alpha10 screws, washers and nuts

Postby trunet » July 2nd, 2012, 8:53 am

Hi,

Well, I'm having a hard time trying to find compatible screws, washers and nuts on mcmaster-carr website. Is it possible to you list the exact product number for this general hardware?

As I'm in Brazil I don't want to miss a single screw for an order and pays the expensive shipping again. I can't find the standoffs here, so I'll buy everything from them.

I don't list specific part numbers because everyone may have different requirements for head-style, finish, etc., but the PCB holes are designed for either Imperial #4-40 or Metric M3 machine screws, the required lengths are listed in the parts list. Don't mix Imperial or Metric screws and standoffs -- they won't fit together.

Well,

It appear that mcmaster doesn't like brazilians. I received this email from them.
Hi Wagner,

Due to the complexity of U.S. export regulations, McMaster-Carr accepts international orders only from our established customers. This decision also applies to orders shipping within the United States, because it is based on the final destination of the items. We cannot accept this order or future orders.

Is there nowhere you could buy screws and standoffs in Brazil? Especially in metric sizes?

did you order top-secret NASA hardware? lol

how about digikey/mouser? I've actually ordered (expensive) hex standoffs from them before.

also try amazon, they have hardware vendors and I've bought some cheap fasteners there.

...and if amazon does not ship to brazil, brazil can take its river back and leave 'amazon' high and dry!

I might also suggest you get extra spaces of different hight sizes. round the quantities up and get extra lengths of screws (esp the ones that would hold the lcd display behind a panel).

like you said yourself, you won't want 2 orders! so, if in doubt, get more of this size and that size is close, get that too; those over there might possibly be alternates, get some of them. you'll lose a few of these in the carpets so get extra of those. etc.

;)

that way you are really covered even if you change things around.

Another place to check, which is where I ordered mine, is ebay. I found a seller on there a while back that had all the sizes I needed along with matching screws for much less than mouser.

If looking at amazon they've recently relaunched one of their sites (http://www.amazonsupply.com/s/16413321) which carries this type of stuff.

and of course there is 'poor man standoffs' which is a screw, some space, a nut, a nut, some space, a nut, a nut, ...

and its fully adjustable! one size fits all! ;)

also less weight than stand offs.

over-order the threaded nuts and use them if you need variable or unusual spacing.
