Fastener materials are important when selecting a fastener due to differences in strength, brittleness, corrosion resistance, galvanic corrosion properties and cost of the available materials. Substituting a bolt with a stronger one is not always safe. Harder bolts are more brittle and may fail in specific applications; some equipment is designed so that the screws will fail before more expensive or critical items are damaged. In some environments, for example ‘salt water’ galvanic corrosion must also be considered if changing fastener materials. Stainless steel perform differently in different envoronments, it is important to choose the correct material.
