• View upper and lower deviations, tolerance values, and resulting limit dimensions.
• Calculate complete hole-basis and shaft-basis fits.
• Determine maximum and minimum clearance or interference.
• Identify clearance, transition, and interference fits.
• Explore commonly used fit recommendations and their typical applications.
• Quickly revisit the 10 most recent tolerance lookups and the 10 most recent fit calculations.
• Expand history entries to review complete calculation details.
• Perform core calculations directly on your device.

DESIGNED FOR

• Mechanical engineers
• Manufacturing and machining professionals
• Technical students and instructors
• Designers working with shafts, holes, and precision assemblies
