Description

Our premium, heavy-duty, self-drilling fasteners are capable of drilling through 1/2″ of steel, drilling and tapping in one step. Stocking brands include Buildex and DeWalt ELCO, assuring quality fastening for demanding applications.

• Unique double fluted point has precise cutting edges to improve drill performance in 1/4” thru 1/2’’ steel
• Engineered for fast drilling and smooth tapping with less effort
• A standard screwgun with a depth sensitive nosepiece should be used to install self-drilling screws. For optimal fastener performance, the screwgun should be a minimum of 6 amps and have an RPM range of 0-2500 (Maximum 1800 RPM is recommended for HD self-drilling fasteners)
• Custom fastener painting is available for all of our self-drilling screws, contact us for painting

Common applications include: metal deck to structural steel or bar joist, clips to structural steel or bar joist, liner panels to structural steel or bar joist, and accessories to structural steel or bar joist.
