Seizing, Binding or Galling

**All Threads will seize under high tension. It is a well known and accepted problem especially when using Stainless Steel or other alloys such as aluminium, etc. As pressure builds between the contacting and sliding surfaces protective oxides are broken, possibly wiped off, and interface metal high points shear or lock together. This cumulative clogging-shearing-locking action causes increasing adhesion. In the extreme, galling leads to seizing (the actual freezing together of the threads). If tightening is continued the fastener can be twisted off or it’s threads ripped out.

The frequency of threads seizing can be reduced by using antiseize compounds , but not eliminated. There are also other ways to minimize the occurrence of thread seizing, 

Keep the thread clean and away from dirt and grit, etc.

Tighten the Turnbuckle or Eyebolt slowly. Work them back and forth occasionally to feel if it is tight when loosening.

If the Turnbuckle or Eyebolt feels like it is heating up around the threaded part of the body it is because the metal threads are rubbing against each other under high tension. This can be an early sign that it may seize due to overloading. It may be that you need to go up a size to reduce the overloading. 

**Seizing is not a product fault but is the nature of Stainless Steel material**
