SplitStop allow you to drive screws into nearly every type of composite decking, regardless of density, without need of a pre-drilling or dimpling function, while eliminating the unsightly mushrooming effect common to many other screws. It is a safe to use with any type of pressure treated framing provides excellent head-setting results, with a smaller, less obtrusive head.
Most manufacturers of composite decking will provide guidance for their product for proper installation.

Often, products that eliminate the need to pre-drill produce a cleaning looking finish with less visible screws.
