Panel mounting screws and tool

They are M3 with a 8.9mm length (Not including the head).  The head is 7.4mm dia, x 1.4 thick.  With the club panels this gives you 4.4mm of thread length beyond the panel. Make sure the is enough "grab" on your skeleton before ordering.  For injected skeletons this amount seems to work fine. 

Sold in a pack of 50 screws (48 needed 2 to spare), and the tool.
