For tamper-proof connections
Do you want to protect your screw connections from unauthorized intervention? The PARRYPLUG® offers a quick and clean solution for such cases. The lock element is seated securely in the inner drive of the screw and prevents unauthorized loosening of your connection.
The simple installation and handling aid with magazine enables easy and reliable installation.
Thanks to high production accuracy the PARRYPLUG® is optimally press-fitted in the drive, and offers long-term protection.
PARRYPLUG® offers unlimited implementation possibilities, for example for marking individual screws or as an effective measure to prevent dirt accumulation.
PARRYPLUG® is made of high-performance plastic. The material allows a broad temperature range from -50 °C to +200 °C.
The locking element of the PARRYPLUG® is visually impressive. Custom colour schemes can be implemented on request.
Method and principle
Unauthorized loosening of screws on machines and equipment is a serious hazard. Therefore it is often necessary to effectively prevent undesired intervention. While conventional solutions irrevocably destroy the screw drive, PARRYPLUG® offers a completely new and innovative solution.
The locking principle of the PARRYPLUG® is based on specially designed axial ribs. These specially designed ribs guarantee a secure press-fit in the screw drive. With PARRYPLUG® the locking element locks flush or slightly recessed with the head of the screw. Even with severe vibration, the position in the drive remains ensured.
To take into account the fine tolerances of common hexagon socket drives, these locking elements are manufactured to the highest standards. Use of high-performance plastic allows a wide temperature range from -50 °C to +200 °C.
Installation and operation
Installation of the PARRYPLUG® is quite simple: Up to six plugs in the magazine enable simple installation without tools. Effortlessly insert the plug into the screw drive with a handling aid. Detach the individual plug from the handling aid by turning or tilting it. After insertion, you immediately have clean and effective protection. The installation procedure is repeated without any further preparation until all of the plugs have been installed.
