Setting Ring & Setting Rings DIN 2250-C | ULTRA Shop

Buy high-precision setting rings according to DIN 2250-C individually, in sets, or via express service as customized special dimensions with ultra-fine steps online.

Setting rings (master rings) according to DIN 2250 Form C form the reliable reference and setting standard for dimensional handheld measuring instruments in testing laboratories, calibration workshops, and industrial quality assurance. They are utilized for the high-precision adjustment and zero-setting of internal measuring instruments such as 2-point bore gauges, 3-point internal micrometers (e.g., Bowers), as well as digital and analog caliper gauges. Manufacturing according to DIN 2250-C guarantees the tightest form and location tolerances – particularly regarding roundness, cylindricity, and the exact dimensional accuracy of the internal diameter – to absolutely minimize systematic measurement deviations in your production control.

Our B2B portfolio covers all requirements of your gauge management seamlessly:

• Special Steel Setting Rings (DIN 2250-C): The time-tested industrial standard made of premium, through-hardened and stabilized gauge steel for maximum wear resistance in the diameter range from Ø 1 mm to 400 mm.
• Tungsten Carbide Setting Rings (DIN 2250-C): The undisputed endurance champions featuring exceptionally long tool life (hardness 90-93 HRA), ideal for high-frequency adjustment and inspection tasks under abrasive environmental conditions from Ø 5 mm to 50 mm.
• Special Dimension Setting Rings (0.001 mm steps): Maximum flexibility for your specific component tolerances. Configure your required intermediate size directly in the online shop to exactly 3 decimal places within the range from Ø 5.001 mm to 260.000 mm.
• Setting Ring Sets in Cases: Systematic compositions of common diameters in protective wooden cases for structured gauge monitoring in tool and mold making.
• Protection Boxes for Master Rings: Custom-fit, impact-resistant protection boxes for material-gentle storage and safe transport of your valuable standards in demanding workshop environments.

Your B2B Advantage for Urgent Requirements: If you require a specific intermediate size for an upcoming initial sample inspection or a production launch, take advantage of our flexible rapid customer service. We manufacture and deliver your customized setting rings up to a diameter of 200 mm via express processing to reliably prevent unplanned delays in your quality assurance. All master rings guarantee seamless, traceable calibration to national standards through optional factory or DAkkS certificates.
