WEN 10423 3 x 2 x 1-Inch Steel-Hardened Precision 123 Blocks, Two Pack

They are both dead on accurate in all directions. They came packed in grease and wrapped in paper. A quick wipe with a rag gets it right off, no issue.

My husband is glad to have

I bought these 1-2-3 blocks to use in scale modeling. Their accuracy is well within model-making specifications. Their weight and shape makes them ideal to hold corners square while cementing and setting-up.

Theyre amazing for making simple mill table setups. I recommend them highly for the hobby shop.

As advertised

Didnt need ultra precision blocks so gambled on these. On my surface plate and using my best gauge these are dead flat. I am surprised and very happy. I have had great luck with WEN products and that is why I bought them.

If you craft you need a boat load of these. They keep surfaces together while gluing. The keep things from rolling up, They are the perfect size. the weight of a heavy book in a smaller size And the holes are spaced so you can put a dowel thru them and create other temporary structures on hang from.

I am a big fan of accuracy. They can be set up to measure from 1-6 inches. For anything in-between, I use a 6 inch digital caliper.

It makes tools square setting so much better. Recommend getting a set.

Square, parallel, and on size (nominal). Bought 2 sets.
