Casters and MDF -- Which screws do I need? (re: Project Arcade Book)
(1/2) > >>
sofakng:
I'm using the Project Arcade book but it's vague on which screws I need to connect my casters (3 inch depth) to my MDF board (3/4" board).

The book says:
"You'll be using flathead machine screws and nuts to fasten the casters to the cabinet base."

So... I'm sending somebody to Home Depot for me tomorrow but I need to tell them what to get.  

Do I need a certain size "flathead machine screw"?  Do I need a certain size nut?

I'm using size #8 screws for everything else in case that matters...

Do you have the casters already?  If so, send those to HD. Along with the knowledge of that they're going to be attached to 3/4" MDF, that should be all that is needed to get the appropriate size hardware!
bdsjake:
perhaps bolt may have been a better word than screw, if you want to something that connects with a nut and washers.  Just get the biggest size that will fit through the hole in your caster.  I guess a screw would work but I think for casters, taking the weight of the cabinet, a bolt would be better.  Larger than #8 though.  This type of part, doesn't really matter exactly what you use, as long as it ends up being sturdy.
Apollo:
Yup you should really use bolts, I used wood screws but only because I had to. I used 3" wood screws so they shoud have a good chance of staying put and I was screwing in to ply. I would suggest bolts.
ErikRuud:
Basically, a machine screw is a bolt!  

I think the term "Machine Screw" is used for bolts with slotted or phillips heads on them instead of the usual hex head.
