RS PRO Lock Nut with Nylon Insert
Introducing the range of RS PRO 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. 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.
Features and Benefits:
- This range of RS PRO fasteners is ideal where a secure locking fastening is required to support medium to heavy duty applications where loosening over time can occur
- Manufactured with a zinc finish, each fastener provides good protection against surface rust and oxidisation and offers good lubricity to the threads of the fastener
- In addition to this, the zinc-plated and forged steel fasteners are much more cost effective than stainless steel and is also widely recyclable, making them a much more sustainable option
- Available in a wide range of sizes
Applications:
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
