Why is the handle screw for the PEF, PXF, PAF, PCF, PHF cirucit breaker made of nylon? Can a metal screw be used instead?

The nylon serves as an insulator, and must not be replaced with a metal screw. Doing so would potentially expose personnel to energized parts. Part # 22999-39701 for the nylon screw only may be ordered from the Cedar Rapids plant.
