I did not test all the points on the board but the several I checked were right on. Only negative thing for me was no easy method of hanging it on the shop wall.

Impressive quality for organizing nuts and bolts. Using it for generations of coffee cans full of hardware .Sturdy with enough space between gauges to check sizes of many nuts and bolts, plus drill bits.Definitely a must have for large scale organization.
