We carry steel screwposts in two styles:
Standard steel screw posts are the same size and shape as our industry standard aluminum screw posts. You can use these interchangeably with aluminum screw posts, anywhere you need the greater strength of steel. They have the same low-profile heads as the industry standard screw posts, so they will not interfere with document covers or bindings designed for standard screwposts.
Heavy duty round head screw posts are thicker and heavier than our industry standard aluminum screw posts. They also have a rounded (domed) head instead of the flattened head that the standard screwposts have. These are normally used only when the highest strength is needed, such as for holding carpet samples and other extremely heavy materials.
