A pan head screw in M1: this guide pulls the row from the standard, adds the assembly numbers an engineer actually uses, and links you straight to a quote.
M1 Dimensional Row (ISO 1207 / ISO 7045 / DIN 7985)
| Size | Pitch (mm) | Head diameter dk (mm) | Head height k (mm) | Cross recess | Reference standard |
|---|---|---|---|---|---|
| M1 | 0.25 | 2.0 | 0.8 | PH0 | ISO 1207 / ISO 7045 / DIN 7985 |
Spanner & Drive for M1 Pan Head Screws
M1 Pan Head Screws use a PH0 cross recess. Match the driver bit to the recess (Phillips PH / Pozi PZ are NOT interchangeable).
Common Applications for M1 Pan Head Screws
M1 Pan Head Screws are commonly specified for electronics, PCB hardware, optical mounts and small-scale machinery.
Installation Tips for M1 Pan Head Screws
- Pozidriv (PZ) drivers ride out of Phillips (PH) recesses and vice versa — confirm the recess marking on the head before assembly.
- For automated assembly, an ACR (Anti-Cam-Out Ribs) or torx-equivalent driver gives noticeably longer bit life than plain PH.
- At M1 the joint is sensitive to over-torque — use a torque-limiting driver and check the head doesn't bury into a softer counterpart.
Mating Parts for M1
For M1, pair with a M1 hex nut (ISO 4032 / DIN 934) and, where used, a M1 flat washer (ISO 7089 / DIN 125A) under the head and under the nut.
