While assembling my A350 I discovered that one of the screws for the 3d printing bed failed to have the head punched out correctly, so it was impossible to fit a screwdriver into. Does anyone know where I might be able to get a replacement screw? Tried looking online to no avail. Should I contact support?

Thanks.

I only have a v1, but all the bolts on the v1 are metric M4 of various lengths. I bought some more [from amazon](https://www.amazon.com/gp/product/B07DVVKZKZ/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1). The head doesn’t quite match the cylindric head, but they work fine and use the same driver as the OEM bolts.

I can’t remember, are the bed screws M4 countersunk? If so, check out these:

Depending on where you live your local hardware store probably has some little trays/cabinets of misc. screws and repair parts.  
Should be a metric section.
