AMI PARTS Universal Oven Knobs - 4 Black Stove Control Knobs & 12 Adapters (4 Long, 8 Short) - Compatible with Most Gas & Electric Ranges & Ovens - Universal Stove Knobs- 90-Day Guarantee

A snug fit going on (though this is probably a "feature" - unlikely to slip off). Otherwise works exactly as intended. Nice that the set comes with a selection of different post lengths (2) and post diameters (2). Only docked 1 star off of value, as I only needed 1 knob but had to buy 4 in this kit.

None of the inserts fit my range knobs

I have an older stand mixer. Knob to raise/lower the tilt head broke. I couldn’t find a replacement part anywhere. The other night it came to me that ‘universal fit’ stove knobs might work. Sure enough the adapters have four hole sizes and one provided just the right size hole for a very tight fit to the metal shaft. And the front part of the knob being larger than the original part is not a problem for my arthritic hands. It’s bright white and the rest of the mixer is grey, but I can live with that.

Worked, we lost the AC know thus worked well.

While reading the description, I noticed an Amazon warning that it was a frequently returned product, as most of the "universal" replacement stove knob choices seem to be. I came up with a backup plan and bought some moldable epoxy putty at the same time as these knobs. None of the adapters fit, so I used the putty to make my own custom inserts that fit my stove. I filled the cavity meant for the insert with the putty, carefully inserted it onto the stove in the position I wanted the finished product to sit. My chosen putty also acts as a glue, so I pulled it off the stove to harden to ensure the knobs are still removable. It's not the most elegant solution in the world, but it'll do until I can replace the stove.

One of my two silver plastic handles finally broke off my Luxe Neo 120 Bidet. After seeing the $7.99 price for one handle before tax and shipping on the Luxe site, I searched on Amazon for knobs and found these. One adapter size was too small and one too large for my D-shape stem. After wasting time and tiring of drilling to remove material from a too small adapter, I took a too large adapter and placed it over the valve stem. I then took three toothpick pieces to create tension and tightness in the open space. I cut them flush with scissors, added some Elmer's glue to secure them inside the adapter and snapped my new knob down on the adapter. When dry, the knob turned fine and tight so I removed the remaining good silver handle and put in another new white knob to match. My bidet is back in action. For your knob needs these are worth giving a try even if you have to tinker a bit. If you need to fill in adapter space get some toothpicks and glue.

The knobs are small

Why did you pick this product vs other products? I thought it would fit. But two fit the stove and two didn't.
