Corrosion resistant bolts are regular bolts made of corrosion resistant alloys and metals like titanium, copper, brass, stainless steel, bronze, aluminum alloys and steel, coated with nickel. Use of corrosion resistant bolts saves joints from corrosion that occurs because of a chemical attack on metal by atmospheric gases, moisture and other chemicals.

Equipment that has a corrosion resistant bolt as a necessary part are acoustic equipment, orthopedic implants, dental and medical instruments. Various industries that use corrosion resistant bolts are pharmaceutical, aerospace, semiconductor and marine industries.

Some important parameters you must consider before you buy a corrosion resistant bolt are:

1. Corrosion compatibility of bolt material with the joint material
2. Required dimensions to suit the other parts of the equipment
3. Required quantity of corrosion resistant bolts
4. Operating environment

The best contacts and resources to help you get it done

Buy corrosion resistant bolts from reputable bolts manufacturers

Once you understand your requirements, check out standard corrosion resistant bolts available in the market. You can also search for a corrosion resistant bolts manufacturer that supplies bolts for specific applications. For example, a corrosion resistant bolt for an orthopedic implant must have high wear resistant properties, as its frequent replacement is not possible.

I recommend: United Titanium, a manufacturer of fasteners, offers corrosion resistant bolts made of titanium, zirconium, nickel alloys and cobalt alloys. You can buy corrosion resistant bolts from Vegas Fastener Manufacturing, another fastener manufacturer catering to various industries such as power, marine transportation, food processing and utilities.

Buy corrosion resistant bolts from reputable bolt distributors or retailers

You can compare different corrosion bolts based on the corrosion resistant bolt price and the additional features at bolt distributors and retailers. Look for corrosion resistant bolt supplier that offers economical pricing.

I recommend: Wink Fasteners, a corrosion resistant bolts distributor can supply bolts made of stainless steel. You can buy corrosion resistant bolt online from Bolt Depot, a reputable fastener distributor.

Buy customized corrosion resistant bolts

For non-standard requirements such as extra length or very small bolt head diameter, opt for specialty or customized corrosion resistant bolts.

I recommend: Chicago Industrial Fasteners is a reputable industrial fastener manufacturer that can provide customized bolts according to your needs. Ocean State Stainless is another supplier of non-standard fasteners made of nickel and other non-ferrous materials.

Tips & Tactics

Helpful advice for making the most of this Guide

• •  Make sure your corrosion resistant bolts supplier follows the standards adapted by your design engineers.
• •  Refer to the bolt manufacturers' instructions about the maximum allowable torque for the corrosion resistant bolt. Bolt manufacturers generally indicate it symbolically on bolt heads.
