Efficient protection

against tampering

Some applications make it necessary to prevent interference by unauthorised personnel. This is
often the case with complex machinery and systems where changing the condition as delivered
®
can result in hazards. The PARRYPLUG offers a quick, neat solution for such cases.
®
PARRYPLUG (from “to parry”, meaning “to ward off”) is a locking element for internal drives
to prevent tampering with thread connections. The handling aid is used to simply insert the
®
PARRYPLUG in the internal drive of the screw. The locking element thus locks in a flush or
slightly recessed position with the head of the screw. This effectively prevents the use of a tool,
so thwarting any subsequent tampering.

®
PARRYPLUG is recommended for all areas in which the safety of man and machinery is at stake.
®
Thanks to its simple installation and unique locking effect the PARRYPLUG is also suitable for
many other applications, such as screw marking or avoiding dirt traps outdoors and in the food
processing industry.

This innovative product from Böllhoff caters for the growing demands on protection against
tampering and theft in numerous technical areas. The locking element can only be removed using
®
a special tool. The PARRYPLUG guarantees that only authorised and/or specialist staff are able
to access the relevant systems, machines and devices – so also preventing theft in an effective
manner.
