Much better now. It would help greatly to tell us what in the world you are trying to repair or re-fasten here. But what project do you have in mind here? What fasteners are you looking to replace?
For what? And also remember that different metals in contact each other can cause faster corrosion in one of the metals. So unless you know what specific metal the fastener is being fastened into , you should probably stick with whatever is stock. I see no one mentioned corrosion caused by electrolytic action - that is the difference in electrolytic potential.
You can see this on alloy wheels with steel balance weight clips. The galvanic corrosion is definitely something to be concerned about. Different metals and alloys of metal react differently. There are dozens of alloys of stainless steel alone although probably only a limited few in the fasteners of interest. Also, as mentioned, different metal respond differently to stress. A strong but brittle material could cause more harm than good. My gut tells me that galvanized is probably your safest bet and cheapest.
Also, those plastic push pins would be a no-brainer if they are strong enough for your application. Do not use copper on steel or aluminum under any circumstances!
I always knew these materials were incompatible but figured how bad can it be? I have electric fencing at my farm and the cheapest type of wire is galvanized steel. I had several different heights of posts and decided to add an extra line of wire above the others to keep the goats from jumping over the top.
See our range of corrosion resistant fasteners. If you want to know more about the corrosion-resistant fasteners and materials we can provide, please give us a call. Whilst we may not stock fasteners in some of the materials, we are able to offer them to you as a special. Available now from Fastenright, Sealing Rivet Nuts remove the need for washers by hosting an under head peripheral seal. Find out more information here. There is an extensive list of possibilities available, which we will cover below.
Popular Materials for Corrosion Resistant Fasteners There are a number of popular materials that have anti-corrosion properties. Stainless Steel Both A2 and A4 stainless steel host corrosion resistant properties due to the high levels of chromium within the alloy. Titanium Titanium has excellent stress corrosion cracking, high corrosion resistance, as well as a number of other corrosion resistant features.
Duplex and Super Duplex Duplex and Super Duplex Stainless Steels are becoming more and more common within the fastener industry for a number of reasons, namely greater corrosion resistance and resistance to stress corrosion cracking.
Inconel Like Titanium, Inconel has a number of grades that all host different properties and the majority of these grades are used frequently as fasteners or fixings alongside chemical exposure due to the anti-caustic corrosion properties the material has.
Incoloy Incoloy belongs to the same family of superalloys as Inconel, but both possess distinct properties. Each of the grades has different resistances to different corrosions, which we will list below: Incoloy contains nickel, chromium and iron and is resistant to high-temperature corrosions, including oxidation and carburisation.
Other Materials For Corrosion Resistant Fasteners Hastelloy is a nickel-molybdenum alloy, that like Inconel and Incoloy, is available in a wide range of grades that are all highly resistant to corrosion.

A better option is a steel fastener with a non-sacrificial coating. One way this is done is with a powder coat. Powder coating bakes a thin coat of powder into a solid coating on a workpiece.
There are also other non-reactive coatings that protect steel from atmospheric oxygen. One example is the OWT timber screws from OZCO Building Products , which in lieu of galvanization use a proprietary rust-resistant coating that insulates the screw from atmospheric chemistry and is guaranteed not to rust.
These are self-drilling screws with widely threaded tips to drill through the wood, and smooth shanks to keep from splitting the wood.
OZCO also sells other corrosion-resistant fasteners and accessories, such as hex cap nuts and timber bolts , that use a black powder coat for a protected surface and a clean, attractive appearance. These fasteners will make any project faster and easier to put together, and—if necessary—easy to maintain and repair, too. Very informative article. Rusting or corrosion is a disaster in the world metals or steel. If not taken action against corrosion in initial stage it will be very harmful for metals.
Great to learn about the types of rusting. Thanks for sharing this article. Amazing technologies are coming which are fully corrosion free. Thanks for sharing.
