Home Office approved NoGo Nut & Bolt Head Enclosures convert standard screws, bolts and nuts into ultra secure fastenings.

Used in applications as diverse as securing winch equipment to Land Rover vehicles, and prison security applications, these clever products offer the ultimate protection.




Manufactured from case hardened steel with a BZP (Bright Zinc Plated) finish, these clever NoGo enclosures are available in two types.

The "Type 1" NoGo is designed primarily for use with bolts or screws and features a solid face hammer in plug,

The "Type 2" NoGo is designed to prevent access to nuts where there is a protruding thread, which is why the hammer in plug part of the Type 2 NoGo features a hole through which the thread can protrude.

They are designed to prevent unauthorised access to the head of a bolt or screw, or to a nut.

In simple terms, the NoGo consists of a two-part cup and plug set that consists of a hardened steel Cup, with a hammer in Plug.
