It's true, you can't sort on every ice screw in the world. *gasp* *hiss* *boo*
You'll notice there are no sortable screws from Climbing Technology, DMM, Ice Rock, Salewa, and Singing Rock. Since they're not distributed in the US we're having difficulties getting all the technical specs and official prices. [Stubai and Fixe have screws in the development phase, hopefully out next season.]
Technically these screws exist in our database but they're not listed above because they're missing the filterable specs. Instead of rendering our filters useless by showing every screw above, we're listing all these "incomplete" screws below so you can still see all the options.
