Impact Trigger Hanger Bracket Torque

[Cardboard Assassin]

Does anyone know if there is a magic number for what value to two small screws that hold the trigger hanger in an Impact 737R should be torqued to?

If there is they sure made it hard to find - I've searched the Impact site and trawled the web (including here).

Maybe there isn't a magic value and I just have to wing it?

Wing it on the finger tight side of torque. I don’t think they can even physically come out once the action is torqued into a stock or chassis.

Thanks Cynical.

I’m an OCD type and semi winged it in the end, didn’t have value given to me but 15 inch lbs felt “right”

I've also trawled this site, and came up with 12 in/lbs.

The screws can absolutely back out, and have done it for me. The danger is that if it backs out enough, and the sear is no longer engaged, the firing pin will drop on bolt close.

I use blue loctite on my trigger hanger screws for all my Impact actions now.

Good to know, what chassis or stock?

MDT ACC, but really applicable to any chassis/stock.

I also blue loctite the screws

With this information in mind I will apply blue Loctite and torque to 12 inch pounds.

Thanks all.

I just asked Impact that question and, as stated, Tate said 12in/lbs.

Great info, did they mention if blue loctite was something they'd recommend?

 

[greentick]

No. But I didn't ask either...

This is an old thread but I just wanted to confirm that the trigger hanger screws will back out. It happened to me in a match today. Fortunately it only lead to light hits. Blue loctite and retorqued. Everything now seems fine.
