Gen II reactors:
For 24 well reactors, the ideal torque value is 18 in•lbs. Start with the center bolt first, then go top left, bottom right, bottom left, top right. Go around at least twice until you get to 18 in•lb. Be sure to never tighten 1 bolt fully before engaging the others.
See Gen II Reactor Block Setup.
For 48 and 96 well, the ideal torque values are 20 in•lbs and 18 in•lbs respectively. Start at the top left, then go bottom right, bottom left, top right. Go around at least twice. First time around try to go 10 in•lbs, then the 2nd time around you can go to 20 (for 48) or 18 (for the 96) in•lbs. Again, never tighten 1 bolt fully before engaging the others.
See Gen II Reactor Block Setup.
Gen I reactors:
A torque of 5.3 inch-pounds (0.60 Newton-meters) is recommended. See
Aluminum reaction Block Setup.
Generating a firm seal requires that the torque on each screw be as equal as possible. The user may need to retrace their star pattern several times as tightening one screw will slightly decrease the load on another.
