See title. Where can I get such a thing? I bought the a Ritchey TorqKey (4mm) and I'd like to be able to use it on the 5mm bolts on my seatpost clamp.



BTW, the TorqKey is the *****, and it's only $20.

Go to Sears and buy an M5 bit. That bit in the torq key pulls out like any other bit, I assume.

I'd still go with a regular torque wrench, myself. Your mileage may vary.

MIN 

You would think - but that would make it too convenient. I tried it with pliers - no dice.

I was hoping for a bit that would fit over the 4mm hex and turn it into a 5mm hex.

DMF 

"Only" $20! And "only" fits one size of bolt. Such a deal!

MIN 

I am sorry if $20 is a lot of money to you. Commie.

ElJamoquio

Nope, that would only be about .020" per side in wall thickness, and would be a major pain in the ass to make.

I seriously doubt they exist.

MIN 

El - you are probably right. Any suggestions for a real torque wrench?

ElJamoquio

This is the one I have for bike-type-torques. It's by no means the cheapest (try Harbor Freight) or most expensive (Snap-on, etc - I've seen $5K and higher torque wrenches).

That "Ritchey" torque key is just a rebadging of preset torque keys that are being used in the industrial cutting tool industry. Just about eveyone is coming out with them to help keep operators from over torquing the clamp screws on indexable tool holders. Most of them are preset and have the end bonded into the wrench - thus the not being able to pull it out.

I was told this was done to keep operators from putting in other size bits - leading to overtorqueing smaller clamps....

hmm....can't imagine anyone wanting to change to a different size bit......


ANYWAYS....I believe that Ingersoll is marketing one under a brand name "quik-light" that appears to have color coded wrench bases (color coded by torque spec) and replaceable tips. All the literature I have is for Torx-Plus ends.

Check with your local industrial tool distributor. You could probably call MSC, Grainger, McMaster-Carr, etc. and have them track down what you want. My price would be around $7, yours will probably be $40. Smile.

BBB Torquefix with a certified range of 2 - 24mm and allen bits 3,4,5,6,8,10, torx 25.
Removable bits, allows you to use any bit type. Its a reasonable price around USD80 for this type of wrench.

I bought this torque wrench from Amazon:

and then these bits:

if you don't want to go down to your local hardware store.

It should save you some time over finding a funky bit adapter that probably doesn't exist.

MIN 

What does 5N/m (typical for stem torqueing) translate to in the 'Merican system (lb/ft)?

7rider

About 45 inch/pounds

MIN 

Is that 3.75 ft/lbs? [(45/12) ft/lbs] My concern is that automotive torque wrenches will not have the precision necessary for lightweight bike components.

EDIT- 7rider: I just saw your link. That is perfect for bike parts.

Imperial.

DannoXYZ 

Yeah, auto 3/8" torque-wrenches have a range that's too high for most bike-bolts. Although the 33-35 lb*ft needed for the crankarm bolts really should be tightened with an auto torque-wrench. Then 1/4" torque-wrenches in lb*in for everything else. Especially bar-clamp bolts which can easily be overdone.

DMF 

I am sorry that you missed my points, ***, so I will lay them out in small words.

They are:

1) $20 will get you a general-purpose torque wrench.

2) If $20 is change to you, then why ask about an adapter? Just buy a 5mm TorqKey.

MIN 

Do you troll at random or do you predetermine?

1) That was the the point of the second half of this thread. I'm sorry I am not looped in to the world of torque wrenches you apparently are.

2) There is no 5mm TorqKey. It is marketed by Ritchey as being for exclusively for the Ritchey stems - hence 4mm.
