Mitutoyo - 611201-541 Steel Rectangular Gage Block, ASME Grade AS-1, 1.0 Length

all good

Worked well, check the size you want the picture is a bit misleading.

Excellent!

It is a very nice steel block. Just right when you have to prove your ruler can rule. Comes with certification and corrosion resistant wrap. Have serial numbers so if you get more than one you can always tell them apart.

Okay, first this is an essential tool in knowing how accurate my tools are. Also I have a similar guage that costs about 4 times as much. Both are identical in the 1 inch measurment (this one is smaller overall in the other dimensions so easier to use). This is one item any tool kit needs when accuracy is essential (I use it to calibrate my calipers for reloading).

No brainier

This product performed as expected. Quality of manufacture and price were top notch. I would recommend this product to my fellow reloaders.

Checking dial calipers.

Packaging is good enough to use for storage. It’s very accurate in size. I use it to calibrate micrometers, vernier and electronic.
