Stainless Steel Bolts: Grades, Corrosion Resistance, and Uses

This page focuses on stainless steel bolts, made from chromium-rich alloys (≥10.5% chromium) that form a protective oxide layer, resisting rust and corrosion. It details common grades: 304 (mild environments), 316 (saltwater, chemicals with molybdenum), and 410 (high-strength, low-corrosion). The content explains when they’re preferred over carbon steel—outdoor, marine, chemical, or food processing settings—and covers advantages (durability, low maintenance) and disadvantages (cost, galling risk). Installation tips to prevent galling (lubrication, proper torque) are included, along with insights into selecting the right grade for specific environmental and load needs.

Frequently Asked Questions

How to prevent galling in stainless steel bolts?

Galling, a form of wear where threads seize and tear, can be prevented in stainless steel bolts by using proper installation techniques: applying anti-seize lubricants (e.g., graphite, molybdenum disulfide) to the threads, avoiding over-tightening, and using compatible materials (e.g., stainless steel nuts with stainless steel bolts). Using finer threads (which reduce friction) and ensuring clean, debris-free threads also helps. Additionally, avoiding rapid or excessive torque and using bolts and nuts of the same grade (or compatible grades) minimizes the risk of galling, ensuring smooth installation and preventing thread damage.

customer evaluation

Nathan Taylor

I used these stainless steel bolts for a backyard fence made of steel posts and wooden panels, and they've been outstanding. The 304 grade resists rust from rain and sprinklers, and the hex heads are easy to tighten with a wrench. The fully threaded design allowed me to adjust the nut position along the post, ensuring a secure fit for the panels. After three years, the bolts look as good as new, with no discoloration or corrosion. For any outdoor project where longevity is key, these bolts are a wise investment.
