[psycho_fling]

hi all

looking for a piece of 4mm threaded aluminium round bar around 300mm+ needs to be ali due to weight.

What are you going to use it for? I can't see any kind of threaded ali bar that small being useful in combat robots

[psycho_fling]

It's for my product design course making an electro mechanical reading aid

I know it's not ideal but you could always just thread a bit of normal Ali rod with a die.

[psycho_fling]

that is the other option but trying save a bit of time

Forget treading it with a die. Most ali that size is too soft and will gall.

At least bend in all directions at the same moment.

I could try to thread a titanium rod. But that will cost me a die, at least.

Is weight that much of an issue? I'm assuming you could find a steel threaded rod much easier.

[psycho_fling]

yes weight is the issue ....i want to make it light portable etc....it's proably hard to imagine without a detailed explanation of my product which over the interent is quite hard

thanks guys

How long do you need it?

You could look into M4 Ali Bolts.

[maddox10]

Steel threaded rod M4 300mm long. 21 grams, pricetag, per meter a few £ in any serious DIY shops.

Aluminium threaded rod M4 300mm long 7 grams.

Titanium threaded rod M4 300mm long 12 grams.


How much is that 14 or 9 grams worth?
