I want to make a heat-resistant putty. I'm using a thermistor

Does it need to be solid at 150C? If not, silicone oil or heat transfer wax would work.
Or if quick response isn't the most important thing ever, you could use spring to press the bead against the metal.

Quick response is important, and yes, it needs to stay solid. The thermistor goes up into the hole from the bottom and if the putty melts, it'll fall out.

Filling the cavity with the thermistor with thermal paste using a thermoplast as plug might work.

tap the hole
bore out center of machine screw just enough for leads
put in thermistor
thread leads through screw
screw in until lightly finger tight (thermistor pressed up against block

Good idea. If the good conductivity/high thermal capacity of the screw is a problem for his application he could turn a screw out of nylon.

Excellent idea, this works perfectly. I like it a lot better than putty.
I added a spring too, which has a double function of pressing the thermistor against the metal and limiting the bend radius of the wires coming out of the screw.
Thank you anon, you're a gentleman and a scholar.
