Here is my adjustment method. I am assuming you are asking about the vertical screw just in front of the trigger blade. This is the weight of pull adjustment.
With the rifle unloaded, cocked, and safety in the off position, adjust the sear engagement screw on the rear of the trigger mechanism so that the lengthwise lap of the sear and bolt stop is about .012". You can see the sear engagement viewing window on the left hand side of the trigger, just forward and above the patent number stamped into the housing. You can actually go with a thinner engagement adjustment by testing for slam fires and trying trigger pull as you go thinner and thinner on the adjustment. Keep it safe and use this procedure only for benchrest work where you will always be on target before you load the chamber!
The next step is to adjust the front trigger adjusting screw (overtravel) by turning it in as far as it will go (don't force it). Then very slowly back out the screw while trying the trigger until the rifle fires. You should have the least overtravel at this point while still allowing the rifle to fire when the trigger is pulled.
The final step is to back out the trigger pull adjusting screw on the bottom of the trigger until it is free of the trigger spring. Put an accurate pull gauge on the rifle and turn in the screw until you have the desired pull weight obtained. My manual says that the pull weight should be under 3lbs, however you and i know that it can go much lower than that. Once again, keep it safe and check for slam fires at each step of the procedure.
When you are finished, you should have a trigger pull that has very little overtravel, minimal sear engagement, and a trigger pull that is possibly as light as 8-16 ounces depending on each individual rifle. I have adjusted several, and many of them are capable of these weights while remaining safe from slamfire. The final slam fire safety testing is critical though. If you are using the rifle for anything other than benchrest, then i would suggest a heavier trigger pull weight as well as more sear engagement, just for safety sake. bob

That is the sear engagement screw. The other (sear) screw on the rear is not an adjustment. bob

The screw in question holds spring tension against the sear itself and keeps the sear properly located in the trigger assembly. The remington 37 exploded drawing of the trigger does not indicate it is an adjustment (does not say it is not either except by not using the word "adjustment" in the drawing as it does with the three adjustment points). Cannot say I have ever put a screwdriver to it on any of my triggers. bob
