What is TURNUT made of and are there any conditions for using it?
A2) Raw material for the nut part of it is casting zinc. (The frame is made of AISI304.) The general characteristics of casting zinc include its inferiority to steel in terms of strength, the unavoidable existence of aeration during casting and its deteriorating flexibility at the extreme low temperatures of less than minus 20 degrees Celsius. Please note that it cannot be used in a corrosive environment as well as it cannot be used in any place or for the assemble of any structure where human life is put in danger. If excessive torque is applied to it during tightening, it might invite breakage of the bolt or damage to the nut. There are many applications for TURNUT such as in aluminum construction materials, doors, window frames, steel furniture and for fixing car parts, but we are recommending using INPULL NUT at places where especially high holding power is required.
