Stainless Steel Fasteners: Types, Grades, and Industry Applications

This page provides an overview of stainless steel fasteners, including bolts, screws, nuts, washers, and rivets, made from chromium-alloyed steel for corrosion resistance. It covers common types and their uses: bolts/nuts for removable joints, screws for direct threading, washers for load distribution, and rivets for permanent connections. Key grades (304, 316) are explained, with 316 offering superior saltwater/chemical resistance. Applications in food processing (hygiene), marine (saltwater), and outdoor construction (moisture) are explored, along with factors affecting corrosion resistance (alloy content, surface finish). Essential for anyone needing durable, low-maintenance fastening in harsh environments.

Frequently Asked Questions

What factors affect the corrosion resistance of stainless steel fasteners?

Corrosion resistance of stainless steel fasteners is affected by the chromium content (higher chromium enhances resistance), presence of other alloying elements (molybdenum in 316 improves saltwater resistance), environmental conditions (chlorides, acids, humidity), and surface finish (polished surfaces resist corrosion better than rough ones). Damage to the oxide layer (e.g., scratches, abrasion) can expose the underlying metal to corrosion, though the layer can self-heal if oxygen is present. Improper cleaning or contact with incompatible metals (e.g., carbon steel) can also reduce corrosion resistance.

Benjamin Wilson

This stainless steel fastener kit is a must-have for anyone working in coastal or industrial environments. It includes bolts, screws, nuts, and washers in various sizes, all in 304 stainless steel. I used them for a seawater pump installation, and the corrosion resistance has been excellent—no pitting or rust after a year of exposure. The organized case makes it easy to find the right fastener quickly, though I wish it included more specialty items like lock nuts. Overall, a convenient and reliable set for any project where rust is a concern.
