Molly Jack 52 Sets Nuts & Bolts Assortment Kit - Round Socket Head Cap Bolts, M4-M8 Insert & Petal Nuts for Hollow Door & Wall

Great to have for my rv tool box

I’m a big believer in do-it-yourself so I tend to work on a variety of projects and repairs for myself and my friends. Most of those projects involve using something like Plexiglas or sheet metal, plywood, and things like that, and these Molly Jack nuts are just the thing when you must attach something where there are no attachment points.The assortment comes in a plastic case and there are a variety of sizes to choose from, this assortment should accommodate almost any kind of material that I’m going to encounter in my projects. The assortment I received appears to be of high quality, with no burrs or any excess oil on them and all the threads appear to be perfect.As a do-it-yourselfer I find that this is a solution to a problem, the more solutions you have for problems, the easier it is to complete, having things like this on hand makes some repairs and projects easier to complete.

For over 50 years, we've been attaching activity "toys" to wheelchair trays for handicapped individuals. Disassembly to insert threaded fasteners (nuts) inside has been time consuming. These shorter fine threaded fasteners make it as simple as carefully drilling through the surface of the item and installing these easily expanded nuts make quick work of making sure the "toys" don't become airborne. The next adventure will be to mount LED light bars in the headliner of our van. Anyplace that might have an unknown (electric wire)hazard behind a surface that you want to make a solid threaded mount is a good place to use these fasteners. Now part of stock in our workshop.

This was the fourth thing I've tried to use on this door to get a hook to hang on the back. When I say fourth thing, I'm including other anchors made specifically for this kind of application. This is the first one to work. That hook is on there and is strong. A couple of gripes, the screws are buttonheads and finding a screw bit that small was a pain. Second, the amount of torque needed to get them to deploy the brace inside the door was more than I expected and it jerked the hook out of alignment, which I couldn't get to go back into straight up and down. This hook isn't going anywhere now though. I've got a couple of other hard-to-hang things that I might try these on too.

The plastic case was really well sealed with stretch wrap then in a cardboard box so it arrived undamaged. And the dividers were still in place. But when I opened the case, I couldn't believe what I was looking at, so I took a picture. It looks like someone took them and just put them in the case randomly. There are 5 sizes, in both bright steel and black. There are 7 compartments. That math doesn't add up. They weren't even sorted by color, or both sizes in the same compartment. Even if I took the time to sort them out myself, how would I do it? I guess both colors, same size, in one compartment, though I'd have to try trial and error to see which combination would work Why bother at all to include a case to keep them organized if they don't start that way? It's the little things sometimes.As far as the nuts go, they work as expected, and are very handy. These are NOT for drywall and hanging things. Those have teeth in them to keep them from spinning in the wall as you tighten them. These are for installation in thin materials (sheet metal, plastic, fiberglass, etc.) A heavier duty version of a rivet nut. Be sure you want to install these where you're putting them, because when they flare out, there's no easy way to remove them, you either need to drill them out or pound them through, and both methods are destructive due to their design and size.

This assortment gives you the ability to mount items in various thicknesses of wall board or other mounting surfaces. All the fasteners are Allen head bolts.There are two finishes, black and plated. These are all steel fasteners and you are able to create a strong mounting point in weaker surfaces. These work well but you must be sure you use the correct fastener depth for the surface you are placing the mount into. You basically drill a hole, insert the anchor and tighten the bolt to expand the anchor. You then remove or loosen the bolt and place whatever you’re trying to mount on the bolt. These work well.

Perfect set of what you need when you need it. I love 'assortments' to get me through until the rest come in. Being a 'tinkerer', I'm always running into special needs that you just don't find at your local big box store. A small electrical box, a blown out thread, and no way to cut a bigger hole in the lid. Boom, insert the jack nut in the box, tighten it and it's threaded and ready to go.Having a good selection to choose from in a small reasonable priced kit is worth the cost every day.

I used these mollys to hang several photos in our new house. Pretty standard installation as is for any molly. Just drill an appropriately sized hole and tap in the molly.Even with the largest size, the M8's, I would not trust them for loads heavier than a couple of pounds. The biggest frame I hung from them were 10"x14". They worked fine.
