Plain Gauges
High-precision plain gauges for accurate dimensional measurement. Our plain gauges are manufactured to the highest standards using premium materials and advanced manufacturing techniques.
What are Plain Gauges?
Plain gauges are precision measuring instruments used to verify the dimensional accuracy of cylindrical features such as holes, shafts, and bores. They are essential tools in manufacturing quality control, providing quick and reliable pass/fail inspection without the need for complex measuring equipment.
At DSN Enterprises, we manufacture a comprehensive range of plain gauges including plug gauges, ring gauges, setting masters, and snap gauges. All our gauges are manufactured using premium grade materials and undergo rigorous quality checks to ensure accuracy and longevity.
