What is a BosScrew? And Why is it Used in Bertolini Church Chairs?

The BosScrew is a technological breakthrough from ITW Shakeproof that creates a screw to boss connection that maintains and tightens instead of loosing over time.  Bertolini saw the benefits of ITW Shakeproof’s BosScrew as a way to solve screws becoming loose after years of use in church chairs.  Instead of the standard screw drilled into a piece of plywood such as the competitors use, the BosScrew tightens over time with regular use.  Gone are the days of flimsy church chairs and having to try to rescrew in parts found on the floor.
