The advantages:

Installation:
The fastener has been designed for installation using a pre-heating process.
Care must be exercised to ensure that the fastener softens but does not melt
the plastic.This will avoid any tendency to generate unsightly flash around
the top of the insert and ensure optimum performance.Excessive pressure
should be avoided since this may result in the insert being forced into the
hole without allowing the plastic to soften and flow around the surface
profile.
