Easycargo 10 Packs to-3 Heatsink Insulator/Mounting kit (Screw+Washer+Bushing+Insulator), to-3 Heat Sink Insulator Mounting Kit for MOSFET Transistor Voltage Regulator

seems to work fine

These are thick enough to really do the job. I did not use the hardware as I was remounting T 03 on a high end piece and used the old hardware and sockets.

I need MICA insulators but this package consists of silicone insulators. Silicone will not work for me so I return the item to Amazon. For those who can use silicone insulators, this is a good package.

Picture and description says these are TO-3 insulators but what I got were TO-220.

Good product, work as advertised.

Die Glimmerplättchen sind bedingt einsetzbar. Die Größe ist sehr speziell.

Le viti fornite sono troppo corte, chi vende questo articolo è evidente che di elettronica non capisce nulla, questo tipo di MICA è fatta per transistor TO-03, che vanno montati su adeguata aletta di alluminio di solito spessa 3mm! Le viti sono lunghe 5 di cui 2 occupati dal dado, sembra che siate nemici della matematica! Adios

These work well. Thick enough that I don't think the transistor will cut them. Thin enough to cool. Very happy

a quality representation of a silicone gasket as it is supposed to be even included some hardware for mounting to220's.
