I have an Anschutz Torque Wrench for securing the barrel to the stock, does anyone know off the top of their head what (if there is a recommended) setting the torque wrench should be set at for say an Anschutz 1813 , or is it a matter of preference and just testing different settings / tightnesses to see what produces the best accuracy for the rifle ??? (short of flat out striping it out of course)


Thanks,

The standard factory settings for the Anschutz 1813 and 1913 are 5Nm for each screw. From there you can experiment and adjust in small steps to find the optimum setting.
I have heard that the setting for the alluminum stock is 8Nm.

I recently read an article regarding this question and is as follows:

Most of the time they will shoot best when the action screws are torque to between 4 and 6 Newton Meters (35 to 55 Inch Pounds). You will need to experiment with a number of torques within that range to find the best setting for your rifle. However, 42 in*lbs. Translates to 5 N*M metric, exactly what Anschutz recommends.

Forgive my ignorance - at present I know nothing about rifle stock / action fixing, but I do know a bit about engineering...

In general engineering, torque settings are quoted for CLEAN, DRY threads. If you apply the same torque to a lubricated thread, the compression force achieved will depend on the lubricant's properties. Therefore, achieving consistent results requires dry threads. Whatever the lubricant, the achieved force will be MUCH higher than that achieved with dry threads. BEWARE! Stripped threads are a real risk. It may be, of course that the required torques are well within the threads' capabilities, but comment about consistent force still applies.

Start at 3Nm and go up in 0.5Nm to see what best suits yout rifle/stock, don't go over 8Nm
