This is a 4-piece set of precision machinist squares made by Kinex Measuring, a company renowned for producing quality and accurate measuring tools since 1906.

Each square is crafted from two pieces of tool steel, with the bases and blades riveted together using two pins to create a strong and invisible joint. All faces and edges are ground and lapped for straightness and parallelism. Manufactured to strict German DIN 875/1 standards, these squares are guaranteed to be accurate to between 14-18 microns or 0.00055" to 0.0007" (5.5 to seven ten-thousandths of an inch).
The set comes in a foam insert with cutouts for each square and includes a signed inspection certificate.
