Design notes
Screws into a tapped boss; exits sideways where clearance is short
A threaded cartridge screws into a tapped boss instead of being pressed into a plain bore. That gives a repeatable, removable fit and a positive mechanical retention — useful on equipment where heaters are changed regularly, and on anything that vibrates enough to walk a press-fit cartridge out of its bore.
The right-angle variant takes the leads out of the side of the head rather than the end. On a mold plate with a bolster close behind it, or a manifold in a tight pocket, that is often the difference between an installation that works and one that needs the tool re-machined.
Both variants are offered with integral thermocouples, sealed lead exits for damp or oily environments, and a temperature-controllable build where the control sensor is embedded with the heater.

Questions engineers ask
How tight should a threaded cartridge be done up?
Firm, not forced. The manufacturer's guidance for terminal and mounting hardware is to hold one nut against another when tightening and to avoid excessive force — over-torquing a boss distorts the sheath and can shear the seal at the head. Seat it against the face and stop.
Does a threaded cartridge heat as well as a press-fit one?
It depends on where the heat crosses into the block. A threaded boss makes contact at the thread flanks and the seating face, which is a smaller and less consistent contact area than a full-length interference fit. For maximum heat transfer, a press-fit into a reamed H7 bore wins. Threaded builds are chosen for retention, removability and vibration resistance rather than for conduction.
