How to torque scope mounts

[Dhindes]

Having issues trying to tighten scope rings correct amounts. Tired a variable torque wrench but to 2 Nm does not seem to be letting off. Really afraid of over tightening. Advice please

Just put a new scope on my .243 about an hour ago.
Wheeler torque wrench, no issues.

They reckon holding the short arm of the Allen key and tightening as much as possibly with thumb/forefinger is roughly correct force...not holding the long arm and using all bogey pickers to wrench it tight

Wheeler FAT wrench

Just bought digital one from csc. Half the price of the Wheeler. I am sure it is a good tool but at £80 for something we only use occasionally there are other options that do the job just as well

I use Wera torque wrenches and bits - super kit and has never let me down. I've used it to mount all my scopes. Other brands are available!

Plus one on the Wera kit, had mine for three years now, can’t fault it

Wiha, Borka or Fix-it-stiks will help. The Wheeler FAT wrench can be a bit of a crap shoot as to accuracy.

Scope ring torque settings should be taken as an estimate. The scope itself plays into it, as does the number of screws and the size of the screws. Some are 50 in/lbs (ARC M-10's), some are 25 in/lbs, and some are 15 in/lbs. It really all depends on the many variables.

25in/lbs has been a pretty common torque setting for traditional rings, with the bases being torqued 50 in/lbs to the rail.

Also, where you put the rings matters. Some erectors do not respond well to having the tube constricted in certain positions along the tube.

I like that approach. Do you know if this force has been measured with a torque wrench?

Done it for years never had a problem.

No idea off hand but I heard it years back, tried it and didn't have any issues, I do have torque wrenches now though. May be letting one go if your interested?

No worries, I'll take your word for it!

This is what I do.

Yep - hold short leg to tighten, long leg to loosen. Simples.

I use this. Sealey STS104 Torque Screwdriver Digital 0-20Nm 1/4inHex Drive Happy with it so far

 

[The Optimist]

These work extremely well.

And I can't recommend this set highly enough!

Of course,its on the SD,known as the TALK wrench!
