Hand Tightened Screw

[nur_agus_ipftiuii]

Can anybody tell me how strong our hand can tighten a screw(in Pascal)?

 

Thank you very much and sorry for my English

Hmmm... Im guessing that it depends on the material that the screw is being screwed into.

[d22k]

and the strength of the hand

[AzurePhoenix]

not to mention the type of screw itself

On something like a 1/4"-20 screw, you can generate of order an inch-pound of torque (converts to about 0.12 Nm, I think). Pascal is the wrong unit for expressing a torque.

the screwdriver is a big factor.

I am really sorry for my unclear question.

 

We are not using any screwdriver to tighten it. And it is a small wing screw. About 3 cm wingspan.

 

Thank you very much for your concern

I have tightened one of those pretty tight before. Also, what kind of material are we screwing it into?

[H2SO4]

its a wing screw? Do you mean a wingnut?

[nur_agus_ipftiuii]

All is steel. The screw is steel, and also its bolt.

And, yes. it is wingnut.

 

Thanks all. And sorry for my English

Tighten it until it is snug, then a half-turn more. Tightening it further than that weakens the threads.

Hey !!! I was throwing in some room for the benefit of doubt.
