Discovered this 3/8 drive, torque limited glow plug socket on ID Parts and bought one.

Whether or not you have a torque wrench, this socket is well worth the money so you don't over torque the glow plugs.
I had just installed new glow plugs and hand guesstimated the torque, which I discovered was grossly under estimated.
After several days of driving, each plug was still seated but barely.
Re-torqued with this socket to an automatic 13 ft lbs.
Not sure how the internals work, but there's no way to over torque.
