For Cheese Head Screws, the M1.6 thread sits in the small-to-medium range of the catalog and is one of the most-asked cheese head screws in this family. The dimensional and assembly data follow.
M1.6 Dimensional Row (ISO 7048 / DIN 7985)
| Size | Pitch (mm) | Head diameter dk (mm) | Head height k (mm) | Cross recess | Reference standard |
|---|---|---|---|---|---|
| M1.6 | 0.35 | 3.0 | 1.6 | PH0 | ISO 7048 / DIN 7985 (cross) / ISO 1207 (slotted) |
Spanner & Drive for M1.6 Cheese Head Screws
M1.6 Cheese 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 Cheese Head Screws
M1.6 Cheese Head Screws are commonly specified for electronics, PCB hardware, optical mounts and small-scale machinery.
Installation Tips for M1.6 Cheese 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.
