Something I need to torque about..

[Flat Lander]

Why do bike part manufactures quote "dry" torqued figures when they also recommend lub'in the threads as well? dont get it

 

[Flat Lander]

just had word back from thomson and it says

"Grease on threads only, no use of anti-seize."

so it looks like their torque values require the screws to greased prior to torqueing. Makes sence.

U sure about that?

Roberto you forgot to mention the coefficient of friction of different anti seizes and the effect that has on torque values :roll:

I didnt :

I have noticed in 'some' manuals it not only says in text if the setting is wet or dry but also (if wet) the spec of the oil / grease / thread lock etc that should be used

Some specs for thread lock make reference to the effect on torque

I will get my coat ...

Yeh,i did email thomson and quoted their reply.

They suggest some grease prior to torquing. For an anal us engineerinf firm i was surprised they did not specify the grade of grease.

Anyway torque is quite a crud way of delivering the correct strain to a fastener. But cheap, and bettering than flogging the life out of it.

I already have a torque wrench built into my hand and wrist. Its called 'feel'...

Just ask my missus
