Qty 20 M2.5 2.5mm M2.5-0.4 Brass Threaded Heat Set Screw Inserts for 3D
Pack of 20 threaded inserts.
These create much more convenient and professional parts than using "captive
nuts" (where you have to design a slot for a nut, and then place the nut in the
slot and hold it there while affixing a screw). They also can be used in some
situations where captive nuts just don't work.
These are inserted into a hole in the print that is slightly smaller than the
insert, and set in place using a soldering iron to melt the plastic around the
insert. The inserts have a slight taper and small fins that the plastic flows
around, resulting in an extremely strong bond.
Rather than adjust designs around the limitations of 3D printing (supports,
print bed size, etc), divide your parts into separate components that fasten
using these inserts and machine screws. Not only does this give you greater
flexibility when designing a part, but also allows you to re-print only failed
components rather than full assemblies - saving time and money.
These are threaded M4-0.7 with an overall length (OAL) 3.46mm
This is the shorter M2.5 insert - see our other listings if you need the
Outside diameter is 4.4mm (top) and 4.0mm (bottom)
The hole in the plastic product should be slightly smaller to allow plastic to
flow between the vanes of the insert.
