Tapping Screws Catalog

Threaded screws are a type of screw that has a helical groove in the shank, which allows it to be secured using a tool called a screwdriver. Threaded screws are used to join pieces of wood, metal, plastic or other materials by creating an internal thread in the hole where the screw is inserted.

There are different types of self-tapping screws depending on their shape, size, material and use. Some of the most common are:

Flat head screws

They have a flat, smooth head, which is flush with the surface once screwed in. They are used to join pieces that do not require an aesthetic finish or that are covered with another layer.

Round head screws

They have a round and domed head, which protrudes from the surface. They are used to join pieces that need strength or that are visible to the naked eye.

Countersunk head screws

They have a conical head, which sinks into the surface when screwed. They are used to join pieces that require a smooth and uniform finish.

To choose the right tapping screw for each job, several factors must be taken into account, such as:

The material of the pieces to be joined

Depending on the material, a more or less resistant screw may be needed, with a more or less sharp tip, or with a special coating to prevent corrosion.

Screw diameter and length

Depending on the thickness and depth of the pieces to be joined, a more or less thick and long screw may be needed to ensure good fixation and prevent it from protruding or falling short.

The type of head and the tool to use

Depending on the type of screw head, you may need a flat, star, hexagonal, or torx screwdriver, among others. In addition, you must choose a head that adapts to the desired finish and the available space.

Tapping screws are essential elements in many DIY, carpentry, mechanical or electrical jobs. Therefore, it is important to know its characteristics and know how to choose the most appropriate one for each case.
