SF inserts are recommended for Wood and Composite applications. Their geometric shape and sharp pointed fluted fins eliminates any danger of the substrate splitting on installation or when tightening of the mating screw occurs. They provide lower screw installation torque than the FV type due to the points created by the fluting of the fin. The points allow easier penetration into the substrate. A short version is available for use in restricted circumstances. The distance from the edge of the product to the outside of the hole diameter should generally be at least that of the insert diameter.
Different materials may require slight modifications to the hole dimensions stated above and it is essential that the hole depth is sufficient to allow the screw to pass completely through the insert to achieve optimum performance.
