Stainless-Steel Fastener Solutions
When selecting the right fastener for long-lasting, trouble-free service, considering the corrosion risk factors in the project environment is critical. There are a wide range of available fastener materials and coatings that possess varying levels of corrosion resistance and it is important to identify the right one for the intended environment.
Types of Stainless-Steel Fastener Materials
For environments that are at a high risk for corrosion, stainless-steel fasteners are the recommended solution. Simpson Strong-Tie offers an extensive variety of fasteners in types 304/305 and 316 stainless steel that are designed for easy installation and reliable performance.
The information below is intended to clarify which types of stainless-steel fastener materials are suitable for various projects and environments.

Always Use Stainless Steel Fasteners with Stainless Steel Connectors
Even with the protection of stainless steel connections, structures in corrosive environments can be compromised over time when these connectors are installed with fasteners or anchors that are not stainless steel. Carbon-steel fasteners and anchors with coatings such as hot-dip galvanization will corrode faster than the stainless steel connectors, creating a weak link that could eventually lead to repairs or failure. Likewise, fasteners or anchors made from lower grades of stainless steel, such as types 304/305 (aka “18-8 stainless”), are also not recommended for use with Simpson Strong-Tie type 316 stainless steel connectors.
