Assembled a new a new steel shed in the backyard over the last week. Made in China and a bit of nightmare to assemble. I replaced a lot of self tapping screws with pop rivets. To make life easier I bought an adaptor for my cordless drill-driver for clinching the pop rivets. It cost less than 15$ and works a treat, very fast and easy and unlike normal rivet pliers dosen't snag your hands (ouch !) when you close the rivet.
It has a hex drive but not the normal 1/4" so works best with a 3 jaw chuck.
