Review on Enhance Your Gaming Experience with Mekela 5 Pairs of Replacement Thumbsticks for PS4 Controllers - Includes Cross Screwdriver! by Leslie Mayo

This is the best option for those thinking of thumb fasteners. I was about to throw my controller away because the rubber sticks were peeling off. So I disassembled it and installed these. Just be careful not to damage any of the internal connectors when disassembling your controller. I can not distinguish this joystick from the original. It's worth it.
