Here are some steps you can follow to prevent your stems from coming loose:
Tighten the stems properly: Ensure that you tighten the stems properly before each game. Use a dart tool or a set of pliers to tighten them securely, but avoid over-tightening, as this can cause damage to the threads.
Use O-rings: O-rings are small rubber rings that fit around the base of the stem and create a tighter fit between the stem and the barrel. You can purchase O-rings at any dart supply store or online.
Apply wax or thread lock: Another option is to apply a small amount of wax or thread lock to the threads of the stem before screwing it into the barrel. This helps to prevent the stem from loosening during play.
Check for wear and tear: Over time, stems can become worn or damaged, which can cause them to loosen during play. Check your stems regularly for signs of wear and replace them as needed.
Avoid dropping your darts: Dropping your darts can cause damage to the threads on the stems and barrels, which can make them more likely to come loose during play. Always handle your darts with care and avoid dropping them.
By following these steps, you can prevent your stems from coming loose and ensure a more enjoyable and successful game of darts.
