SELF-TAPPING SCREWS – Professional Fixing Solutions

Self-tapping screws represent one of the most versatile and effective solutions for the quick and secure fastening of metal and plastic materials, without the need for pre-existing threads.

Features and Operation

Thanks to their sharp point and high-penetration thread, these screws create an internal thread directly in the material, ensuring a strong, tensile-resistant connection. They are ideal for thin sheet metal, light alloys, rigid plastics, and pre-drilled supports.

Available Types

The screws are available in various configurations to adapt to any application requirement:

  • Head: cylindrical, countersunk, countersunk with cap, hex, hex with flange, dome head, dome head with flange
  • Impression: Phillips, Pozi, 6-lobe, slotted screwdriver, Phillips screwdriver combination, 6-lobe screwdriver combination
  • Materials: galvanized steel, A2 stainless steel, A4 stainless steel, AISI 410 hardened and tempered
  • Finish: galvanized White, black, phosphated, and other treatments available upon request.
  • Diameters from 2.2 to 6.3 mm, lengths from 4.5 to 150 mm.


Typical applications

These screws are used in numerous sectors, including:

  • Light and metal carpentry
  • Assembly on aluminum and steel profiles
  • Installation of electrical and electronic components
  • Automated industrial assembly

How to Purchase

Consult our technical catalog to identify the most suitable screw. For quote requests, attach the code or technical specifications and send them to: info@milanoviti.it. Our technical team is available to help you choose the ideal fastener.

FAQ – Self tapping screws

Self-tapping screws are fasteners designed to create their own thread in the material they are screwed into. No pre-existing thread is required: the screw cuts directly into the pilot hole, ensuring a solid and secure fit.

  • Self-tapping: creates the thread, but requires a pre-existing hole
  • Self-drilling: has a drill tip that drills and threads in a single step

Self-tapping screws are suitable for:

  • Sheet metal (steel, aluminum, stainless steel)
  • Rigid plastic
  • Soft wood
  • Composite materials (with pre-drilled holes)

The most common configurations include:

  • Cylindrical head
  • Countersunk head
  • Countersunk head with cap
  • Hexagonal head
  • Hexagonal head with flange
  • Round head
  • Round head with flange

With Phillips cross recess, Pozi cross recess, 6-lobe recess, screwdriver recess, cross screwdriver combi recess, 6-lobe screwdriver combi recess


Self-tapping screws are available in:

  • Galvanized steel (white or black)
  • A2 stainless steel (non-aggressive outdoor environments)
  • A4 stainless steel (marine, chemical environments)
  • Aisi 410 tempered (these are stainless steel screws that undergo heat treatment to increase mechanical strength)

The main parameters are:

  • Material to be drilled
  • Diameter and length
  • Type of head and footprint
  • Finish and corrosion resistance

Upon specific request, our staff can provide you with all the details for ideal conditions of use.

Yes, for self-tapping screws, a correctly sized pilot hole is recommended. Self-drilling screws, on the other hand, can drill directly.

Not recommended: after initial use, the thread in the material may no longer guarantee an optimal seal. In some cases, a slightly longer screw or one with a larger diameter can be used.

You can send a request to info@milanoviti.it indicating:

  • Quantity required
  • Dimensions and finish
  • Any technical drawings or item codes

Our technical-commercial staff will respond promptly with customized quotes.
