APPLICATION

On all manner of bolting applications where movement or vibration may cause loosening typical examples would be furniture applications such as stadium seating as well as engineering machinery application.

Can be used with all types of bolts and nuts.

Stainless steel 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 or steel and corrosion resistance are required.
