Saima Corporation rolled out the product "Candy Nut" in June under the "TRF Anti-theft screw" series. The nut is machined into a beautiful spherical shape, underneath which the hexagonal portion can be turned with a specialized tool to fasten or remove the nut. The design of this hexagonal portion makes it impossible to be moved with an ordinary spanner or wrench. Plus, the large spherical body shields the whole structure to make itself less noticeable.
