At my club today trying out a new scope on a rifle, as I was fitting it a club member said... "Hey, you want to use my torque screwdriver"

I said yeah sure, he set it to 18 ft-lb and I clamped my scope rings up until it clicked.

It was quite nifty, and me being me, I now want one.

They can be had on eBay and Amazon etc. for around £15.

Is it £15 well spent?

Only if it’s accurate.🤔
 
I just bought one for just over £20 from Amazon. I’ve never bothered before, but just bought a new scope, and didn’t want to over tighten the bolts.
Well worth it I’d say, should have bought one long before

Probably 18 in-lbs?
 
Should defrost be in-lb not ft-lb, normally if you use an Allen key and tighten using the short arm then as tight as you get with one finger and thumb is about right. If you use the long arm then you can multiply the torque 2 - 3 times…
 
The way I look at it, buy a decent scope and tie in the cost of a decent torque wrench, mess the pressure up and you get a costly bit of crimp damage, apart from my PCP i have blaser mounts and each one is set as per the mounts bolts and scope , i check each scope to fix in the mount I have hawke scopes on my 177 PCP, 22 Rimmy, 22 WMR 22 hornet .204 , and Swaro, Zeiss and S&B on the other rifles, all set to respective pressure as per blaser requirements from memory
Blaser rings
1.7 - 2.8 nm
Blaser mounts
2.3 - 5 nm
Cheers

I've got a Wiha torque screwdriver, which was expensive, but accurate and is calibarated from the factory. I have to admit I'm a bit of a tool tart and I'm pretty fussy about my tools. I do electronics and computer repair etc. so it's used in my workshop anyway.

Amazon are now doing it on 5 months interest free, so if you fancy treatiing yourself? ;) Of course if you're only going to use it occasionally it's probably overkill, but hey ho... ;)

I find 18 in/lbs for scope rings & 35 in/lbs for the dovetail/picatinny rail is more than enough for PCP's.

The torque screw drivers found on amazon & ebay are usually in/lbs & max out at around 70in/lbs or 8Nm

For ft/lbs you would need at least a torque wrench similar in size thats found in a socket set.
