I’ve come across these great resources in the last couple of weeks:

• Bolt Depot has these handy printable charts for identifying bolts and machine screws. You print out the PDF with page scaling turned “off”, and you can lay your bolt down on the different drawings until you find a match, and it will tell you what the diameter and thread count is. It has already helped me identify a metric bolt on a piece of furniture I needed to replace. Normally, I’ll check the bolt against my nuts to find a match, but I don’t have any metric hardware in the shop. Bolt Depot also has other handy information about nuts and bolts.
• I found these beautiful vintage paint can labels. Turns out the site, called The Dieline, has a whole category of vintage packaging pictures.
• If vintage photographs and snapshots are what you’re after, My Parents were Awesome and Growing up Heroes are two fun sites to peruse.
• And lastly, Jesse Gaffney has her own take on the dearth of recognition for props in our industry.
