Zinc Plated Hex Thin Nut DIN 439 Metric Steel Hexagon Nut ISO 4035 M16-M30

Description

Zinc plated hex thin nut DIN 439 is thin hexagonal jam nuts with a thickness of 0.5 x diameter. A hex jam nut is a low-profile type of hex nut, typically about half as thick as a regular hex nut. It is often used as a lock nut, where it is threaded up against a standard nut locking it in place. Also in circumstances where a standard nut is too thick for an application, a hex jam nut can be a very useful alternative. Ever Hardware provides custom made fasteners and customizable packaging.

Metric DIN 439 thin hex jam nuts are available unchamfered (Type A) and chamfered (Type B). These nuts are offered in both right-hand and left-hand thread and in steel, brass as well as stainless steel A2 and A4.

Zinc coatings prevent oxidation of the protected zinc plated hex thin nut by forming a barrier and by acting as a sacrificial anode if this barrier is damaged. Zinc oxide is a fine white dust that (in contrast to iron oxide) does not cause a breakdown of the substrate’s surface integrity as it is formed. Indeed, the zinc oxide, if undisturbed, can act as a barrier to further oxidation, in a way similar to the protection afforded to aluminum and stainless steels by their oxide layers. The majority of hardware parts are zinc-plated, rather than cadmium-plated. Galvanization, or galvanisation, (or galvanizing as it is most commonly called in that industry), is the process of applying a protective zinc coating to steel or iron, to prevent rusting. The most common method is hot-dip galvanizing, in which parts are submerged in a bath of molten zinc.
