Lependor M4x12 M5x12 M6x12 M6x20 Threaded Knurled Thumbscrew Grip Knobs Thumb Screw for Machinery Latche (M4 M5 M6 Threaded Knurled Thumbscrew)

This multi-pack was the answer for me. If it wasn't one, it would be another, and so it worked out. This was because a mfgr sent a product shy a thumbscrew and was no longer responsive. So I solved it, though I hated having to pay extra for what should have been included. As for some complaints from reviewers that screws are too cheap...well, the application I need is for light use, so if the screw gives out, I have 9 more to fall back on. As for the other 20, I have no idea what to do with them! But I now have a working product.

The is what it is, nothing special but how I wish I checked the length of the screw.. the product should come with longer length to be more useful with projects.

I thought I had a bit of an idea on what size my monitor need since once of the screws was lost. I have a thing about buy an assortment of this sort of thing. I was so glad I did since what I thought I needed (one of the larger sizes) they were huge. So I am glad to have my variety pack for anytime I loose one of these types of screws. I would absolutely buy again.

Just needed one but that one was important. This way I had lots of sizes to choose from and get back to work. Fine for what they are. Thumbscrews.

These are not for heavy duty applications with vibration or excessive forces as the plastic top knobs are small and feel fragile...

I thought this was going to be a really good deal. What I received was not what's shown and described in detail on the listing. You can see from the pictures I uploaded the thumb screws I got do not have a shoulder as depicted in the schematic, all of the thumb caps are the same size no matter what size screw so when you get to the larger M6 thread you still have the same small head as the M4.What these look like are thread in feet for furniture and not machine thumb screws.Not happy at all with these thumb screws...

This was a random assortment of Phillips-head machine screws with cheap plastic knobs molded to the heads which detached with just finger strength. These are trash.

Handy to multiple projects
