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.

Beside this, what kind of bolts do not rust?

4 Answers. The stainless steel screw will absolutely be the best screw to resist rust. Stainless steel screws are rust-resistant throughout the entire screw, not just on the surface.

Secondly, are zinc bolts strong? The Strength of HDG Zinc Hot-dipped galvanized zinc metal alloy screws (boy that is a mouth full) have a tensile strength of 62,000 PSI, since they are grade 2 bolts. There are, however, more expensive versions of zinc bolts such as grade 5 and grade 8 that are common.

Also asked, can zinc bolts be used outside?

Zinc plating is rarely sufficient for exposed outdoor use, especially in a marine environment. For underwater use forget it. No other corrosion resistant coating will be as inexpensive as zinc plating though.

What is better zinc plated or galvanized?

The big difference is thickness: zinc plating is normally 0.2 mils thick. Hot dip galvanizing might be 1.0 mil thick – you get over 5 times the protection with galvanizing. The galvanized product will develop a white protective coating (zinc oxide) that adds to its protective properties.
