These are some of the numerous nuts and bolts on the swing bridge I posted last weekend. http://365project.org/kathiecb/2nd-fiddle/2014-11-01
Not sure why there are so many. Guess you'd get tired unloosening them all if your goal was to collapse the bridge.
This is sc and yes the bridge is really that colour.
This must have been captured at a lunatic asylum, there are so many NUTS about, lets hope they don't all BOLT or it might SCREW someone's day up. RIVETING capture from one nut to another. FAV for you cheek.
LOL
