I had a few hours to kill at the store so I made some cedar umbrellas for my patio. I installed these wheels so I can easily move them around the deck tiles. These wheels are a steal. They're solid, twist and turn fairly well, and the shank threads are always well finished. (For you tradesmen they screw perfectly into these inserts: MroMax M6 x 15mm Threaded Insert Nuts Zinc Alloy M6 Hex Head Female Thread 0.59" Length Bronze Tone 20pcs) I highly recommend them and seldom make perfect recommendations.
