Check Nut

Check nuts are used to make sure that another nut, once in situ, will remain in place. They are also known as lock nuts and they're used wherever there is a likelihood that the first nut might shake or vibrate loose. 
We manufacture check nuts in a wide variety of sizes using high-precision tooling which guarantees that each nut produced exactly meets the desired specification. 
Check nuts are used in all kinds of piping systems including vacuum systems, gas lines, water supply, HVAC and many more. 
Each nut come with an everlasting finish and because galvanised iron is resistant to corrosion, GI check nuts are ideal for applications involving water.
