1977 M77 220swift Trigger travel screw recall install

I just received the screw from Ruger.
The specs to reinstall the action requires 90 inch pound torque setting on straight slot screws.
My wheeler fat wrench only goes to 50-60 in pounds and the equivalent ft lb is 7.92 .
I don't know if I will fiddle with this if I can't torque it properly. I wonder if Ruger offers torx replacement screws or hexes.

Any work arounds using a regular torque wrench?

Could you tell me where you got the set screw from. I need one for my ruger m77. Thanks Bill

I got mine from Ruger. It's been a few years though.

I tried phoning ruger today no luck getting through to them. What phone number do you guys use?

Go to the ruger site and find the manual for your rifle, the recall info will be right there. I have not installed the replacment because i want to see of Ruger has torx or hex screws for the action instead of staying with the slot heads.
