Tamper Proof Nuts

Security Nuts Designed to Resist Gripping Devices

Security nuts feature a tapered diameter, making the nuts resistant to gripping devices. These nuts are designed to be extremely difficult (if not impossible) to remove without a special socket or heavy tools. Varieties include nuts that can be installed or removed with unconventional bits or ones that break away on installation requiring a grinder or extractor to remove after installing.

Security nuts are commonly used with driver-less fasteners or fasteners with an unconventional drive style for a secure assembly. If the nut is not easily accessible, the fastener assembly will be harder to be tampered with. Security nuts are commonly used in public outdoor applications, including campsites, parks, playgrounds, benches, cars, and rooftop tents. Stainless steel security nuts are perfect for this type of application since they are rust and corrosion-resistant.

Tri Groove Security Nuts

Tri Groove security nuts feature a tapered diameter, making the nuts resistant to gripping devices. They are installed using a special Tri Groove socket, which grips the indentations along the outside of the fastener to turn the nut along a thread.

Break Away Shear Nuts

Shear Nuts are conical nuts with coarse threads designed for a permanent installation where preventing tampering with the fastener assembly is important. Shear nuts get their name because of how they are installed. They require no special tool to install; however, removal will be challenging, if not impossible. Each nut consists of a conical section topped by a thin, threadless standard hex nut that snaps or shears off when the torque exceeds a certain point on the nut.

FAQs

What are tamper-resistant nuts?

Tamper resistant nuts, otherwise known as security nuts, are pieces of hardware that function as a standard fastener nut. However, they are designed to be difficult, if not impossible, to remove unless a specific driver or heavy tools are used. They're used for anti-theft applications.

How do you remove security nuts?

Security nuts are not designed to be removed. If they were, they wouldn't make very good security nuts! That being said, if they must be removed, one option would be to use a grinder and cut grooves into the sides of the security nut so that you could grip it with some pliers or vise grips. That method can work for shear nuts and tri-groove nuts but require power tools and will likely damage the material surface.

What is a shear nut?

Shear Nuts are conical nuts designed for a permanent installation where preventing tampering with the fastener assembly is important. The conical section is topped by a thin, threadless, standard hex nut that snaps or shears off when the torque exceeds a certain point on the nut. This leaves behind the conical nut, which is very difficult to grip and remove.

What are tri groove nuts?

Tri Groove nuts are a type of security nut that features a tapered diameter, making the nuts resistant to gripping devices. They are installed using a special Tri Groove socket, which grips the indentations along the outside of the fastener to turn the nut along a thread. They are designed to only be removable with their special tri-groove socket drivers.
