Frequently Asked Questions (FAQs)

1. Are zinc bolts good for outside?

While zinc plated bolts and nuts are considered resistant to corrosion and have a number of suitable applications outdoors and within the industrial sphere, zinc plated nuts are not suitable for use in marine environments or in environments where humidity is higher than average.

2. Are zinc coated bolts rust proof?

Zinc Plating Fasteners that have been zinc plated have a shiny, silvery or golden appearance, referred to as clear or yellow zinc respectively. They are fairly corrosion resistant but will rust if the coating is destroyed or if exposed to a marine environment.

3. Are stainless steel bolts stronger than zinc plated?

Though more expensive, stainless steel is a strong, tough material noted for its corrosion resistance. Though some Zinc alloys can be very strong, overall stainless steel is stronger.
