PiBurn Spare Thumbscrews

Have you lost or worn out of the thumbscrews and need a replacement? Please pick the correct Thumbscrew from the reference picture to determine which one you need. Some used in multiple places.

• M3x12mm Thumbscrews are used in both the Clamp Attachment and back Stopper. Note that yours might be red or blue, but we only have red. They are the same.
• M4x8mm Black Thumbscrews are used for adjustable magnetic feet (two for the back foot and one for each of the front feet)
• M4x12mm Red Thumbscrew is used to lock carriage (horizontal movement)
• M4x16mm holds the clamp arm to the clamp.
• M4x45mm partially threaded Custom Black thumbscrew is used with spring to control clamp arm pressure.
• M4 T-Nut (which might be smaller than in the picture) is used for the back foot and Lock Thumbscrew for the carriage. It is also used for fiber and fixed magnetic feet.
