PHEINOX 305 Stainless Steel screws are corrosion and stain resistant – designed to withstand wet environments.

How Much Weight Can A Spax Screw Hold?

Instead, the load is a function of its cross-sectional area. A typical range for proof strength for steel is 50 to 100 kpsi (i.e., a screw with a 1 square inch cross-sectional area of steel can hold up to 50,000 to 100,000 pounds).

How Long Should Screws Be?

The most important factor in screw selection is length. The general rule of thumb is that the screw should enter at least half the thickness of the bottom material, e.g. 3/4″ into a 2 x 4.

How Long Should A 2X4 Screw Be?

A 2×4 is 1-1/2 inches x 3-1/2 inches. If you’re joining them face to face, that’s 3 inches thick. A 3 inch long construction screw is ideal, but if you sink the screw head below the surface too far, the tip will blow out the other side.

Are Deck Screws Strong?

Deck screws are similar to the wood screws, and you will easily confuse the two. The biggest difference is the fact that they have a larger surface area. This will give you a greater capacity to bear load. Decking screws are made of coated steel or copper, which makes them corrosion-resistant.

How Do I Choose A Screw?

Steps to Choosing the Correct Screw: Select a screw size. Choose a thickness that works for the width of the material you’re placing the screw into, as well as the weight the screw may support. Determine the correct screw length. Choose a length based on the depth of the material you are placing the screw into.

A deck screw is a very specific type of screw; ask for a deck screw at a hardware store, and you always get the same basic type of screw. While a construction screw is also a specific type of screw, the term holds generic meaning and can refer to any number of screws, from lag to deck, used for construction projects.

What Is A Structural Screw?

Structural screws or construction screws are thin, high-strength screws made of super strong, heat-treated, sometimes galvanized steel. They are a newer type of structural fastener that can be used in place of lag screws to cut down on the time and effort put into drilling.
