Loose Bolt

Found an open toolbox on the lower tier of a wooden workbench. The hinge of my knee brace had some play after climbing the concrete ramp from the driveway. Inside a rusted tray sat three steel washers and a loose machine screw. Held the screw against the lower bracket strut to check the gauge. Clean thread. Slid a flat washer into my belt pouch for later. When the road gets rough, gear holds only if you make it hold.#
