Heat-set threaded inserts, ruthex RX series: M2 to M8 and #2-56 to 3/8-16
What hole does a ruthex M3 insert need? · Standard part · basis: ruthex RX series datasheet (d1 insert Ø, d2 tip Ø, L, W min wall, d3 hole Ø); geometry drawn by Xem Studio from those numbers
Exact dimensions. True size, with no printing tolerance added.

- 17 in table
Notes
- Drawn as: lead-in pilot at the tip Ø over the bottom 15 % of the length, two knurl bands at the insert Ø with a relief groove between, thread as a plain bore at the minor diameter (threads not modelled). Knurl texture is not drawn: the insert Ø is the knurl's outside.
- Print the hole at the listed hole Ø, at least the insert length + 1 mm deep for a blind hole (room for displaced plastic), and keep at least W of wall around it. Press the insert in with a soldering iron and insert tip at the plastic's printing temperature until its top is flush.
