The M1.6 size of Pan Head Screws is dimensioned by ISO 1207 / ISO 7045 / DIN 7985. The tables below give the dimensional row from the standard, the drill and spanner sizes that go with it, and the assembly torque per property class. The technical drawing on this page redraws to the exact values selected.
M1.6 Dimensional Row (ISO 1207 / ISO 7045 / DIN 7985)
| Size | Pitch (mm) | Head diameter dk (mm) | Head height k (mm) | Cross recess | Reference standard |
|---|---|---|---|---|---|
| M1.6 | 0.35 | 3.0 | 1.0 | PH0 | ISO 1207 / ISO 7045 / DIN 7985 |
Spanner & Drive for M1.6 Pan Head Screws
M1.6 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 M1.6 Pan Head Screws
M1.6 Pan Head Screws are commonly specified for electronics, PCB hardware, optical mounts and small-scale machinery.
Installation Tips for M1.6 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 M1.6 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 M1.6
For M1.6, pair with a M1.6 hex nut (ISO 4032 / DIN 934) and, where used, a M1.6 flat washer (ISO 7089 / DIN 125A) under the head and under the nut.
