center punch could stake the ends of the screws as they come out of the nuts expanding them enough to keep them tight. You may be able to find a small automatic center punch at your local Lowe's Depot store. After you obtain one, you may ask yourself "Why did I never get one of these incredibly useful gadgets before now?" I have several different sizes of the things.

A little bit of paint on the threads should do it - primer even better.

Loctite will usually hold a screw.

I would use the blue locktite.It's like a semi permanent bond. Tony
