Titanium can be a lower-density steel with a great deal of power. It really is silver in colour and is extremely light-weight. These traits lead for the versatility with the titanium screw.
Strain-velocity or even the PV factor is a crucial parameter that expresses check the actual load on a power screw. It can be The mixture of Get in touch with area force and sliding velocity among the screw shaft and also the nut. It's the essential design and style parameter for lead screw assemblies making use of polymer nuts.
Flat head screws are also known as slotted head screws, and so are Amongst the most commonly applied screws With regards to household repairs and hobbies.
