Spacer / Standoff Mounting Suggestions

Projects General Guidance

Hi,
I'm looking suggestions as to what people use for spacers / standoffs. I'm goint to be using these proto boards mounted in a wooden box for a project. Adafruit Perma-Proto Half-sized Breadboard PCB - 3 Pack! : ID 571 : $12.50 : Adafruit Industries, Unique & fun DIY electronics and kits If I want to keep them off the box floor or mount one on top of the other what spacers do you use? Would you just use long screws inside a plastic tube to mount one on top of another?

Thanks.

Screws and spacers/standoffs are a pretty simple implementation. Here's a part that we use a lot:

--
The QuadRAM shield: add 512 kilobytes of external RAM to your Arduino Mega/Mega2560

Anything that works is good, preferably use isolating tubes ..

Thanks, I guess a Digi-Key order is in order.

Maybe a trip to Lowes hardware instead.
They have all kinds of standoff parts in the specialty hardware section.

I've used bolts and nuts for standoffs.
See this instructable: http://www.instructables.com/id/A-protective-case-for-the-Atmel-AVR-Dragon/step3/Additional-Supplies/
For the instructable I used nylon bolts and nuts from Frys and went all the way through the case
and then used nuts to lift the board off the bottom.

But if you can also use steel bolts and nuts as well or steel nuts and nylon
standoffs or aluminum standoffs.
Lowes has all of this stuff. I've used it on other projects for mounting and isolation.
Just keep in mind that it is easy to cut down the standoffs if
you can't find ones that are exactly the height you need.

I found this M3 nylon kit which was pretty cheap:

I use 6-24 "bolts" and nuts for all of my hardware. Just one size / thread to keep track of. Think about short lengths of wood dowel rods. Inexpensive, easy to cut to length, and insulated . Drill a pilot hole and use the 6-24 to connect.

Back in they day, a friend of mine used to build slot-cars. To mount the chassis into a non-slot-car body (ie pretty much any model car of the right scale) he used to cut sections of the plastic outer part if a Bic yellow ball-point pen. Then he glued a female threaded insert into that, and the screw thru the chassis holes tightened into that.

To this day, dry pens strike me as useful for their outers...
