I had to move a shower drain and used a 2", 4-Band No-Hub Coupling to tie the P-Trap assembly onto the old drain line. Is this acceptable and, if so, should I tighten the 3/8" clamp screws to a certain torque or is hand-tight adequate? I plan to cover everything visible in the pic with sand to about two inches over the coupling, fill the hole with concrete to floor level (formerly a sunken shower pan) and have a new tile shower installed with traditional mortar bed.

I use a torque wrench. Hand tight can mean many things since we all have different strength levels.

Less torque than you use to remove a stuck pickle jar and more than a twist off beer cap. That is the perfect level.

Or you can buy one of these...

Craps out at roughly 60 lbs.

I played a double header Monday night, drinking an energy drink before the game. I'm still wound up.
I went 3 for 4, but got out on the last at bat of the second game to end the night with men on.
Lot's of things going on though. Lot's.

You have not gone to bed yet? LOL

Reminds me of the first time I had a double expresso after dinner!

That's 60-INCH pounds, so, yes, 5-Ftpd is the spec for fittings 1.5-10" in diameter (80-in/pd for larger pipe).
