Countersunk Wood Screw - Stainless Steel A4

The TTSFS is marine grade A4 stainless steel. Suitable for outdoor use and use in severe weather conditions, the TTSFS has a prismatic countersunk head to ensure a neat finish and type 17 point to prevent timber from splitting upon insertion. It also has a serrated thread which reduces the installtion torque. 80mm or longer variants have an additional milling thread to further reduce installation torque. TTSFS is CE marked to EN14592.
