Freeze your Nuts Off

[Guest]

So has anyone ever tried this ? Has anyone seen it before ?

Another tool in our arsenal for working on our bikes....

Tired of the wasted time and busted knuckles associated with fighting with rusted bolts, nuts and studs?

Loctite® Freeze & Release instantly freezes seized and rusted bolts, nuts, studs down to -45°F (-43°C). This ultra shock-freeze effect causes microscopic cracks in the layer of rust, allowing the penetrating oil to wick directly into the rust by capillary action. The assembly can be easily dismantled after allowing only 1-2 minutes penetration time.

Product Features & Benefits

• Fast The assembly is frozen in less than 10 seconds, and should be ready to dismantle in 1-2 minutes. • Easy No hammer, long pipe, torch or cut-off
wheel is required. • Multi-Purpose Released parts remain lubricated and protected from corrosion.

Put it in your toolbox!

How much and where do I get it?

seems the freeon for car AC would baiscally do the same thing..flip the can upside down and liquid spray the offending nut or bolt..use eye prtection always!!!

[GateKeeper]

not sure where to get it, found the link online at another site....and I tried to use the locate distributor for Canada, but it just crashes

it's now working, put in your postal code and Canada, and it will give you places....

I've used a different brand called "Freeze Off"...used it on some very stubborn header flange bolts on a Caprice...
The stuff worked...and worked well.

And it is more than just cold, they add some penetrating oil that works with the thermal contraction.

I get it at Autozone or any major auto parts store.

I was thinking about a similar idea.
First thing that comes to mind, is that can-air they use for cleaning electronics, which will spray out a cold frost when you spray it upside down, or slightly shake it. Ive been sprayed with Freeon and Can-air...it's painfully cold.

I'm sure we could come up with some more sinister ideas! lol

All the above ideas sound great but will it bring the temp down to the same as what Loctite say's theirs does

down to -45°F (-43°C)

and it also adds this

allowing the penetrating oil to wick directly into the rust by capillary action

-45°F (-43°C).

Well, which is it?

[GateKeeper]

Well, which is it?

They are about equal to each other

-45°F (-43°C).

Nahhh they're totally different, one has a "C"!

[platinum2]

scary when dealing with aluminum though, but concept yea its shrinking the part/stud, c.o.t air gun cartridge will do the same thing more than likely be a lot cheaper, 5bucks for 12 also will work with your tire inflation kits,and bb guns,and paintball guns

There are a number of spray can cooling products on the market which can be quite useful, I use one by

The effect of the cooling spray will be either that of thermal shock which is reported to be useful in breaking corrosion bonds. The other effect is that of contracting the surrounding threads such that the inter-thread clearance may be increased in order to allow movement in much the same manner as does heating.

Either the shock effect of that of contraction/expansion requires relatively rapid change in temperature and by a very significant difference. If the two parts which are engaged are heated relatively slowly, they will increase in temperature at a similar rate so there will not be expansion/contraction stresses created and little loosening will take place.

I question whether a spray can is able to create sufficient rapid cooling of a larger part to be useful but have found the effect to loosen smaller nuts, for example.

Another technique which can be extremely useful by the home hobbist is the use of a "nut cracker" or small sharp chisel applied axially (parallel to the centre line of the fastener) in order to split or expand the nut. It is often very workable to crack the nut across one flat which will free the nut sufficiently that it can be rotated and cracked again. The nut can thereby be removed in pieces from the fastener, allowing the bolt or other fasterner to be withdrawn and repaired.

This can be very useful in salvaging a critical part which may be excessively damaged by galling and abrasion of the threads if the nut is forced to turn. One very useful addition when using this technique is that of some reaction member placed at 180 degrees to the impact of the chisel to absorb impact and so reduce deflection of the fastener.

We typically place something such as a hammer, bar stock backed up by shafting, etc. as a reaction member when splitting exhaust nuts from cylinder head exhaust studs.

Likely most already know but in case someone is not aware.

It is a very useful excercise, for those not professionally trained, to tighten a 6 mm bolt and nut through a piece of steel and try cracking the nut. Money in the bank when one needs to use this technique later to save the day! One needs a small, very sharp chisel and light hammer. I use a chisel which is about 1/4" across the cutting edge for many jobs. A larger one can be narrowed by grinding but some appreciation of the thickness of the cutting must be included.

An air hammer with sharp chisel is a fantastic tool for splitting reluctant nuts but must be backed up sufficiently regarding reaction.
