Grooved nails

Introducing the grooved nail

A fluted nail is a type of nail whose shank is equipped with grooves or flutes. These notches improve resistance to shrinkage, enhancing the nail's effectiveness in holding materials firmly together. They are frequently used in applications where additional adhesion is required, notably in :

  • Framework construction
  • Joinery
  • Fixing insulating materials.
  • The grooves on the nail provide a better grip on the material, improving the stability of the assembly thanks to elastic tightening.

The grooved nail shank has a bulge diameter greater than its nominal diameter, and the receiving part, whose diameter is slightly smaller than the bulge diameter, allows the metal to flow, thus promoting optimum clamping.

How is a Gardette grooved nail made?

The production of grooved nails generally involves the use of cold heading, a process that deforms metal at room temperature into the desired nail shape. Initially, the metal is cut into precise lengths before being fed into a coining machine where it is subjected to impacts.

A second operation involves striking between dies to form the flutes. 

This process creates the grooves and reinforces the metal, improving the nail's strength and durability.

Finally, grooved nails can be given a finishing treatment, such as galvanizing, to protect them against corrosion. Rigorous inspection ensures compliance with quality standards before final packaging and shipment of ready-to-use nails. It is important to note that manufacturing techniques may vary according to the specifications and type of grooved nail.

The different fluted nails

There are different fluted nails with different characteristics, shapes and sizes:

Characteristics of iso 8746 grooved nails

The iso 8746 grooved nail has grooves on its surface to increase the hold between the hole and the material into which it is driven, and its bulge diameter adapts to the housing without removing material.

The iso 8746 grooved nail is made from steel, but can be manufactured in other materials on request. 

This piece has a special feature: its head is round and slightly larger than the stem, which offers a number of advantages:

  • Resistance to twisting: The round head with a slightly larger size than the stem is more difficult to deform.
  • Puncture resistance: the round head protects the shank from puncturing, preventing it from breaking when the nail is driven in.

This part is used in a wide range of industries, including :

  • Construction: The round head of the iso 8746 spline nail is ideal for fastening beams, columns and walls. The friction resistance of the iso 8746 grooved nail meets the fastening needs of these elements.
  • Joinery: The round head of the iso 8746 grooved nail is ideal for fastening doors and cabinets. The torsion resistance of the iso 8746 grooved nail meets the fastening needs of these elements.

Characteristics of ISO 8747 grooved nails

The iso 8747 grooved nail has grooves on its surface to increase the hold between the hole and the material into which it is driven, and its bulge diameter adapts to the housing without removing material.

The iso 8747 fluted nail is made from steel, but can be manufactured in other materials on request. 

This part has a special feature: its head is milled wider than the nail shank, which offers a number of advantages:

  • A clean finish : The countersunk head of the nail is slightly recessed into the material, giving a neat finish.
  • Low risk of protrusion: The width of its head reduces the risk of protruding after sinking.
  • Very little vibration: The countersunk head, slightly recessed into the material, reduces vibrations and also absorbs them.

This part is in demand in sectors where a clean, neat finish is mandatory, such as : 

  • Repair: A clean, neat finish is important in construction. To offer customers a clean finish, the iso 8747 grooved nail is highly recommended in this sector.
  • Decorative applications: A neat, clean finish is essential for decorative applications, and the iso 8747 grooved nail is highly recommended in this sector.

What is a grooved nail?

A grooved nail is a type of nail whose shank is grooved or fluted. These grooves increase resistance to shrinkage, making the nail more effective at holding materials firmly together. They are often used in applications where extra grip is required, such as in : 

  • Framework construction
  • Joinery
  • Fixing insulating materials.

The grooves on the nail provide a better grip on the material, improving the stability of the assembly through elastic tightening. 

The splined shaft has a bulge diameter greater than its nominal diameter, and the receiving part, whose diameter is slightly smaller than the bulge diameter, allows the metal to flow, thus enabling optimum clamping. 

How do you make a grooved nail? 

Manufacture of grooved nails iso 8747 and iso 8746 generally involves cold heading, a process which deforms metal at room temperature into the desired nail shape. The metal is first cut into precise lengths, then inserted into a coining machine where it is struck

A second operation strikes between dies to form the splines. This process not only forms the splines but also strengthens the metal, increasing the nail's strength and durability.

Finally, nails can be finished, such as galvanized, to protect them from corrosion. Rigorous inspection ensures compliance with quality standards before final packaging and shipment of ready-to-use nails. It is important to note that manufacturing techniques may vary according to specifications and the type of grooved nail.
