Tevo Tarantula Thumb Nut for Bed Adjustment

So much easier and more precise to turn than the tiny knurled nuts that come with it.

Also works well as the adjuster on the optional Pro Metal Extruder.

A nut presses into the hex and screws onto the existing bolts.
I put a washer between it and the bed mount plate, and the nut you pressed in should be at the bottom to hold it all together.

I remember them being snug so may need a little heat when assembling.
