Industrial Precision

Engineering Tools for
Design & Analysis

A powerful suite of mechanical calculators for sizing machine elements, analyzing stress loads, and optimizing power transmission systems.

Fasteners & Fits

Ensure assembly compatibility with standardized data for Metric Hex Keys, Socket Head Caps, and Keyways. Built on ISO and ANSI specifications.

Kinematics & Drive

Optimize your drive trains with tools for Planetary Gears, V-Belt lengths, Chain centers, and RPM-to-Linear speed conversions.

Mechanics of Materials

Validate structural integrity before prototyping. Calculate Beam Deflection, Shaft Stress/Torsion, and material properties like Young’s Modulus.

Engineering Disclaimer: These tools are intended for preliminary design and estimation purposes only. All critical load-bearing calculations and final machine designs should be verified by a licensed Professional Engineer (PE) and validated through physical testing.
