 | Optimum
force transmission:
Drive forces are
no longer transmitted by the edges, but by the surfaces themselves.
Tool wear is therefore diminished and drive forces do not damage the
screws, even when using stainless steel screws tightened to high
torque levels. Protection against corrosion is therefore maintained.
|
|
 |
| No
axial pressure:
The cylindrical
shape of the drive end means that no axial pressure is required. The
typical "came out" effect of Phillips head patterns is
eliminated.
|
|
 |
| Less
space required:
A small screw
head saves material and takes up less room, while still being able
to accept high force levels.
|
|
 |
| Significant
potential for rationalization:
A single drive
shape can be used for a number of screws. The assortment can be
reduced and the cost of assembly tooling reduced.
|
|
 |
| Multiple
uses:
Optimal force transmission opens up the way to new possibilities for
special shapes - one tool for a number of sizes.
Assembly problems encountered with low profile or flush head screws
are a thing of the past. |
