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

So flexible, can use it to set up any fixture or tool. Cant imagine not having a set.

very nice grind and chamfered holes, threads in block except bolt threads great. I would definitely buy more.

I am using these for weight when gluing paper crafts. The oil was going to be a problem since I am working with paper. I washed them really well so no oil would absorb into the paper and they rusted. I cleaned the oil off so I can still use them but maybe not the best product for paper crafts.

I checked it with a machinist T and this block is square. Thickness is very close to 1-2-3 inches. Holes are inot lined up, but I bought this knowing this so price seems fair.

Perfect

Great product. Sucked opening them as they are wrapped in a oil paper and are really greasy. Im sure to prevent them from rusting as they are not coated with a clear coat . They are accurate and have many uses

The 1-2-3 blocks were good - I was getting 1.0001 measure on the 1 face.

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

Being as I use these as much for model building as for machining, 5 decimal place accuracy wasnt a concern. They seem well made and finished and do exactly what I bought them for.
