Dimensional and assembly data for (M3.5) Slotted Headless Screws with Shank to ISO 2342. Includes head size and width across flats, clearance-hole and tapping-drill diameters, tightening torque per property class, and the sizes to step up or down to when the joint requires it.

Spanner & Drive for (M3.5) Slotted Headless Screws with Shank
The hex socket for (M3.5) Slotted Headless Screws with Shank is shown in the spec table — use the matching Allen / hex key (an ISO 2936 hex key set covers the full range). For a one-off, a T-handle key and a calibrated arm will do. For a batch, the only way to get the same preload twice is a torque-controlled driver.
Installation Tips for (M3.5) Slotted Headless Screws with Shank
- 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.
