There is a wide variety of wood screws available, but they are all used for the same purpose: fastening wood together. They are able to process chipboard, MDF, softwood, and hardwood.
There is a wide variety of wood screws on the market, some of which contain shanks to prevent wood splintering, twin threads for a powerful drive, and tips that eliminate the need to pre-drill holes. Wood screws are available with a number of different head designs and drives.
The countersunk head and Pozidriv styles, however, are the most widely used. Wood screws were first manufactured from brass or steel, and their shafts tapered toward the head. For this particular type of screw, a pilot hole was required to ensure a tight fit.
But today’s wood screws have a uniformly sized shank in comparison to the head.
Sizes of Various Wood Screws
Choosing screws of the right size is crucial. Select screws whose width is equal to or more than that of the wood you’re using. Check if the screw can withstand the intended load before using it.
The number indicates the screw’s diameter or gauge; #6, #8, and #10 are the most popular sizes. The thickness of the screw is proportional to the higher numbers. If you’re looking for a rough guide, the #8 screw is ideal for most applications, while the #6 screw is excellent for precision joinery.
Types of Wood Screws
Screws for wood can be found in either a partially threaded or fully threaded kind. Steel screws are widely regarded as the gold standard for use in woodworking and indoor home improvement projects due to their durability and adaptability.
Nowadays, “production screws” are frequently used for this function. They have sharp, defined tips and threads that can easily pierce even the hardest woods. The strength of these screws allows them to endure powerful drilling and driving.
Because of the pointed tip, wood screws may be driven into the wood with great accuracy. Screws may be driven in safely since their threads completely encircle the shank. Fine threads should be used for hardwoods, whereas coarse threads should be used for softwoods and plywood.
Head Types for Wood Screws
The form and drive type of a screw head is its most defining features. Several different types of drives exist, however, the most common ones are listed here.
Driven screws of the slot head form are the most prevalent type. The material can be pierced by simply twisting the slot with a flathead screwdriver.
Philips head screws are far more versatile than slot head screws. They are designed to fit securely into a variety of woods. The last bit of the screw being driven into the wood, however, may slip. The screw and the driver frequently break as a result.
Robertson or square drive screws offer several benefits over Phillips head screws. The square shape of the head of these screws makes them much less likely to become dislodged. Common uses include pocket screws.
For use in wood, star head screws have also gained popularity. Torque levels well into the thousands of rpm range are no problem for these components, and their dependability ensures they can be installed with confidence.
Classifying Wood Screws by Material Type
Wood screws, as was said before, can be found in a variety of materials. Screws of many materials, including brass, bronze, and aluminum, are commercially available. But steel screws are by far the most popular and ubiquitous type.
Many customers opted for less expensive screws for plasterboard because of the problems that came with using typically tapered steel wood screws. Without the need for pilot holes, these screws may be quickly inserted into drywall and studs. There was a problem, though; they were extremely fragile and prone to breaking under stress.
Many people have switched to using current production screws as an alternative to plasterboard screws because of the issues that have been reported while using plasterboard screws. These screws are sturdy and dependable, capable of penetrating several wood species and even some metals. They’re sturdy enough to handle speedy driving, too.
Due to its strong corrosion resistance, steel deck screws are frequently utilized for outdoor applications. Where corrosion is a major concern, silicon bronze or stainless steel screws might be used instead.
