Deck-Tite Composite Decking Outdoor Square Drive Screws - Brown

Deck-Tite Composite Decking Outdoor Square Drive Screws - Net Coat Brown Coated

• Deck-Tites unique thread pitch to Core Size Ratio’ gives the perfect balance between ease of insertion and pull-out retention whilst increasing the core sheer strength.
• Tri-Lock Threadform - three flats on the thread means that as the screw is driven in there is less surface contact between the screw and timber, allowing less battery wear, easier insertion and the screw will not work loose as the boards are walked upon
• Reverse Thread at the top of the screw designed to trap loose composite material then drive it back into the hole. Eliminates swarf build-up on the surface of material.
• TS Thread (Exaggerated) - Utilises benefits of both twin and single thread on the same screw. Single Coarse Thread drives in without reaming a hole in the material, enabling a swift effciant fix with high pullout retention. Twin Thread penetrates the dense surface and balances the screw with two points of pickup that start right at the tip of the screw.
• CPT hardened permeated case with through hardening allows the perfect balance between core ductility and surface toughness - with the strength of a high tensile bolt the screw will not snap - no pilot hole required in most applications.
• Spiral point for immeadiate start, pilot drill not generally needed.
• Net-Coat Brown for Outdoor use, developed for the new pressure treated timber and outdoor use.
• Square drive mushroom head, screwdriver insert bit inside every box
• Mushroom round head sites flush, no need to countersink
