INSIZE 4625-20 Brass Feeler Gauge Set 0.05-1.00mm

The INSIZE 4625-20 brass feeler gauge set has 20 leaves spanning a 0.05-1.00mm thickness range, used to check the gap between two closely spaced surfaces. INSIZE makes the leaves from brass rather than steel, so the set can be used around magnetic materials or magnetic fields without being drawn out of position. Accuracy runs from plus-or-minus 4 micrometres on the thinnest 0.05mm leaf up to plus-or-minus 24 micrometres on the 1.00mm leaf. Each leaf is 100mm long, folding into a 195 x 90mm frame.
