Torque Driver: Am I getting too obsessed?

After destroying a few screws over the years by over-tightening them and have a few come loose by under-tightening them I've finally "found" the solution. Here it is from Wiha. Maybe I am getting too obsessed but maybe I won't have any more screw issues. What do you think? Torque is 0,9Nm (7,9in.lbs) and it's a 2mm driver.

Thats pretty neat actually. If im not mistaken on the crk bladehq video tour it shows a tech using a torque driver like that for the screws.
 
Well I read that the torque specs are what I ordered here: 7.9in.lbs, maybe somebody can confirm that?
 
Yes, good idea! I have stripped a few screws in my time too and this would help avoid that.
 
Damn, that's a great tool right there. Think I may get one. I don't blame you for using it, I've stripped my fair share.
 
Sorry, I love tools too, but if you need a torque driver to keep from stripping screw heads and threads... :rolleyes: We are not talking about cylinder heads on a top tier Nascar vehicle, or fasteners on the (now retired) Space Shuttle, or even a serious benchrest rifle...

And therein lies one of the problems: great, you can measure it...but what to set the driver to? I can guarantee CRK has never established any range for this. It may be that all you're going to get out of this is a definitive value for the point at which you can snap fasteners...
 
Motorcycles are one of the few things I've never wrenched - are there fasteners that small on a motorcycle?
 
7.9 inch lbs? No wayyyyy!

Those tolerances are too loose for the mad South African!

The actual torque measurement is 7.8993 inch lbs. Haven't you watched the videos? Chris does everything to the 1/10 thousands. :D
 
When I first read the thread title, I was like Why....??? But I see your point. I have never actually stripped any screws, but have torqued them enough that they lose that perfect hex shape and look more star shaped. NO screws strip as easy as Hinderer's, ( and before anyone starts whining, I have owned 18 xm's in my day and changing a scale one time, since you have to adjust the blade centering by tightening down the scale, your almost always in for stared looking screws ). CRK's used to strip mar more easily than they do now. I know they have since went to making their own now I believe, so this issue has pretty much disappeared.

I personally just snug them up and go. I have never had a CRK screw loosen. I have bougt used sebenzas where the owner put loctite on the screws, talk about a fun evening that was.....lol.
 
A torque wrench can only be of value if the manufacturer specifies a range of torque. I use them for mounting rifle scopes when I have a recommended torque setting from the ring manufacturers.

I don't see the need for knives, so yes, I believe you are over thinking the need.
 
I was chuckling over this and my wife popped in to see what I found so hilarious. I was checking out what one of those drivers goes for on the "Big River"

So it's worth $100+ to "precisely" tighten the screws on a tactical knife. Unh huhhhhhhhhhhhhhhhh

My wife says you have wayyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyy too much money and no wife or girlfriend.

Nuff said.

He's got over $800 in knife sitting right there in the pic. Other makers force you to buy expensive proprietary fastener tools. I say if you've got the $$ and it makes you feel good go for it, just like the knife itself.
 
I like tools myself. If the OP enjoys a special tool to use with his knives, why not? I have my own small "tool set" for disassembly and cleaning of my CRKs, and I enjoy it.
How much $$$ one has or does not have is not an issue here. Neither is a companion relationship.
There are rules concerning personal attacks on this Forum and it sounds to me like we have one in this thread. Unnecessary, uncalled for, and in very poor taste. :thumbdn:
 
Until I read the price I thought it wasn't too bad of an idea but for $100 I think I would rather buy extra screws instead.

Sure looks like a quality tool though. Can't have too many of those. ;)
