I use these blocks for set ups on table saws or band saws. They come handing for quick set ups. They are made very well and reasonably priced.

Nice case. Drilled with 5 tapped holes on 2 x 3" face. Screws included. Nice surface finish.Good bargain.

Precision blocks were wrapped in treated paper to prevent rust and blocks, screws & wrench were packaged in a sturdy plastic case. Checking all sides with the micrometer the blocks appear to be dead on accurate. There's a sticky coating on the blocks very much like Cosmoline. I plan to clean the box and coat them with a spray Carnuaba wax, hopefully this will keep them from rusting.

If your plan is to simply use these as they are they will serve their purpose. However if you plan was to bolt them together to make anything more complex then a simple block, good luck. They don’t bolt together. The bolts will only go into the treaded holes, all the other holes are worthless. Not even sure why they drilled them out.
