Phillip,

I don't think Anschutz prescribed a specific torque until the 18 series in 1980. That said, you could start at 4-5Nm. Less torque may work, but given the rifle's age, it's possible (if not likely) a previous owner tightened the bolts enough to compress the wood a little. I would not exceed 5Nm in a wood stock with factory bedding.

Tim,

Thanks for the reply, this might be a dumb question, but what would that be
in inch pounds which my Fat Wrench measures.

Five Newton meters is 44.25 inch pounds.

Action Screw Torque
We have just recently updated our manuals on line as well as on the new CD's which come with the rifle, but for those with older rifles, you can use this information listed here.

The new information:

For correct tightening of the action screws, ANSCHÜTZ recommends the use of a torque wrench, starting at 2.5 Nm ( 22 inch-lbs ) and not to exceed 4.0 Nm ( 35 inch-lbs).

As tim notes, while the 14xx series match 54 rifles had no specific action screw torque recommendation in the manuals, beginning with the 18xx series of 54 match rifles in 1980, Anschutz provided a specific torque recommendations, which were 5 Newton meters (44.25 inch pounds). Aluminum chassis have a recommendation for 6 Nm.

It's possible that Anschutz didn't provide specific torque recommendations in earlier manuals because of the limited availability of suitable torque drivers. Instead, as many Anschutz shooters may remember. Anschutz provided a special allan wrench for tightening the action screws. It had, as Anschutz described it in the manual, "two wavelike elbows" and by using it and the weight of the rifle itself the screws could be appropriately tightened.



Now, with the widespread availability of reliable torque drivers, these allan wrenches are no longer needed and no longer supplied. Shooters can tighten action screws accurately and repeatably to 5 Nm (wood stocks).

Thanks for the reply,
Just talked to Anschutz gunsmith and he recommend between 25-30 in pounds.

This "Anschutz gunsmith" may know something that is overlooked by everyone else, including the manufacturer. You may wish to follow his recommendations instead.

PG,
That's what I'm going to do and if you remember I talked to you about adjusting the trigger pull, well He, the gunsmith told me how to do that also without doing any damage to the trigger, he was very helpful.

As a reminder, action torque will have an impact on the rifle's "tune". Depending on your accuracy requirements, testing at multiple settings (using match grade ammunition) from 15-40 in-lbs is not a bad idea.

Good advice Phil.

5Nm is way too much given that the screws could be dry or lubed and why the same torque on two different size screws?

Some are having good accuracy with the action screws as low as 16 inch/lbs.

Seems to vary rifle to rifle?

And watch out for the trigger guard screw on some models that only needs to be snug on the backing nut.

Eh? Different size screws? Both the bedding bolts on a 1407 (and any other M54 target) are M6 fine pitch. The rear screw is longer, but it's news to me that length makes a difference.

5Nm was recommended with the later rifles that have stacked believe washers under the bolt heads. You may disagree, but that's what Anscgutz recommended.

Wood crush/compression?

I keep reading about this happening, and wondered if anybody has actually seen this.?

The match 54 stock has a steel recoil lug embedded in the stock, I would think if you crush the wood it would be like driving a splitting wedge in a log and would crack the stock anybody ever seen this?
my thought they put that lug there for a reason

While individual gunsmiths and shooters can and do use whatever torque levels they feel are best, they may, however, be unfamiliar with what the manufacturer itself recommends.

It's worth noting that older 14xx series rifles have slotted action screws rather than the hex screws of post-14xx models, and these don't readily lend themselves to high torque levels without the risk of driver slippage. Hex screw heads can be more easily torqued to higher levels without risk and these have been used by Anschutz since the 1800 series was introduced in about 1980.

Over the last forty years, since Anschutz began specifying a torque level first for wood stocks with Belleville washers, and later for both wood and aluminum, the torque levels have been consistent. These were first used in the Anschutz 18xx manual of July 1980. The recommended torque value for wood stocks is 5 Newton meters. For the aluminum stocks the torque level is 6 Nm. These figures are repeated consistently in Anschutz manuals for the 19xx, 20xx, and 54.30 models.

It's worth noting that the Anschutz 20xx series rifles, which have 5mm action screws instead of the usual 6mm screws on all the others in the Match 54 target rifles, also have the same torque recommendation of 5 Nm for wood stocks and 6 Nm for aluminum.

Below is the recommendation in the May 2015 Anschutz manual. It covers the 19xx, 20xx, and 54.30 rifles. (The 20xx use 5mm action screws.) Earlier manuals for the give the same figures for wood stocks, and when non-wood stocks became an option, for the aluminum stocks.
