Binding Posts - Aluminum

These are the standard sex bolts developed originally for the printing industry, and used to bind catalogs together. Standard size is the 8-32 with .203" diameter barrel. We also stock the non-standard Stainless Steel, Brass and Copper items, for when increased strength or a different look is needed.
