Electropolishing for Improved Fit, Function & Appearance of Metal Fasteners
Bolts, screws and other metal fasteners are essential to the structural integrity of a wide array of components, from steel fabricated structures to the infrastructure of public utilities. A fastener with a poor finish or one that is prone to corrosion can threaten the integrity and safety of far more than a single bolt or screw. That is why the choice of finishing methods for metal fasteners is critical. The options include a variety of methods, driven by factors that include appearance, the risk of corrosion and part failure and cost-effectiveness.
For fasteners in applications where failure is not an option, electropolishing stands out for its ability to remove a microscopically precise amount of surface material, removing discoloration, contaminants and defects left behind by forging and machining, including micro burrs, microcracks or scratches. The result is a shiny, ultrasmooth and defect free surface that provides enhanced corrosion-resistance and decreased risk of part failure.
