If 2H Heavy Hex Nuts, in sizes 1/2-13 up to 2-8, are your typical go-to choice for most projects, consider increasing the security level for better peace of mind. By adding a couple of Bryce Security Fastener’s Key-Rex Structural Nuts to applications, you’ll protect projects from theft and tampering.
Key-Rex Structural Nuts can be installed with standard 2H Nuts. They’re certified for the pipeline industry with seven layers of patented security. Bryce Security Fastener recommends installing two Key-Rex Structural Nuts per six 2H Heavy Hex Nuts.
What’s more: no extra socket are required. The same socket is used to torque both 2H Heavy Hex Nuts and Key-Rex Structural Nuts down. The Structural Nuts also exceed pipeline torque requirements. The majority of other large, security nuts are unable to torque as high as Key-Rex, and particularly in larger sizes.
