As wood handypersons, we all have one question, how much weight a deck screw can hold? Well, the answer is not all that straightforward. In the following article, we are going to elaborate on these.
Hence, different kinds of deck screws have different sorts of weight capacities. You must know them to get more advantages out of these tiny pieces.
Either way, keep reading to get to know the weight capacity and related terms in detail. It would be worth your time.
How Much Weight Can A Deck Screw Hold?
Screws are the most important fastener for furniture makers. It works by joining wood parts and making the connection long-lasting. But there are many kinds of screws available in the market. Every kind of screw has different features in length, width, capability material, etc. just like every screw has a different ability to hold wood weights.
Usually, screws can hold 80-100 pounds of weight. But many factors can change the ability of screws. It depends on screw length, thread, quality, and many more. It also depends on how it has been driven, how much force is given, or how tight the screw is.
Which Things Determine How Much Weight A Deck Screw Can Hold
As we all know, screws can hold weight based on their features. Several things can impact this.
Length is the most important thing that can determine how much a screw can hold. It can significantly affect how much a screw can penetrate the wood. A screw must go deep enough to ensure a solid grip. If a screw can’t do that, then the joint of the wood won’t be strong enough. So length has a huge impact on the connection.
There are three sizes of screws available on the market. These are 6, 8, and 10 diameters. It means these are small, medium, and large. So you have to find your preferred size. It depends on the width of the wood. A screw must go half of its width.
Threads are also an essential thing for furniture making. It helps to get a better grip on the joint. There are two types of thread available in markets. These are coarse thread and fine thread.
Coarse threads are durable and have good resistance to stripping. It has more space between each thread. The spaces make engagement more extraordinary. It makes it easier to screw in wood. It is considered the best soft material. But it is not stronger than a fine thread. The fine thread has more ability to hold weight. It has a minor diameter and a larger tensile stress area. It can handle odd angles and less jamming.
Screw Force Type
The force of the screw has a big impact on the amount of weight that it can hold. There are two types of force used in furniture making. These are lateral force and withdrawal force.
The lateral force is also considered a sheer force. It is mainly used when two wooden parts are attached flat. Kitchen wall cabinets are one great example. In this situation, you might need thicker screws. On the other hand, withdrawal force is applied when two materials want to separate. In that case, you might want a long screw that can penetrate deep enough. You might also want to use multiple screws to boost strength.
You have to select screws based on their quality. Strong screws can handle more weight. On the other hand, screws with less quality can hold enough weight. It can cause breakage of wood parts. There are crucial factors that can affect screw quality. Steel alloy and how it was tempered are the most important factors. Thickness also has a great impact on quality. The thick the screw is, the more ability to hold weight. You can judge the tensile strength also.
Make sure you get a high-quality screw; you can buy it from any famous and respected brand. Otherwise, you can buy it from any good retailer or shop.
