It’s a “universal dense board fastener” specifically designed to fix and self-countersink in all cementitious boards and into common base materials. The WHX is a self-drilling board screw.

Multiple uses, ideal for fastening cement boards, plywood, and other dense composites and sheet materials.

No. The range uses a single tip/thread style that allows fixing to all common base materials with one screw type.

All cementitious boards, plus plywood and dense composites/sheet materials as specified.

Its single tip/thread design and self-countersinking capability mean it can handle dense sheathing and common base materials without changing screw type.

Anywhere you’re fastening cement boards, plywood, or dense composite sheets to common base materials where a clean, countersunk finish and durability are required.
