I had a need for some fans/fan parts and these screws are the only things that I've used so far. They were perfect for replacing a 40mm fan on a surveillance system recorder at a customer site. More importantly was that the cool guys at CoolerGuys got my email asking them to turn this order as quickly as possible and they nailed it. Because the pricing was great and I always end up scrambling to find some of these things, I ended up ordering a bunch of additional fans and parts to make sure I was ready next time. These guys delivered ahead of time and everything was correct. Thanks guys!!!
