Thank you Royce Im actually waiting for member tropplemops who I guess made some for Joe….
Hello everyone so I’ve been waiting for the m90 screws to be made by Trommelmops-Ingolf and last I heard he was making them after Christmas but I’ve not heard anything so I’m still looking for 4-5 long screws if anyone has any? Thank you

Bill, I looked back at this thread and did another round of searches for M4 "plastic thread" screws. The thing that makes these so hard to find in the correct diameter and thread style is their long length. The closest match I could find was at McMaster, they are 10mm shorter, but you'll still have 60% of the threads available, possibly more if the threadless upper half of the original screws goes into the boss. They also have a slightly different pitch (1.79 vs. the original 1.65mm) but Ingolf used 1.75 and they worked great for Joe. Bag of 10 for $6.50.
Awesome Eric thank you so much. I ordered them and hopefully they work!!! I appreciate it. By the way how is the Maggy D8443 gears coming along?

Actually I was waiting for you to try out the one I sent you, no rush though.
So I got the screws but they were to small compared to original. Not the length but the actual width was to narrow. Oh well hopefully Ingolf can come through for me. Thank you for trying Eric!!!

I would just take a screw to somewhere like screwfix bill and compare screws, i did this a few years ago, they were not the same but did the job perfectly...good luck fella

That's strange because the originals are M4 (4mm) screws, so the ones you purchased should be the same. When I measure mine with a caliper they actually measure a little less, at 3.95mm. I wonder if your plastic is stripped a little.
I can actually see the difference between the 2 screws and these are a bit narrower than the original. I will try and get some pics

Just throwing this out there.
I've had missing screws to several different boxes and I believe at least one was an M90.
I bought screws as close to the originals in length and thread pitch.
I'd heat one with a lighter up and down the threads until it's hot then carefully (but quickly) screw it into the hole so it creates new threads.
Once it's in, the trick is to wait long enough for it to cool slightly but not long enough for the plastic to adhere to the screw.
I always did it with the back off so I can see what I was doing.
Marking the screw for depth is suggested or you could screw through the front face.
I remember putting a dimple in one, it's barely noticeable but after that I would cut the screw point off with a pair of small bolt cutters and mark the depth I wanted.
Just remember which holes use the new screws.

Thank you for the information. I did purchase some screws from Home Depot that actually are really close to oem ones and just had to trim off tip but work great!!!
