Perfect angles and dimensions
These are perfect 1-2-3 blocks. I’ve wanted them for a while, and I was so happy to find them as an Amazon Prime Days deal. I use them for building miniatures. All angles are 90 degrees, and the measurements are precise…1″, 2″, and 3″. They weigh enough to keep things flat while glue is drying, and they don’t move around if I’m using them to support two pieces of wood I’m trying to glue. They arrived with a thin coating of oil, wrapped in paper and plastic. I’ve learned this is typical with metal pieces like this, and it was easy to clean the oil off with Simple Green.Two thumbs up.

Didn’t know I needed
They seem pretty perfect to me.I was just introduced to the 1x2x3 block, but it has become handy… Nice as a weight, good square/corner guide, quick 1″, 2″, 3″ ref… I like that some of the holes are threaded.

Used as weights and for Model RR building, I will buy more !!!
OK, so this is not an a traditional machinist use for 1 2 3 blocks, but they are perfect for my needs. I have several sets of drilled 123 block I use to make square wall or as weight laying HO model railroad track. I use these constantly but have never used the drilled holes. I often wished they were a little heavier and a lot less expensive. I have even look at 234 block but I am not paying $50+ a pair. These looked OK and the price was better. Without the drilled holes they are much heavier, almost perfect for my uses. Who knows the true dimensional tolerance and I don’t really care if they develop a little surface rust from handling. I am buying 2 more sets tonight because this are the best I have found for general model railroad building

Great for Woodworkers
1-2-3 blocks could be renamed to gauge blocks for woodworkers; they are accurate in linear and angular dimensions. Also, try to buy them with some threaded holes. Versions come in both metric and Imperial thread sizes. Threaded holes do improve their utility.

Work great for my rifle rest!
I bought these for my Benchrest rifle. The bipod wouldnât elevate my rifle with respect to the rear rest and the rear rest didnât have enough adjustment to suit the bipod.These blocks worked perfectly for my application!
