Corrosion-Resistant Fasteners: Stainless Steel, Zinc, and Galvanized Options
The Cost of Rust
Fasteners are small, but their impact is huge. Rusty screws, bolts, and washers can compromise structural integrity, slow down maintenance, and increase replacement costs.
Outdoor projects, coastal environments, and industrial applications require corrosion-resistant fasteners that can withstand moisture, salt, and harsh weather conditions.
At SC Fastening, we stock a wide range of corrosion-resistant options to keep your projects strong and long-lasting.

Types of Corrosion-Resistant Fasteners
Stainless Steel Fasteners
- Long-lasting
- Non-reactive with many metals
- Minimal maintenance
- More expensive than standard steel
- Higher cost than zinc-coated options
Zinc-Coated Fasteners
- Affordable
- Widely available
- Good basic corrosion protection
- Coating can wear off over time
- Not ideal for extreme moisture
- Limited salt exposure resistance
⚪
Galvanized Fasteners
- Extremely durable in harsh environments
- Excellent longevity
- Cost-effective for large projects
- Thicker coating affects threading
- Can affect fastener tolerances
- Heavier than uncoated fasteners
Choosing the Right Corrosion-Resistant Fastener
Assess the Environment
Coastal? Industrial? Wet or humid? Evaluate exposure levels to determine protection needs
Load Requirements
Structural steel vs. light-duty wood fasteners require different strength specifications
Longevity vs. Cost
Stainless steel lasts longest but costs more; zinc is cost-effective for short-term or indoor projects
⚡
Check Compatibility
Avoid mixing metals that can cause galvanic corrosion
