Jul 09, 2019· A screw propeller is a device consisting of a set of angled blades revolving around a hub to provide thrust Propellers are designed for use in different environments such as water or air, but they all use the same principl As the blades spin, they corkscrew the air or water away from the propeller, producing thrust
Helix anchors offer moderate holding strength in average soil Read about the pros and cons of helical, auger anchors here
The helical blade provides improved resistance to varus col-lapse and rotational control of the medial fracture segment compared to single screw ﬁ xation (ie, lag screws) The result is superior life-to-cut-out versus single screw ﬁ xation This is accomplished through the use of the 110 mm helical blade In addition, the use of the 110 .
