Need a screw, where can I get it?

[MikeHunt79]

Managed to snap this today, so I now need a replacement:

I think this type might have "twin grab thread", but no where seems to have these. Tried screwfix, toolstation and B&Q, so perhaps there is somewhere better to get screws like this?

It needs to be the same thread as the corresponding thread already exists...

i'm SURE i saw those when i was in B&Q on saturday...

Well to be fair I've only tried their (useless) website, I'll try going in person later on...

Just looks like a normal screw to me!

Do you have any small time DIY shops close by?

It's not, it has 2 threads, one deeper than the other...

What's it for, any need for it to be identical?

try an online screw store.

It's from a PA speaker (Mackie SRM450), and it has 10 of these screws holding the plastic cabinet together... The screw goes straight into the plastic go the thread has already been made, so I need one with the same thread and length ideally. The cabinet needs to be airtight for it to work properly.

I've only tried a few online stores but I'm not really sure what I'm looking for apart from a screw!

Email them the pic.
and sizes.

Good idea, done.

if it's wood, do what i do, just fill the hole with matchsticks and screw in the closest replacement you find in your toolshed.

Yep I would if it's wood, but this is plastic so I doubt that would work...

The same old drill. Click on a thread expecting to hear about a guy waiting to nail a girl, but instead it's just a bore. I wish I saw it coming

If you can't find an exact match, you can do two things.

1: Use a slightly bigger screw (as in diameter)
2: Fill the hole with epoxy, drill when set, use a similar new screw.

Cheers, I'll give this a go if I can't get an exact replacement...

Is that the total length of the screw or is the broken bit missing?

The total length of screw including the head is around 60mm... Around 55mm headless... The screw snapped at the head.

Try a builders merchant. Hilti woodscrews have that double helix.

Ah, it seems I'm a screw noob... Double helix sounds like the jargon I need! I'll search for double helix and hilti screws and see what comes up...

Failing that....a brothel. Sorry, couldn't resist.

They'll probably be very confused if I mention double helix tho...

Mikehunt needing a screw. Almost worthy of Austin Powers

I would have thought that if you match the length and girth a different thread pattern shouldn't matter. The plastic will be forced to conform to the new profile.

If I can't match the thread and girth then I may have to do this, but if I round out the thread in the plastic I'm screwed!

Try FWB.

Cheers, found them.

Whats the screw head look like?

I work at a screw company so we may have one in stock.

It's like a panhead with an extra wide washer thing which is a part of the head.

Hopefully another piccy should be more clear:

I actually need 2 now as I've managed to decapitate one and bend another!
