Stainless Steel Nyloc Nut DIN 985 ISO 10511 Nylon Lock A2-70 Prevailing Torque Type Hexagon Thin Nuts with Nonmetallic Insert 304 M2-M10

Description

The stainless steel nyloc nut also referred to as a nylon insert lock nut, polymer insert lock nut, or elastic stop nut, is a kind of locknut. It is a nut with a nylon collar insert that resists turning.
The plastic insert is placed at the end of the nut, and its inner diameter (ID) is slightly smaller than the major diameter of the screw. The insert deforms elastically over the threads of the screw, but threads are not cut into the nylon. The nylon insert locks the nut by friction against the screw under the applied radial compressive force. Nyloc nuts retain their locking ability up to 250 °F (121 °C). Ever Hardware provides custom made fasteners and customizable packaging.

Stainless steel nyloc nut does 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. Passivation, in physical chemistry and engineering, refers to a material becoming “passive,” that is, less affected or corroded by the environment of future use. 304 stainless steel is the most common form of stainless steel used around the world, largely due to its excellent corrosion resistance and value. It contains between 16 and 24 percent chromium and up to 35 percent nickel—as well as small amounts of carbon and manganese. The most common form of 304 stainless steel is 18-8, or 18/8, stainless steel, which contains 18 percent chromium and 8 percent nickel.
