Great little kit for heat sink mounting

I like to have these in stock

So many electronics assortment kits contain substandard parts.This is a welcome exception: all useful, good quality parts.

I like these better than the old mica and paste. Not messy and easy to handle. I've used these professionally and for my self, and they never failed me.

Nice kit to have on hand for electronics repairs

Handy pack insulators vs cutting one out of whatever you have on hand.

Good little package of everything one will need to safely mount their cans.
