The shelf in tbe closet of our 5th wheel fell down while traveling. After inspection it was noticed that the shelf support was only wood screwed to the closet wall paneling in 3 places. I patched the holes and offset new holes with these wall anchors. They were easy to install and are quite secure to the thin RV wall paneling. I got a pack of different sized M4 cabinet pull know screws and used those to hang the shelf bracket back up. Secured tightly and my shelf works great now!

These are the perfect items with the best tool. Better than the rivet that broke.

NOT “NUTSERTS” NOT "RIVNUTS" ACTUALLY “MOLLY JACK NUTS”Bargain Price for Superior High Quality Molly Jack Nuts & bolts assortmentThese ARE NOT “Nutserts” as falsely claimed in the headline. These are “Molly Jack Nuts”. A Nutsert, or Rivnut, is a full cylinder such that the whole cylinder folds up against the inside underside of the panel. A Molly Jack Nut has 4 thin petals that fold up against the inside underside of the panel. I took off one Star Rating Point for the false nomenclature use of the wrong item name.These are superior quality Molly Jack Nuts with matching bolts. All the pieces were flawless so the manufacturer must have high Quality Control inspection standards. I used 4 right away to set a bezel in a sheet metal panel and they worked perfectly folding tightly against the backside of the panel. Molly Jack Nuts are easier to use than “Nutserts” and are better for most applications. You do not need a special tool to install these, but if you have a lot of them to install I recommend that you get the installation tool.

Require a little learning curve but they replaced the torn out license plate bolts. Work well for repair.

Although the installation tool is not 💯 necessary, it really makes the job easier. Truly a ... 🫰.I purchased the kit to repair failing attachment of the headliner furring strips in an RV ceiling. The strips were just screwed to thin non-wood paneling. Over time the weight, thanks to gravity, along with vibration, caused the furring strips to loosen. Opinion... jack nuts really ought to have used at the factory. Stainless steel was chosen just for added/forever security. The 5M are a bit overkill, 4M would have been more than adequate. All things being equal, I would have chosen it. However the 5M was selected being more readily available.

These did a good job for M8 bolts. The issue was that it required a rivet nut tool because unlike other jack nuts, this has no gripping ability. This made them hard to use, and they still spin with silicon etc applied. If they push against a corner, they may be okay.Just beware how you need to use them. I was not able to tighten the bolts as much as was needed. Still.kept them in place and applied silicon adhesive in the end.

After an exhaustive search for an M-5 jack nut installation tool, my journey led me to a series of dead ends. From the perplexed expressions at Harbor Freight in St. George, Utah, to the unyielding shelves of Ace and Walmart, and even the specialized yet unhelpful body and welding shops, the tool remained elusive.But persistence paid off when I finally found it. This tool is a gem – it promises fast installation and delivers on that promise. However, a word to the wise: caution is key when working with plastic. The accompanying drill can be a bit too enthusiastic, leading to over-tightening and the potential mishap of the jack nut falling out.Despite this minor caveat, the tool’s efficiency and effectiveness can’t be overstated. For anyone in need of this specific tool, I wholeheartedly recommend making this purchase. It’s a decision you won’t regret.

I used these pedal nuts to mount a kayak tie-town cleat in a position where I could not access the interior to fasten a nut. With a thin plastic wall thickness, screws were not an option, especially with potential load on my tie-down straps.I measured the widest diameter of the pedal nut and chose a drill but that was ~.002 smaller. The pedal nut easily pressed through the hole and the included tool made for an efficient installation. It would have been nice to have the M4 bolts included but that's not a real concern as I specifically procured bolts with a countersink bevel that matched my cleat.
