Hi, I´ve just changed the hot end from my K1 MAX and even being an original spare part, I was no able to use the new bolts that came along.
Can anyone tell me the bolt specs used on those hot ends?

Best regards

m2×22 Or m2×10

Non-unicorn will be the longer M2
Unicorn as in the photo I shared will be the shorter M2
