Why Drill-Tec™ XHD® #15 Fastener?
Drill-Tec™ XHD® #15 Fasteners have an over-sized heavy shank and thread diameters for enhanced pull-out resistance in steel and aluminum roof decks to secure insulation and single-ply membrane to steel, O.S.B., or aluminum roof decks.
- Deep buttress threads further increase pull-out resistance
- Miniature drill point penetrates decks quickly and contributes to exceptional resistance to back-out as well as pull-out.
