06 3721 NZ. pub. 08/14 © ASSY PLUS A2 DECKING CONSTRUCTION SCREW The screw for fastening decking boards. Many types of wood can be processed without pre-drilling thanks to the drilling tip. Pre-drilling is recommended for hardwoods*. Material: A2/304 or A4/316 • Small countersunk head with under-head pockets. The head can be sunk very easily and cleanly with a small diameter. The under-head pockets pick up protruding chips. However, with tropical hardwoods, countersinking of the surface is recommended, as the wood has very short chips. • Grooved shaft. Provides for additional screw strength as austenitic stainlesssteel (A2) cannot be hardened. This virtually eliminates the possibility of the screw tearing off. • Drilling tip. Splitting and tearing of the wood is prevented. • drive. Excellent snug fit of the bit in the screw drive, which allows the screw to be set very easily. Wobbling impacts and sliding of the bit from the screw is prevented when screwing in. * Screwing on of hardwood decking planks: Preliminary tests are required for hardwoods. Pre-drilling of the wood may be necessary depending on the density and moisture level of the wood. It is recommended that the processing device be operated at a low speed. A4/316 Stainless Steel is ideal in coastal areas, marine applications that are subject to salt water or have a risk of high exposure to chlorine. d mm L mm b mm dk mm Drive A2/304 Pack Qty. Art.
