Overview
DIN 439 is a thin hex nut with a fine thread pitch, designed to provide reliable connections in confined spaces. Its height is lower than that of standard nuts, making it suitable for installation where access or available space is limited. Different versions are available in steel, A2 stainless steel, A4 stainless steel, and brass.
The DIN 439 nut has a full internal thread that provides reliable engagement with corresponding bolts or threaded rods. It is suitable for various industries where compact dimensions and reliable threaded connections are especially important.
Applications
The DIN 439 strength class 5 zinc-plated nut has a thin hexagonal profile, making it suitable for confined spaces where standard-height nuts cannot be used. Its fine thread pitch provides precise and tight thread engagement, which is particularly important in mechanisms and structures with limited installation space.
The zinc coating provides basic corrosion protection, making the nut suitable for use in conditions of moderate humidity. It is made of strength class 5 steel, providing reliable performance under appropriate mechanical loads.
