A socket set screw in M1.6: this guide pulls the row from the standard, adds the assembly numbers an engineer actually uses, and links you straight to a quote.
M1.6 Dimensional Row (ISO 4026 / ISO 4029 / DIN 913-916)
| Size | Pitch (mm) | Hex socket s (mm) | Engagement depth t min (mm) | Point diameter dp (mm) | End type | Reference standard |
|---|---|---|---|---|---|---|
| M1.6 | 0.35 | 0.7 | 0.7 | 0.8 | Flat point | ISO 4026 / DIN 913-916 |
Spanner & Drive for M1.6 Socket Set Screws
The hex socket for M1.6 Socket Set Screws is shown in the spec table — use the matching Allen / hex key (an ISO 2936 hex key set covers the full range). A T-handle Allen key gives the best feel for setting preload by feel; for production work use a torque-controlled driver.
Common Applications for M1.6 Socket Set Screws
M1.6 Socket Set Screws are commonly specified for electronics, PCB hardware, optical mounts and small-scale machinery.
Installation Tips for M1.6 Socket Set Screws
- Use a quality Allen key fully seated in the socket — partial engagement is the most common cause of stripped sockets at this size.
- For countersunk and button-head variants, chamfer the through-hole to seat the head flush without preloading the head/shank fillet.
- 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.
