Tikka t3 action screw torque??


Recommended Posts

So recently got my t3 back after being rebarreled and I took the macmillan stock of a bit after to clean it and when I put the screws back in they didn't seen to stop. It gets fairly tight but goes so far that the rear screw goes high enough to affect the bolt. What is the correct torque setting and if I achieve the correct torque before it hits the bolt would it be ok just to slightly loctite it?

No need for loctite.

You might find that it’s not located properly into where it needs to be and not seated into its lug. Also check your using the right screw front / back. This happened to me once, I have no idea why. But stripped again, reseated and had no issues.

Plastic stock rifles with floating lug: 35 inch-lbs

● Plastic stock with floating lug, bedded: 55 inch-lbs

● Plastic stock rifle, unbedded: 40-45 inch-lbs

● Glass stock rifle with unknown fill: 40-45 inch-lbs

● Glass stock rifle with ali chassis: 55-60 inch-lbs

● Wood stock rifle with floating lug: 35 inch-lbs

● Wood stock, bedded or unbedded but without pillars: 40-45 inch-lbs

● Wood stock rifle, pillar bedded: 55-60 inch-lbs

● Laminate stock rifle, bedded or unbedded but without pillars: 40-45 inch-lbs

● Laminate pillar bedded rifle: 55-60 inch-lbs

● Ali chassis/tube rifle: 55-60 inch-lbs

If the McMillan stock hasn’t been pillar bedded then you will be crushing the fill - hence the action screw protruding into the bolt sear guide 

if it has been pillar bedded then it’s been done incorrectly and needs to be altered or the screw cut down to allow unobstructed bolt cycling

 

From reading your post it would appear to be the former and the fix would be to get the stock pillar bedded

 

Onr that’s done 45 -55 inch pounds would be correct torque
