11mm wrenches are old news to those who work on a variety of equipment as using 11mm bolts permits users to use the 7/16" equivalent for convenience or on the opposite side of a fastener combo which has 11mm/7/16 heads on both ends. Someone was thinking which is good as those stands have industrial uses etc too (and should be so marketed!). Other interchanges worth knowing are 13mm to 1/2", 14mm to 9/16", 8mm to 5/16" etc since that gets you more usable tools for a given job from a mixed set or for example a deepwell or impact socket you might have in SAE or metric you can use on the other standard. Casters take a beating so I get the extra lock washer but ideally it would be a star washer. (NASA and aviation dumped split locks because they're nearly worthless. Don't use them on anything critical.) Four locking casters would be an upgrade and it should be understood the slight cost difference matters to manufacturers in volume though not much to buyers. Other cool shop efficiency enhancers to look for (and preferably buy used at auction like I do) include scaffolding. Baker style scaffolds are easy to move and when not in use can be slid over other equipment against the walls of a shop. Rolling stairs are very handy for safely getting to any vehicle height. I combine them for stability using tiedown straps because stair + scaffold = wide and stable. Get an idea of which height range and ease of access saves you time therefore money.
Kind-hearted comments like this are a solid example of why I've never posted to Facebook in my entire life. I just have no desire to interact with people who would normally be polite in person, but are an asshole from behind their keyboard.
