Universal 6.0 mm T25 Fastener
The Universal 6.0 mm T25 Fastener is designed to secure insulation and single-ply membrane to steel 1.25 to 0.75 mm steel, wood and structural concrete decks. It is available in lengths from 50 to 305 mm.
Features & Benefits
- Heavier shank and thread diameters for maximum strength.
- Deep thread for high pullout resistance.
- Extra sharp drill point for quick installation in new or reroof applications.
Product Use
For steel decks, 20 mm penetration is the minimum allowable. Factory Mutual requires that fasteners penetrate the top flute.
For OSB and plywood, 20 mm penetration through the underside of the board is the minimum allowable. For wood deck (wood beams, wood plank, tongue & groove), 20 mm penetration is the minimum allowable.
Using a screw gun, drive the fastener until a slight depression is seen in the insulation and the plate. On rigid cover boards, care must be taken not to strip the deck. The strength of different roof decks can vary widely and can be adversely affected by moisture and other conditions. Therefore, it is recommended that a fastener pull test be conducted to help evaluate deck condition and fastener suitability. Call OMG to schedule testing.
Note: Care must be taken not to overdrive the fastener. Fastener must be tight enough so that the plate doesn’t turn. For best results, use a variable speed 0 – 2500 RPM screw gun.
