Template:FAQ/Questions/multiple boards be secured

How can multiple boards be secured together using screws?
A customer named Laker gave the following account of his success:

Due to the terrific manufacturing tolerances (at least on my boards) the screws essentially self-tapped through the provided holes. I.e., I did not have to use a compilcated arrangement of nuts to secure each board as the screw passed through it. I used a total of three screws placed as follows:

1) I used on 1/4&quot; screw through the hole on the netMMC card located above the default stuart port used for RS-232 connectivity. I did NOT need secure it with a nut after passing the screw through the gumstix.

2) A 1/2&quot; screw on the backside (opposite side of the ports) of the stuart, through the gumstix, exiting adjacent to the MMC card. I placed a washer and nut on this screw to stiffen things slightly, but it wasn't critical.

3) A 1/2&quot; screw on the backside (opposite side of the ports) of the stuart, through the gumstix, exiting along the edge of the netMMC card opposite the power connector.

Advice: either shim, or firmly grip, the cards so the spacing is equal around the edge (none of the cards are flexed) when the screw passes through the next card in line as the spacing will be fixed when it does so.

When time allows, I will post up a URL to some digitial pics of my (primitive) arrangement. Securing the boards, however, was a huge improvement. I can now handle the arrangement with cables connected and it is quite sturdy.
