Torque Wrench advice please.

[Gez73]

Using a Jobsworth Torque wrench with setting just above 4nm. The bolt seemed very tight, far more than I would probably tighten by hand. The wrench was to my mind not clicking in any discernable way. Watched a video from PX and found no matching alert from my wrench. Is just above 4nm particularly tight for a novice user or have I not tightened enough? Seat stem collar by the way, recommended 4-5nm or 4.5nm, not sure so played it safe. Thanks. Gez

Most people worry about over tightening seat post clamps with a hex key, not realising that 4Nm is a lot tighter than all but the most ham fisted gorillas will exceed. The first time I used a torque wrench I also thought there was something wrong with it as it seemed ages before it clicked on 5Nm.

I would say it is probably ok, but for peace of mind do what I did and find someone else with one to compare values.

I checked a setting on my torque wrench by clamping the business end in a vice and hanging a certain weight a certain distance along the shaft. I'm not sure if this is scientifically sound, but the wrench clicked pretty much bang on when i calculated it should.

That is scientifically sound as long as the vice doesn't budge and you allow for the torque of the wrench itself. I assumed with mine it was the weight of the wrench exerted at a point halfway along its length.

Is it supposed to click?

Mine, which I purchased from Wiggle, doesn't click. When the dialled in torque is reached the head unit just twists slightly along the longitudinal axis of the wrench.

Hi Gez, I've also got a Jobsworth from PX and have just tested it on my set stem collar and it seemed to work OK, although I would say it's not a very definite 'click', I guess it could be easy to miss. I actually notice a small 'kick' feeling in my hand more than hear the click .... perhaps try again but tighten very slowly and wait until you hear the click / feel a kick?

 

[Gez73]

Thanks for the responses, may have expected more of a 'kick' or click than actually occurs. Have tightened tonight and hopefully it is okay. Gez

You'll soon find out, if your saddle gradually gets lower as you ride around it's not tight enough! Simples!

I have that exact same wrench and mine clicks. It is not as loud as my big torque wrenches, but it is certainly audible.

@Milkfloat

That's strange - mine is dead silent. No mention of a click in the instructions either - just mentions the head twisting when the required torque is reached.

Maybe I am going deaf.

I hope mine is not broken!

The video on this page has a very clear click. Far louder than mine makes assuming I am reaching the set torque. Quite different and little worrying to be honest. Might pay the local bike shop a visit with mine and see if they can confirm my one works. Gez

 

[Smokin Joe]

As long as it slips when you reach the correct setting I would not worry. I have a large torque wrench that makes a loud click and a smaller cycle one that hardly clicks at all. It's a bit like Campag and Shimano freewheels, they are just different.

Nope, mine's no where near that loud. I can still hear and feel when it's reached the correct torque though!

Non-clicking mystery solved!

Just been and tried mine. As an aside I hadn't realised both the wrenches linked above were exactly the same just with different names and prices - with Wiggle being far cheaper. I only paid £24 delivered.

I set it to 6Nm for my stem bolts and it does make a noise.

It's more of a soft 'clonk' than a loud 'click' when the little deflection is made at the required torque. Nothing like the noise on the video though.

I've used it maybe half a dozen times now and never noticed the 'clonk' - I am wondering that whilst concentrating for the deflection thing to happen I have switched off my ears.

Whatever, it's a smashing little wrench for not many pennies.
