Frequently asked questions

How can I achieve a tamperproof fixation?

In specific applications such as the installation of gates, bars, railings, urban furniture, etc. where anti-theft fixing is required, tamperproof metal anchors are used.

Rejas Ventana
Banco calle

This type of anchors have a Tx 40 hexalobular recess, which can be blocked by hitting with a zamak insert to make the fixation tamperproof, preventing its disassembly.

ESTRINVZ

Within the Index range, we have different alternatives for tamperproof fixings:

Anclaje inviolable CH INB
Anclaje inviolable CH-INB
Tornillo barraquero inviolable
Tornillo barraquero inviolable: INV
(Posibilidad de instalar en taco de nylon)

As reference:

CH-INB: tamperproof zinc-plated CH anchor
CH-INN: tamperproof black CH anchor
INVZ: tamperproof zinc-plated screw
INVN: tamperproof black screw
INVA2: tamperproof A2 stainless steel screw

All of these versions include tamperproof zamak stars with zinc plating –ESTRINVZ— or in black –ESTRINVN– in the packaging.
