1 mm thick. Used to secure the portafilter baskets into the body. Now also available: a 1.2 mm version.
Works exactly as it should with just the right amount of retention.
The spring was as advertised, fit and the speed of delivery were great.
I've purchased several of these springs, and they just don't hold up. My baskets constantly fall out when I knock my portafilters. They seem to hold for about a week and then lose shape and see you later, basket just falling out. So annoying.
If you change baskets frequently (from Double to Triple for example), you naturally feel the original spring tightness and end up with broken fingernails and bruised finger tips. This spring works very well - it has just the right amount of tension to hold the basket properly, but also is loose enough to allow basket changes easily. Just Buy it - you will not regret your decision.
Two seconds and a perfect fit
Excellent! Great Service!
