Turbo screws – or how to screw a screw into concrete

Ever attempt to hammer a screw through concrete? If so, you are aware that it’s not as simple as screwing into drywall or wood. Regular screws find concrete challenging due to its hardness and reluctance to yield. Nevertheless, turbo screws offer a remedy. Securing objects to concrete surfaces is much easier with these specially designed fasteners.

For both pros and DIY enthusiasts, turbo screws are revolutionary. They have a special thread design that pierces concrete to offer a stable and robust hold. No need for difficult instruments or methods. Turbo screws make it easy to hang shelves, mount fixtures, and finish other projects.

We’ll walk you through the process of using turbo screws in concrete in this article. Everything from selecting the appropriate screw to the most effective methods for inserting them will be covered. Regardless of your level of experience, you’ll find useful pointers and recommendations to help your next project succeed.

Aspect Details
Tool Required Hammer drill with masonry bit
Drilling Drill a hole slightly smaller than the screw diameter
Inserting Screw Insert turbo screw with a screwdriver or impact driver
Securing Tighten the screw until it is flush with the concrete surface
Use Ideal for attaching items directly to concrete

Types of screws

Concrete fasteners vary in a few key areas.

They are separated into screws based on how the cap (head) is configured:

  • with a hidden cross-shaped cap;
  • with a hexagon-shaped cap (equipped with cross-shaped slots, differ in internal thread, the key can be open-end or socket);
  • studs, which have a shorter thread on one side than on the other (they are also called couplings);
  • crocodile (they differ in the head, which can be round or rectangular).

The fastener installation procedure is impacted by the hardware’s head shape. In the event that hooks and studs are utilized, they have to be screwed into a sealing material-filled, pre-drilled hole. Drilling is not necessary for fixing any other products; just some preliminary preparation is needed.

Also, the kind of protective coating used on self-tapping screws for concrete varies. These fasteners can be easily identified by color:

  • Black – covered with an oxidized film. Such products are suitable for rooms with low air humidity.
  • Silver – treated with zinc compounds. Self-tapping screws of this color are considered the most universal, as they are resistant to corrosion. These products are suitable for both external and internal work.
  • Yellow – covered with a zinc protective compound with the addition of brass and copper. Fasteners of this type are suitable only for indoors.

The thread on self-tapping screws is an important consideration when selecting them for concrete. Fasteners are classified according to this parameter into:

  • Universal (d 3-6 mm). The length of such screws ranges from 12 to 220 mm. The rod is a standard helical groove. These fasteners are suitable for surfaces made of porous and heavy concrete. In the latter case, it is necessary to prepare the mounting hole (the screw is placed on the dowel).
  • Universal with a "herringbone" thread (d 3-8 mm). Self-tapping screws from 12 to 200 mm long are installed in the mounting holes into which the polymer sleeve is "tucked". In this case, the depth of the hole should be 3-5 mm greater than the fastener itself. Such products are driven in using the impact method or with a conventional screwdriver.

Fasteners that don’t need any initial setup are taken into account individually.

Variable-threaded screws (d 5 mm) are also frequently referred to as dowels, turbo screws for concrete, or self-tapping screws without drilling. These items are constructed from incredibly durable materials, such as brass, carbon, or high-strength stainless steel, and they have been galvanized, or coated in a yellow protective layer, to stop corrosion.

The variable thread with notches is the primary characteristic that sets the dowel apart. The coefficient of adhesion to the concrete surface rises as a result. To screw the dowel in, all you need is a screwdriver.

Turbo screws range in length from 52 to 212 mm, have a cross-shaped head width of 11 mm (products with a head shaped like a star, barrel, or hexagon are also available), and have a cross-sectional diameter of 7 mm that remains constant in length.

Practical! The dowel’s load-bearing capacity increases with installation depth.

Turbo screws are typically utilized when working with hollow blocks and porous concrete.

Aside from hardware type and color, there are a few other considerations that should be made.

What to look for when choosing fasteners and a drill

Self-tapping screws for concrete are virtually identical to regular screws from the outside. Nonetheless, products that are appropriate for installation in concrete surfaces need to have a few unique qualities:

  • Material of manufacture. You should only select those hardware that were made of high-quality steel.
  • Hat. Depending on the tool you plan to use, you need to select the shape of the hardware head. For example, "cross" and "star" are suitable for a screwdriver and a screwdriver (such heads are very convenient when you need to apply a lot of force when tightening).
  • The tip of the screw must be sharp.

If screws aren’t treated with an anti-corrosion compound, rust will soon form on them and eventually spread to the wall’s reinforcing frame, if one exists.

In the event that a hammer or electric drill is used to tighten the screw, the drill should be chosen according to the following standards:

  • the diameter of the product must be 2-3 mm smaller than the cross-section of the screw;
  • It is allowed to use a universal drill for an electric drill;
  • if you are going to use a hammer drill, it is better to buy a special drill with grooves on the cylindrical surface of the tail.

Additionally, you must determine the load that the fastener can support before purchasing hardware.

The cost of the goods is the final factor.

An excellent option for fastening objects to concrete are turbo screws. As a result of their simplification, the procedure is quicker and more effective than with conventional techniques. These screws’ distinctive design offers a firm grip without the need for plugs or anchors.

Turbo screws are simple to use. You can easily make a pilot hole with the right tools, such as a hammer drill and the right bit. The turbo screw can then be easily inserted into the concrete. This approach saves time and effort, especially for professionals and do-it-yourselfers alike.

In general, turbo screws provide a dependable and simple method of attaching objects to concrete surfaces. They are a great option for many building and remodeling projects because of their efficiency and convenience. Turbo screws are a dependable choice whether you’re hanging shelves, installing fixtures, or working on more significant structural tasks.

Turbo screws are a quick and practical way to firmly attach items to concrete surfaces. In contrast to conventional techniques that necessitate anchors or plugs, turbo screws are made to be driven straight into concrete, offering a stable and robust hold. This post will explain how turbo screws operate, what equipment you’ll need, and how to use them step-by-step in your projects. By doing so, it will be easier for professionals and do-it-yourselfers to approach concrete fastening with confidence.
