Boellhoff launches anti-tampering insert for hex key bolts

1 min read

To protect screw connections from unauthorised intervention, PARRYPLUG seats securely in the inner drive of the screw and prevents unauthorized loosening of your connection.

Unauthorised 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.

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.

PARRYPLUG HD is suitable for hexagon socket drives. It is available in the sizes SW3, SW4, SW5, SW6 and SW8.

PARRYPLUG TX is suitable for TX25 hexalobular socket drives.

A PARRYPLUG starter set contains plugs in the most common spanner sizes (SW3 to SW8) as well as a special removal tool. If maintenance work is required on a machine, a plug can simply be dismounted and then replaced. Thus ensuring quick recommissioning.
