As you can see the thread on that screw is damaged. It still sort of works, as I can tighten it but then have problems when trying to unscrew the handle. Still works, but I'm not sure for how long and as this is quite an important tool for me, I don't want it to stop working when I need it the most, so I would prefer to change it asap.

It is part of the weight I got with my Lencarta boom arm some time ago. Here is a photo of the whole thing

My question is as in title really, where can I buy a screw like this (it has double thread - on the bottom part which is inside of the weight and on the top part, to screw the handle on) or at least what is it called so I can hunt for it myself?

Thanks :)
 
If the threads are the same size can you not remove it and insert the damaged thread into the weight, if i understand your description correctly.

That's a good idea actually. I'm not sure if the threads are exactly the same, but it is worth a try.

Thanks for that :)
 
Sounds like it's more of a stud to me from your description of it; presumably a metric thread. There will probably be someone selling fasteners near where you live so the best thing to do is take it in as a pattern and see if they can find something to match. It's probably a standard metric pitch but you'll need to measure the overall length and outside diameter accurately with a micrometer or vernier gauge. The alternative is to take it into a local engineering workshop as a pattern and get them to make you one from scratch.

You could get a small fine half round file and take the damaged edges off. A Die nut would re-cut the thread, not sure on the size you need but looks to be M10 - M12 (ish).
 
Yep, looks like an M10, B&Q sell them. If you can take it along to compare...

As above, the best option is to carefully file the damage away- with the flat side of a half round needle file.
BTW, you don't really have to use a die nut: a nut that fits would probably rethread it. The hard work is already done.


Try not to drop it again :)

As Andy says, a simple fix could just be to dress the damage to the thread with a fine file...
 
Thanks very much for all the suggestions. I'll be trying to fix it over the next few days (when I get a spare moment).

BTW, I didn't drop it. I don't know when and how it happened. One day it was ok, the next it wasn't (even though it was back in its box overnight).
 
The wife was dusting...

Nah, she wouldn't touch my photography stuff. Neither would my son.

It had to get damaged when screwing/unscrewing. Maybe there was something inside of the handle and when I was tightening it up, it just made a mess out of the thread. Who knows...

I will probably have a look tomorrow.

It looked to me as if it had been dropped- the suspicious dent and scratch on the same side as the damaged thread.

I think that dent was there from new. I'm 100% sure it wasn't dropped
 
Your local steel stockest will have every nut and bolt you could imagine...take it out and take it along ...its a stud ....tighten two nuts on it to pull it out or cut a slot in the top and wind it out as I dont know where you live I cannot find one for you
 
Thanks. I was planning a shoot yesterday, unfortunately I had to cancel it. Not sure if I get a chance before the weekend now, but I plan to reverse it first (as suggested in second post). If that sort it then I'll be a happy chappy. If not, then I'll look at other options :)
 
I'd be inspecting what threads onto that as you may end up replacing/repairing the stud only to get the same result through further use...

Be careful if you reverse it, the casting may be softer than the bolt. I'd try to file it first, just in case ;)
 
As above, the cast (iron?) will be softer than the nut.

Exhausts often use studs at the manifold... If you can wind it out (two nuts locked together as above) then take it to a tyre/exhaust shop. Likelyhood of finding a stud in b&q etc is minimal.

Tap and die set would do it, well the die would. Or you can get a thread file but think they're about £15. Mega usfull, IF you plan on doing it again lol.

Or if your near CM22, drop me a PM and I can sort it at my workshop :)
