Setting Rings

Setting rings are precision length standards used to verify and calibrate micrometers, especially internal micrometers and bore measuring systems. By providing a known reference diameter, they help confirm zero setting and measurement accuracy, reducing drift and ensuring reliable, traceable dimensional inspection.

In this collection you’ll find setting rings from Insize, available in a range of nominal diameters and accuracy grades to match shop-floor checks or laboratory calibration routines. Options support repeatability checks, single-point verification at a target size, and consistent micrometer setup, with attention to dimensional stability and high-quality contact surfaces for dependable results.

They are widely used by machinists, metrology and QC specialists, and calibration labs in precision manufacturing, machining centers, and production inspection environments where tight tolerances, process capability, and documented measurement confidence are required.
