Come take a look at our extensive catalog of conical head nails. You’ll find all types of nails, with smooth, twisted, serrated, or ringed shanks, available in steel or stainless steel. All the tools needed for fixing into concrete are offered by the top brands such as SPIT, DIMOS BATIMENT, TORBEL INDUSTRIE ...

The conical head nail, or countersunk nail, is not a very common type of nail in the world of amateur DIY. The conical structure under the head is designed to create a rigid and solid fixture in full and hard materials (mainly concrete). This nail is notably more rigid than its counterparts, it does not bend.

This tool is available in stainless steel or steel of varying hardness in 4.8 and 14.9. This hardness rating, whose meaning is not so obvious, defines the yield strength and break point of the designated steel. The yield strength represents the limit (calculated in MPa) up to which the steel can be stressed without undergoing permanent deformation; it will return to its initial shape after the effort.

It is calculated as follows: for a rating of 8.8: Yield Strength = 8 x 8 x 10 = 640 MPa.

The break point represents the force necessary to break the structure of the steel.

For a rating of 8.8: Break Point = 8 x 100 = 800 MPa.

There is also a multitude of possible coatings for nails, such as: galvanized, bichromated, brass-coated, sherardized, etc., but the most common is galvanization (hot-dip, cold-dip, centrifuge). This applies a thin layer of zinc (a few micrometers) to the tool, which slows its oxidation rate by up to 25 times.

For amateur DIY enthusiasts, hand protection can help to avoid certain injuries. However, it is more prudent to hammer slowly; the hammering speed is rarely proportional to the nail's penetration speed. With wide, ample strokes, this allows for greater precision and the use of the hammer's weight as the striking force rather than your arm. This will enable you to work more precisely, consistently, and save energy.
