💡 How do you safely anchor a square tube coupling for heavy workshop racking?

These steel joining pieces carry massive tension loads when mounted right on four sided profiles.

- Grease the hex bolts lightly so you can drive them home without cross threading

- Wrench down the hardware in a star pattern so the inner grips clamp the metal evenly

- Snag a handy tape measure to double check that every bay stays perfectly square during tightening

This routine stops wobble early and keeps your project sturdy for years on end.
