RS PRO Steel Lock Nut, 9/16-18in

Introducing the range of RS PRO Reversible Lock Nuts, a high-quality fastener locking solution for connecting and tightening a bolt or screw in a wide range of applications to prevent it from loosening and locking it into place, while still having the option to remove or loosen it when required. Each fastener is made from steel with a zinc coating, making them much more cost-effective than their stainless-steel counterparts, while still offering a high level of protection against surface rust and oxidisation.

Hex nuts are designed specifically for ease of use and simplicity. They are used for applications where the fastener needs to be tightened or loosened, most commonly when something needs additional security alongside the bolt to ensure a secure fixing. The main benefit of hex nuts is that they are easy to install and are available in a range of sizes to suit the application needs. Hex nuts are most commonly used in:

• Household and DIY applications


• Building and construction


• Automotive, marine and aerospace
