The (M3.5) size of Slotted Set Screws with Cone Point is dimensioned by ISO 7434. 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.
(M3.5) Dimensional Row (ISO 7434)
| Size | dt_max (mm) | n_nom (mm) | n_min (mm) | n_max (mm) | t_nom_min (mm) | t_max (mm) | Length range l (mm) | Reference standard |
|---|---|---|---|---|---|---|---|---|
| (M3.5) | 0.35 | 0.5 | 0.56 | 0.7 | 0.96 | 1.21 | ISO 7434 |
Spanner & Drive for (M3.5) Slotted Set Screws with Cone Point
The hex socket for (M3.5) Slotted Set Screws with Cone Point 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 key gives the most feel when you are judging preload by hand; anything repeated across a batch wants a torque-controlled driver instead.
Installation Tips for (M3.5) Slotted Set Screws with Cone Point
- 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 (M3.5) 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 (M3.5)
For (M3.5), pair with a (M3.5) hex nut (ISO 4032 / DIN 934) and, where used, a (M3.5) flat washer (ISO 7089 / DIN 125A) under the head and under the nut.
