What’s on the Metric Thread Sizes poster
A 6-row table: Size · Coarse pitch · Stress area.
ISO metric coarse thread. Coarse is the default when no pitch is written.
- M6 — 1.00 mm — 20.1 mm²
- M8 — 1.25 mm — 36.6 mm²
- M10 — 1.50 mm — 58.0 mm²
- M12 — 1.75 mm — 84.3 mm²
- M16 — 2.00 mm — 157 mm²
- M20 — 2.50 mm — 245 mm²
M10×1.25 is a fine pitch: more stress area and better vibration resistance, but less tolerance of damage.

- Who is the Metric Thread Sizes poster for?
- Metric Thread Sizes belongs to the Mechanical Engineering section rather than to a school year, because engineering is not something one grade owns. Anyone learning machine design can pin it up — a beginner, a student mid-course, or someone revising years later.
- When should you use the Metric Thread Sizes poster?
- Any bolt calculation, where the stress area is the number you actually need. A wall chart earns its place by being glanceable from where the work is happening, so Metric Thread Sizes belongs on the wall where that engineering work actually happens, within glancing distance, rather than filed away.
- What other posters go with Metric Thread Sizes?
- Bearing Life, Choosing a Bearing and Belt or Chain? sit alongside Metric Thread Sizes in the Mechanical Engineering section. Printed together they make a wall rather than a single sheet, which is how a reference set actually gets used.Bearing LifeChoosing a BearingBelt or Chain?
- Is the Metric Thread Sizes poster free to download and print?
- Yes. Metric Thread Sizes downloads as a free PDF with no account, no email and no watermark, like everything else in the Mechanical Engineering section. Print as many copies as you like for a home, a classroom, a library or a tutoring group; reselling the file is the only thing the licence rules out.Read the licence
- What size does the Metric Thread Sizes poster print at?
- Metric Thread Sizes is a vector PDF laid out for US Letter, and prints on A4 with Fit to page — the same file, no separate download. Because every mark on it is drawn rather than photographed, it stays sharp enlarged to A3, A2 or A1 at a copy shop. Colour carries emphasis only, so a greyscale print of Metric Thread Sizes loses nothing.Printing guide
