Metric Tri Groove Security Nuts in Zamak 5 Zinc Alloy
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.
Zamak Zinc Alloy
Zamak is a zinc alloy family. The most common, Zamak 3, is an alloy of zinc and aluminum and the de facto choice for die casting. Zamak 5 is the same as Zamak 3 but with added copper for greater strength, hardness, and corrosive resistance at the expense of ductility. Zamak alloy has an excellent balance of physical and mechanic properties, superb castability, and long-term dimensional stability.
Tri Groove Nut Size
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 is Zamak used for?
Zamak is used in many applications such as plumbing fittings, zippers, staplers, handles, locks, die-cast toys, sheet metal tooling, automotive parts, and some firearms, to name a few.
What is meant by die casting?
Die casting is a metal casting process in which molten metal is forced under pressure into a mold cavity. Zamak 3 is the most frequently used alloy for die casting in North America.
