Stainless Steel Self-Drilling Screws

These have a star-shaped head that helps them drill their hole into the surface they’re being driven into, so you don’t need to pre-drill. 

They’re often used for outdoor projects like decking and fencing, where moisture can cause regular screws to rust.

Stainless Steel Sheet Metal Screws

These have parallel threads, so they won’t spin out of place when driving them into sheet metal or thin metal plates (like aluminum). 

They’re also great for attaching plastic trim pieces because they won’t leave any unwanted holes behind in thin plastic after you remove them again later.

How to Determine the Size of the Screw for a Shipping Container

Shipping containers have a standard size and screw holes designed to accept a specific size of screw. If you have no idea what size screws to use, we recommend using 1/2″ x 3/8″ flathead screws.

They are common and available at most hardware stores. You should be able to find these in any length up to 2″.

Determining the Correct Length of the Screw for a Shipping Container

The thickness of your material determines the length of your screw. The more material you need to penetrate, the longer your screw will be. 

Also, consider the thickness of your drill bit for drilling pilot holes for your screws. This can affect how much material will be removed from the hole, which helps determine how long your screw needs.

Things to Consider Before Choosing a Screw Type for Your Shipping Container

There are various types and sizes of screws. When choosing a screw to use in your project, it’s essential to consider the following factors:


Different materials have different properties that affect how they can be fastened together. 

For example, metal is stronger than wood but harder to drive into; therefore, you’ll need a different type of screw if you fasten metal onto wood or vice versa.

Head Type

The head of a screw is the part that prevents it from falling out once it’s been driven in place. 

Choosing a head type depends on what kind of surface you’re driving into, if it’s a soft material like wood or plastic, then a flathead screwdriver will work best; if it’s hard material like metal or concrete, then you’ll need something with a more aggressive grip like an Allen key or hexagonal wrench head.

Thread Pitch

This refers to the distance between threads on the screw’s shank or body. The higher this number is, the more torque can be applied without damaging the threading. 

Piston screws have a higher thread pitch than other types because they’re designed for heavy-duty applications like holding large equipment or machines carrying heavy loads.


The diameter of a screw refers to its thickness from top to bottom. A large-diameter screw will have more threads per inch than a small one, which means it will be more robust and expensive because it requires more material.
