6.0 mm diameter cold forged self-drilling self-tapping screw fasteners, with an internal SQ3 square drive and buttress thread form. Designed to provide optimal performance in thin gauge metal or timber decking, and suitable for use with a range of pressure plates and washers.

A Silver SFSintec DUROCOAT coating provides corrosion in excess of the requirements of Clause 2, UEAtc directive 'Supplementary Guide for the Assessment of Mechanically Fastened Waterproofing' and Factory Mutual FM 4470.

Installation:

SBF-SQ3 fasteners should be installed with the appropriate installation tool, to avoid damage to the deck and to ensure correct setting.

Pressure plate/ Washer:

• DTL-70 x 70: 70 mm square galvanized steel washer with rounded corners for attaching thermal insulation. The washer's flat surface makes it ideal for attaching insulation boards beneath adhered membranes as it reduces the 'ghosting' associated with many insulation washers. Requires one fastener assembly per washer.

• Sarnabar 15/6: 3 mm thick linear bar used to attach the Sarnafil membrane in Sarnabar systems. Roll formed from steel strips galvanized to EN 10142-FeP03GZ275N, Sarnabar 15/6 is pre-punched with 6 mm diameter and 15 mm holes, alternating at 25 mm centres to speed installation.

• Peelstop 15/6: 1 mm thick linear bar, used at the perimeters and angle changes of adhered systems, to prevent membrane peel at vulnerable roof areas. 2.125 m x 30 mm Peelstop 15/6 is made from a roll formed and knurled steel strip galvanized to EN 10142-FeP03GZ275N. It is pre-punched with 6 mm diameter and 15 mm holes, alternating at 125 mm centres to speed installation.

• Bar end washer: 90 mm diameter galvanized steel washer, for use at the end of intermediate perimeter rows of Sarnabar to prevent damage to the membrane.
