## What is Mech Edge?

Mech Edge is a practical set of mechanical engineering calculators for the shop, desk, and field. All calculations run locally on your device, with quick, focused tools for:

• Fits: hole, shaft, and tolerance calculations
• Fasteners: bolt, torque, preload, and related checks
• Strength: beam and shaft calculations
• GD&T helpers
• Convert: common engineering unit conversions
• Thermal expansion

Mech Edge is designed for convenient reference without an account or network connection. Use professional judgment and qualified review for safety-critical decisions.

Mech Edge does not provide medical or financial advice. It includes original calculator functionality and does not reproduce copyrighted PE handbook content.
