There are a ton of metric fasteners on the market that you can use in projects, including nuts, screws, and bolts. If you want to make sure you're choosing the right variety to work with, here are some insights that can help out.

Start With Choosing the Right Type

Before you get into the more specific details of a metric fastener like coating and material, you want to start out by choosing the right type. There are a lot of choices, but if you take enough time assessing the specific project you're supporting, you can figure out what fastener type will give you the best results.

For instance, if you're looking to combine heavy-duty materials together, a thick metric bolt might suffice. Whereas if you're just trying to keep a screw from loosening over time, a metric washer would be the best choice. 

See What the Environment Dictates For Material 

Once you figure out what type of metric fastener to work with, you need to determine an appropriate material. You have options like carbon steel, mild steel, aluminum, brass, and a bunch of alloys. If you want to have an easier time narrowing down these choices, think about what your environment dictates.

You may be setting metric fasteners up outside around wet conditions and in that case, you need a material that can protect against corrosion. Or maybe your metric fasteners will be around a system that gets extremely hot and thus need to be made out of a material that's heat-resistant.

Get Professional Recommendations With Size

Choosing the right metric fastener size isn't going to confuse you at all if you just get professional recommendations when trying to work out this spec. Professional fabricators that work with metric fasteners all the time can help you find the right size to where these fasteners work out great regardless of what they're being used for.

You just want to have as many project details ready to go as possible, such as what you're doing with the metric fastener and where it's going exactly. Then you'll get relevant size recommendations that lead to a smoother fastener setup.

There are some key factors you need to take a look at closely when choosing metric fasteners. As long as you don't rush this search process, you'll make the best selections and then be able to work with metric fasteners in an uninhibited manner each time.
