Manual says 2-3 nm, so 17.7 to 26.5 in-lb for stock screws for the HW30 and HW95. The attachment points are different between the 95 and the 30, so on the HW30 (and HW50 also) I just sung up the rear trigger guard screw. The others I tighten at 18 in-lb. No idea on the HW90.

I’ve been using 20 in/lbs on all except the rear trigger guard screw which I use 15 in/lbs, seems to work for me.

Good question because I found that excessive screw torque on the HW95 stock screws can crush the wood of the stock. Also simple dimensional changes in the wood due to humidity changes can cause the screws to get loose after torquing.

Anywhoo..........Here are the stock tightening specs for HW springers per HW in Germany……….
Front stock screws...................2.5Nm (22.1 in/lb)
Large trigger guard screw........5 Nm (44.3 in/lb)
Rear trigger guard screw .........2.5 Nm (22.1 in/lb), however I never use more than 15 in/lbs on my R9/HW95 rear trigger guard screw.

To solve the "wood crushing issue" I posted my HW95 and R9 stock screws with steel piloted screw cups and steel posts..........
