Flanged general-purpose screw 8x40 ZP WAF13 serrated

Hot-dip galvanized heavy-duty wood screw suitable for demanding fastening applications. The serrated flange bites into the metal during installation and helps prevent the screw from loosening. The patented thread with drilling and cutting action speeds up fastening. The fiber-cutting tip allows installation close to the edge without the risk of splitting the wood. Provides a secure hold and a durable end result even in demanding structures over the long term.
