Chicago screws anodized aluminum screw posts brass screws

Chicago screws are traditionally used for binding photo albums, swatch books, and wine menus, but are also great for binding oversized documents like manuscripts or blueprints, design portfolios, and scrapbooks! Chicago Screw posts are perfect for almost any application where loose pages need to be kept together! Ever Hardware offers Chicago screws in SILVER, BLACK, GOLD, or ANTIQUE BRASS, and PLASTIC screw posts in either white or black. 

Anodizing (also spelled anodizing, particularly in the UK, India, and Australia) is an electrolytic passivation process used to increase the thickness of the natural oxide layer on the surface of metal parts.
The process is called anodizing because the part to be treated forms the anode electrode of an electrical circuit. Anodizing increases resistance to corrosion and wear and provides better adhesion for paint primers and glues than does bare metal. Anodic films can also be used for a number of cosmetic effects, either with thick porous coatings that can absorb dyes or with thin transparent coatings that add interference effects to reflected light. Anodizing is also used to prevent galling of threaded components and to make dielectric films for electrolytic capacitors. Anodic films are most commonly applied to protect aluminum alloys, although processes also exist for titanium, zinc, magnesium, niobium, zirconium, hafnium, and tantalum. Iron or carbon steel metal exfoliates when oxidized under neutral or alkaline micro electrolytic conditions; i.e., the iron oxide (actually ferric hydroxide or hydrated iron oxide, also known as rust) forms by anoxic anodic pits and large cathodic surface, these pits concentrate anions such as sulfate and chloride accelerating the underlying metal to corrosion.
