Pozidrive Head Screws
If you have ventured into DIY
, you have surely seen that there are screws that, although they have a cross head
, have slight differences and screwdrivers do not tend to fit well.
This happens because there are two variants, the Philips and the Pozidrive
. The latter is newer and was designed to improve grip and prevent the screwdriver from slipping, wearing down and damaging the screw.
To differentiate it, you will notice that the Pozidrive has a hole in the middle of the cross
and also has four smaller lines at 45°, which share the same center.
The advantage of these Pozidrive screws is that they allow more force to be applied to the cross. This results in self-tapping a better installation in materials that are more rigid.
They are perfect, for example, for installing cup hinges with aluminum profiles,
as is the case with this Pozidrive Head Screw for hinges.
This type of screw is characterized by not having a head and being completely embedded in the wood or surface
until it reaches the piece that needs to be secured. This gives you the benefit of less exposure so it will take much longer to corrode, unlike cap screws.
However, the use of grub screws is not the same as the traditional ones, since these are used to fasten and lock parts, such as hook bolts that need these screws to fix and hold two pieces of furniture together.
Another advantage of this type for furniture is that thanks to its design, in the area where it is activated with the screwdriver, Allen key or other mechanism. It supports greater force
, since this area is surrounded by the same one that is screwed.
