Threaded fasteners have been around for a long time, and are well proven in history.
In the past few weeks we have had several faluires with the flip caps.
The old screw in caps on Stihls would occasionally viberate loose unless tightend with a scwrench. This caused the screw slot in the middle to wear through. But at least they did not fail suddenly and completly.
Imo Sthil should have copied Husky and built in a better seal for the caps and left them with no moving parts.
The last faillure happened early last week while we where taking down a large crane tree. The flip cap on the climber's 361 came apart. The outside part with the flip came off and left the black part in the hole, but the gas was pouring out. By the time it was repaired and back in service, we could have bought a new 361 for what it cost to have a 90 ton crane with crew, and two tree company's sit and wait for the climber to get his saw back.
