Q: What size socket/wrench can I use to tighten the nuts for the u-bolts/u bolts for my outdoor sensor array?

A: 10mm

1. Install each M5 nut in the order above. 1, 2, 3 then 4.
2. Do not tighten with an impact driver. Hand tighten, then a half turn / 180 degrees. No more.
3. If your mounting pole is a soft material (wood, pvc, etc.) you may need to retighten the M5 nuts when you perform your maintenance every 3 months.
