Stainless Steel 316 Hex Thin Nuts DIN 439 A4 Hexagon Nut ISO 4035

Description

Stainless steel 316 hex thin nuts DIN 439 are 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.

Stainless steel 316 hex thin nuts do not readily corrode, rust or stain with water as ordinary steel does. However, it is not fully stain-proof in low-oxygen, high salinity, or poor air-circulation environments. There are different grades and surface finishes of stainless steel to suit the environment the alloy must endure. Stainless steel is used where both the properties of steel and corrosion resistance are required. Stainless steels contain sufficient chromium to form a passive film of chromium oxide, which prevents further surface corrosion by blocking oxygen diffusion to the steel surface and blocks corrosion from spreading into the metal’s internal structure. Passivation occurs only if the proportion of chromium is high enough and oxygen is present. 316 stainless steel is commonly used in many industrial applications involving processing chemicals, as well as high-saline environments such as coastal regions and outdoor areas where de-icing salts are common. Due to its non-reactive qualities, 316 stainless steel is also used in the manufacture of medical surgical instruments.
