Fasteners Etc., Inc. offers square head bolts in grade A strength with multiple finish options- plain steel, zinc, and galvanized. A square bolt is designed with a square head and threaded shaft which can be full or partial depending on the length of the bolt. Installation can be easily accomplished with standard tools, such as a wrench. Most applications will require a pre-drilled hole in the base material; be sure to add bits or nuts if required to complete the project.
