M8 x 28.4mm NoGo™ Security Nut Cap (Closed) | Mild Steel BZP | Vital Parts - NOGO-M8-CD-BZP
This M8 x 28.4mm closed NoGo™ Security Nut Cap provides a robust way to protect an M8 nut or bolt head against unauthorised access. Made from Mild Steel Bright Zinc Plated, it combines a 8.4mm bolt hole, 20mm internal clearance and 14mm height to suit medium-duty security assemblies. The fully closed top is intended for fixings without protruding thread, creating a permanent cover that is well suited to public, commercial and industrial installations.
What Are Closed NoGo™ Security Nut Caps?
A closed NoGo™ cap converts a standard nut or bolt into a concealed security fixing without requiring a specialist drive system. The enclosure base is installed with the fastener, after which the solid insert is tapped into place to lock the assembly. This leaves no central opening, making the style suitable for flush fixings and installations where the enclosed component must be fully covered.
Common Applications
- Gates and Pedestrian Barriers: Encloses M8 nuts and bolt heads on gate hardware, hinges and barrier assemblies to deter interference.

- Vending and Gaming Equipment: Provides a permanent anti-tamper cover for external fasteners on machines installed in shared spaces.
