Shars 1 Pair 123 Ultra Precision Blocks (1" x 2" x 3") w/23 holes 303-5502 P]

Accuracy, value

I bought these blocks to use in making set ups on my mill. I wanted to run 5/8" bolts through the non- threaded holes. Those holes all had significant burrs so 2 hours and several dozen sanding drums on my Dremel ... the holes are clean. I expected this for the inexpensive typical Chinesium stuff that it is. Now they are right and will serve me well in my hobby shop.

These are great quality and accurate.

The title says it all: well made and accurate.

I use these to make sure I have square corners on sub-assemblies I make. I also use them as weights to help in the gluing process when clamps don't seem to work at all.I'm a model builder and I need a square joint vertical or horizontally and these are great in helping me make those joints.
