I've played around with the ubiquitous coil-based thread repair because of the price and their long history, but because of their ease of use and reliability, especially when exposed to non-ideal conditions such as e.g. B. loosening of screws, stripping etc. etc. cannot be compared with time-serts/big-serts. This is the only thread repair that has given me confidence over the past few tightenings. If you're dealing with an easily accessible small, low-torque screw, try a coil insert. Whether you're looking for a series of teardowns, a high torque value, or a mission-critical feature, go ahead and pay by Time-Sert. (Or Big-Sert depending on the situation)
