Tri-Groove Tamper Proof T Groove Security Nuts Zamak 5 Zinc 5/16-18 QTY 10

Tapered diameter resistant to gripping devices Driven by three grooves on the outside of the nut They are also known as Trident Drive Nuts, T-Groove Nuts, and Tri Groove Nuts Commonly used on boats, docks, piers and pools 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 roof top tents. Tri Groove Security Nuts Zamak 5 Zinc Alloy Tamper Proof Nuts in this selection are made of zamak 5 zinc alloy. Tamper Resistant Design Tri Groove Nuts are circular and tapered making them extremely resistant to gripping devices. Common Applications Because of their tamper resistant design, Tri Groove Nuts are commonly used in public applications including campsites, parks, playgrounds, benches, cars and roof top tents. High quality tamper proof security nuts The added copper in Zamak 5 increases the strength, hardness, and corrosion resistance of the alloy, but reduces its ductility and dimensional accuracy compared to other Zamak Alloys.
