Marine Grade Tri Groove Security Nuts in 316 Stainless Steel
Conical Trident Nuts Designed to Resist Tampering
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.
Tri Groove Nuts are commonly used with driver-less fasteners, such as carriage bolts or concrete anchors 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.
Marine Grade Stainless Steel
The 316 grade of Stainless steel is suitable for highly corrosive environments, such as in saltwater or marine applications. 316 Stainless steel is equivalent to A4 stainless steel.

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.
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 likely damage the material's surface.
What does 316 mean for stainless steel?
316 is a grade of stainless steel under the 300 series of stainless steel, including 303, 304, and 305. 316 Stainless Steel is distinct from these other grades because it is highly corrosive resistant and well suited to marine applications.
Is 304 or 316 stainless better?
316 stainless steel is better in most ways over 304 stainless steel. 316 Stainless has excellent corrosion resistance, strength, and hardness and is well suited to marine applications. However, it's much more expensive than 304 and is not as formable as 304 either.
