Walther KK500 Torque Values
Hi,
Ive recently purchased an torque wrench and want to play around with torque values on the action bolts.
Any recommendations on what nm the four action bolts should be?
Thanks

Re: Walther KK500 Torque Values
Just in case anybody is searching the topic for the Blacktec model that uses two action screws - 4.5 to 5.0Nm is what Walther recommend to me.
Re: Walther KK500 Torque Values
I will give 3.5nm a try next time im at the range.
Thanks Gerry

Re: Walther KK500 Torque Values
try different torque settings.... it just might change your group size !!
Hammer to shape, file to fit, paint to match...

Re: Walther KK500 Torque Values
Most of my other rifles benefit from playing with the torque, but they all have front and rear action screws. I usually tighten both to factory specs, then loosen the rear screw almost totally...at least for starters.
The Walther only has action screws in about 1 1/2 square inches directly under the barrel tenon in the receiver...none at the rear of the action. I'm not sure playing with the torque will get you anywhere; but I could be wrong.

Re: Walther KK500 Torque Values
I realise this is a bit of a sideline to this thread but since it's related to the action screw area of the receiver I thought I'd ask...(This is just for my own curiosity)
I have the Blacktec stock model that uses the two central action screws to mount it to the stock. The Expert and Anatomic presumably both use the 4 smaller screw holes arranged in a square pattern? Or does either one of them use the same two screws as the Blacktec?
Also, there is a counter bored, tapped hole on the underside of the receiver. There is a matching hole in the Blacktec stock - when I first removed my action from the stock I thought there possibly should be a recoil lug screwed into this hole and mine was missing. I contacted Walther and they told me there shouldn't be anything there on the Blacktec stock. What is this counter bored hole for? Do the Expert or Anatomic models utilise this hole for anything? Recoil lug?
Thanks.
(P.S. - my receiver looks manky in those images, it's actually a coating of Renaissance Wax I was after rubbing on it as a corrosion barrier while it was out of the stock. I'd hate anyone to think I don't look after my gun. Oh the shame!)

Re: Walther KK500 Torque Values
I am a benchrest troglodyte, so I can only speak for the Walther benchrest stock. The attachment hardware includes a steel pillar and taper head hex drive bolt. The pillar goes through the stock and into the recess in the receiver.
