Century Radikal - Hawk - 50NX - Predator > Hawk IV: Bolt sizes?

My Posts This: Topic  Forum		I'd like to stock bolts that I can use on my hawk iv.
Is it possible to just buy one length in the various diameters required, and just cut them to length as needed?
If so, what is better, cutting them with a bolt cutter or a dremel?

My Posts This: Topic  Forum		If you do cut bolts, use a dremel with an emory cutoff wheel. Thread a nut on first (below where you will cut). That way if you scrog the threads, the bolt will clean them when you unthread it. Otherwise, you may not be able to get a nut on it if the dremel leaves a burr or something.

BTW, Century uses 3MM bolts for just about everything.

My Posts This: Topic  Forum		Worked like a charm. Bought a bunch of 3x30 shouldered bolts and cut them to various sizes tonight as per instructions.

For a cleaner cut: Chuck up the head of the bolt in a small electric drill
or drill press. Cut with dremel tool while the bolt is turning in the drill and face off the bolt at the same time.

My Posts This: Topic  Forum		Great, thanks for the info, will check them out.

re: chucking... sounds like it would definitely be better but I'm unskilled enough with the fixed target and the dremel I can see things getting ugly real quick with a rotating target

My Posts This: Topic  Forum		Oh yeah - microfasteners - just checked them out - cool.

What does it mean when they have 3 dimensions...

M2.5 x .45 x 3mm

And what is better to use - alloy or stainless steel?

What are the great planes screws made of?

Is it ok to use stronger/stiffer fastners or do they cause wear in what they're attached to?

My Posts This: Topic  Forum		1st number is diameter

2nd number pitch of the threads Units? mm/turn or turns/mm for metric I believe. Its a fairly standard value which increases with diameter

3rd number is length

I have used microfasteners several times. A very good source.

I prefer stainless - strong. The GP nuts a bolts I have bought were all allow ( blend of metals) and definitely easier to break, but lighter. I did a semi qualitative test of this on the 2mm dia allow and stainless from Microfasteners. because many have reported the alloy screws in the ECO 8 tail to fail at 3D rotor speeds.

My Posts This: Topic  Forum		The pitch is in mm/revolution.

For the record, the screws come in a variety of strength
'classes' w/ the strongest being '12.9'. Stainless steel screws
are significantly *less* strong that that.

My Posts This: Topic  Forum		Good to know!

Do know if the threads of the strongest screws are cut or cold pressed? Just Curious.

I would highly urge you NOT to use stainless. Stainless is not as strong (although it is pretty!), and will gall very easily.
