When repairing or upgrading electrical devices, it may happen that we need a really SMALL screw. That's my problem. I broke the thread in a screw with a diameter of 2.5 mm, length of 3.5 mm, cross-countersunk head. Thread about 0.5mm. Where the hell should I get such a new one?

Ask here It is rare that they don't have something .

Go to an hardware store or something like that, maybe they'll have it there

With this type of surprises, the most helpful is the recovery of clocks or voltmeters from some toys or watches. If you hit something inch, acid is the worst.

With the disassembly of other devices. If someone thinks that he will buy 2mm 2.2 or 2.4 screws in iron, someone is probably not serious.

2.5mm in diameter is not such a small stub. 1mm would be small. Whenever I demolish something, I collect such screws and throw them into the box of ticks I already have two full ones, and more than once I have found some valuable replacement screws there. You can find this type of screws in computer equipment (I have dealt most with DVD laser modules - there are a lot of screws, but they are usually varnished) or in cameras and camcorders.

The nearest warehouse is from the subway. Entire shelves.

Congratulations, because in places where I buy, having three (most often with a countersunk head, which is useless) is a success.

From time to time, you should approach the municipal problem waste collection point and take the old computer, household appliances, and printer from them, and then return them in small amounts. Nipples, bolts, nuts, ... miracles, wreaths otherwise impossible to get, on the order of 2.5 to 4 mm. Cost: flower or beer = depends on the employee (ca).

And I thought that it would be enough to call the shop where he supplies himself and to which I gave the link. And here are so many options.

Finding 2.5mm x 3.5mm Cross-Countersunk Head Screws for Repair & Upgrade of Electrical Devices

Best answers

Where can I buy a 2.5 mm diameter, 3.5 mm long cross-countersunk screw for repairing a small electrical device?

You can usually get this kind of screw from a specialty fastener supplier or by salvaging it from old electronics. One reply recommends srubex.com as a place that rarely lacks uncommon screws [#9260144], and another mentions TME as carrying similar small screws/threads from about 1.6 mm upward [#9261731] If you cannot buy one directly, people suggest taking them from computer equipment, DVD laser modules, cameras, or camcorders, where these small screws are common [#9261403] Another practical source is old devices from municipal e-waste collection points, such as computers, appliances, and printers [#9261560]

Whenever I "demolish" something, I collect such screws and throw them into the box of ticks I already have two full ones, and more than once I have found some valuable "replacement" screws there.

I'm sorry, but in the screwdriver in Szczecin (very often) they only have 4.0 ... sometimes 3.5. I can see the Warsaw city by its location is "focused" and "mine" focuses on mechanics - you can buy even 30.0
That's why I throw away something only after I remove all the threads.

Oh, electronics ... Most of the mechanics are wrong ... (Motronic is about to pounce ...) In TME, where you often look, there is this product from a meter, various threads from 1.6 up ...
I still have supplies from the famous BOMIS, M2, M2.5, 2.6 and various quirks ...

I solve this type of problem with glue, for example Poxipol, I pour the thread carefully, then screw it in, wait until it sets (enough to unscrew it, but not to "pull" behind the screw) and I have a perfectly matched thread.
