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

I got these to clamp against mitered picture frame corners during glue up. I have a number of right angle /squares to use but the accuracy can vary, they can have issues after being dropped , and didnt meet all of my needs. the blocks i ordered have been useful in many projects. They do come covered in machine oil

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

Perfect size for constructing scale model structures. Use with a few small magnets to hold wall sections for gluing.

For the money you cant touch them. First pair was almost a perfect match. 8 months later I bought a second pair with a little better match. A little touch with the surface grinder and I have two set precision matched blocks. Will be buying more.

I put a digital caliper to these and they measured out exactly 3x2x1!!! Surprised the hell out of me for the money....

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

My digital calipers are 11 years old, and have seen a lot of use.

Measured my metric blocks with precision calipers and they are very accurate.

Came wrapped in oil paper, greased up, very greasy actually. Which is great, as Im sure they sat on a ship for quite a while in a container on the salty ocean, on their long journey from China.
