Hey everyone I hope you're all well

I was just wondering if anybody could help me with information about screws used to attach bogies.
I've managed to drill a hole that's too big into my SAR 500 class car and I was thinking perhaps I could just get a thicker screw to rectify this problem.
However I don't quite understand how these screws work in terms of size and I want to make sure I get the right ones.
So If anybody could help me with how exactly the sizing of these screws works that would be greatly appreciated.
I assume any good hobby store would stock them.

Thanks for your help,
Nic

See If you can find a fastener supplier near you that sells to the public. Just take the model along with you and they should be able to help . My local fastener supplier has a good range of small nut,bolts and screws that come in handy for my needs . And it's a lot cheaper than buying at a hobby shop .
Hope this helps

What is the material that the floor of the model is made from and what type of screw/bolt is supplied?

It may be possible (if it's a plastic floor) to add a nut to the top/inside and still use the same size bolt. I've never liked the idea of using "screws" to fasten bogies to any of my models. I generally use M2 brass bolts. If the floor of a kit is made of plastic (ABS etc), I will either drill/tap the hole or, preferrably, I will melt the nut into the top side of the floor. This is easy to do if you have a soldering iron....just place the nut where you want it, (make sure it's square!!) and then place the tip of the hot iron on the nut. It will quickly heat the nut and melt it into the floor after a couple of seconds.

If you don't fancy that idea, you can solder the nut to a piece of flat brass/copper about the size of a 5 cent piece (with a hole through the middle) and then glue that to the floor (the extra piece of material gives better adhesion to the floor).

The problem with using a larger screw is that it may not fit through the hole in the bogie frame.

Thanks for the responses, much appreciated

An option is to plug the hole that is too big and start again. I have read various ways to plug the hole but just use any scrap bit of suitable plastic and I have even seen hot glue gun stuff recommended.  Do a bit of trial and see what works for you. It allows you to use the original screw size that you wanted.

An easy way is to drill the mounting hole out and glue in a piece of Evergreen styrene tube. It is easy to then screw the bogie mounting screw into it, and the tube can always be drilled out again and replaced quite easily. The tube is very easy to sand flat .

Yes, works well. Used it on all of my BGB kit underframes. Taught to me by the late Austin Balnaves. Cheers Des

If you ever need bogie screws number 2 size by what ever length you need then go to a fastener place that is local and buy them by the box of 1000 at a time it will be dear at the time by the box but works out cheaper than buying 10 or so in a packet from a hobby shop all the time. I bought $400 dollars worth of various length number 2 screws years back and have not even used up the first packet of 1/4 inch long ones yet and that is correct as the box is marked 2 AB x 1/4 PanXR zinc plated. Mine are branded Staetite and are manufactured by A.N.Cooke manufacturing, 53 Sheehan Roqad,Heidelberg West, Vic 3081 Tel 94550500.

I got mine through a fastener company here in South Australia out Dry Creek way called United Fasteners.

Great to see someone is still building kits, 1000 screws equals 500 vehicles. Big Layout.

M2/ 2-56 screws are good for a lot more than bogies. They fix loads into/ onto wagons, and secure couplers. Essential for a layout, too. As my dad used to say, "there's no substitute for a nut and a bolt"!
