More than 350 clear, structured, and practical pages to finally understand — and apply — standards without drowning in incomprehensible technical texts.
Not because of SolidWorks.
Not because of a bad calculation.
Not because of a lack of skills.
But because of a normative detail.
A misinterpreted tolerance.
An incorrect material designation.
A poorly chosen fit.
A forgotten ISO reference.
In industry, standards are not a detail.
They are the boundary between:
❌ amateur and professional
❌ academic project and industrial-ready project
❌ accepted quotation and rejected quotation
This book exists to prevent that.
Because it doesn’t copy standards.
It explains them simply.
With concrete examples.
Real case studies.
Real-world mistakes from industry.
This is not a theoretical collection.
It is a working tool for serious engineers.
✅ Clearly understand the difference between ISO, EN, DIN, and ASME
✅ Know when to use each standard
✅ Master professional technical drawing rules
✅ Finally understand ISO tolerances & GD&T without confusion
✅ Choose the correct shaft/hole fits
✅ Properly select screws, bearings, and standardized components
✅ Avoid common material selection mistakes
✅ Integrate standards from the design phase
✅ Prepare a credible and compliant technical dossier
And most importantly:
👉 Apply standards in real projects, not just in theory.
🔥 Immediate credibility in engineering offices
🔥 Fewer costly mistakes
🔥 Compliant and manufacturable projects
🔥 Better communication with clients and suppliers
🔥 A clear competitive advantage in freelancing or job interviews
Because in industry, those who master standards inspire confidence.
• Mechanical engineering students
• Young engineers who want to avoid real-world mistakes
• Freelancers working internationally
• Mechanical design engineers
• Anyone who wants to move from “I model parts” to “I master engineering design”
My name is Yacouba Marc DEMBELE, mechanical design engineer and freelance consultant for over 3 years.
I have collaborated with clients in more than 22 countries
(United States, France, Canada, Germany, Belgium, Switzerland, Morocco, Mali, Algeria…)
Automotive.
Aerospace.
Medical.
Agriculture.
Industry.
👉 In just two weeks, I generated more than 10,000 MAD (~$1,000) through freelance engineering projects.
And if I was able to work internationally, it’s because my projects complied with standards.
Standards create trust.
🔹 Simplified explanations of ISO, EN, DIN, ASME standards
🔹 Clear tables for fits and tolerances
🔹 Technical drawing examples
🔹 A normative checklist for your projects
🔹 A practical glossary
🔹 Step-by-step practical case studies
⭐⭐⭐⭐⭐
“Finally, a book that explains standards without making them complicated. I understood in a few hours what I never fully grasped at school.”
— Karim, Junior Mechanical Engineer
⭐⭐⭐⭐⭐
“This guide helped me avoid a mistake on a client project. For that alone, it paid for itself.”
— Sofia, Freelance Mechanical Designer
“Practical Guide to Industrial Standards in Mechanical Design” is:
→ A credibility accelerator
→ A shield against costly mistakes
→ A lever to work internationally
→ A solid foundation to become a respected mechanical designer
Every day without mastering standards is:
• an unnecessary risk
• fragile credibility
• a missed opportunity
✅ Ready-to-use standards checklist for your projects
✅ Access to a private mechanical design engineers group
✅ One 15-minute one-on-one session with me to review one of your projects and help you correct your standards-related mistakes
Standards do not limit your creativity.
They protect your project.
They protect your client.
They protect your career.
Do not let a normative detail slow your growth.
And become the engineer people consult…
not the one they correct.
