M12 x 35.8mm NoGo™ Security Nut Cap (Closed) | Mild Steel BZP | Vital Parts - NOGO-M12-CD-BZP

Designed for larger security fixings, this M12 x 35.8mm closed NoGo™ Security Nut Cap encloses an M12 nut or bolt head within a permanent metal cover. It is produced from Mild Steel Bright Zinc Plated with a 12.4mm bolt hole, 26.5mm inside diameter and 20mm height. The closed cap is ideal when the fixing sits flush within the enclosure, helping protect substantial fastening points on barriers, gates, infrastructure and heavy-duty equipment.

What Are Closed NoGo™ Security Nut Caps?

The closed version of a NoGo™ security nut cap surrounds the fixing with a low-access metal housing. A standard nut or bolt is installed through the base, then the top insert is driven home to form a secure cover. Because the insert has no thread opening, it is best matched to fixings that do not extend above the protected area.

Common Applications

  • Heavy Gates and Barriers: Designed for larger M12 fixings used on security gates, vehicle barriers and reinforced access points.
  • Bollards and Street Installations: Covers substantial nuts or bolt heads on public-realm hardware to reduce access with standard tools.
  • Structural Security Assemblies: Suitable for robust frames, cages and protective structures that require a permanent closed fastener enclosure.
  • Utility and Transport Assets: Helps secure exposed M12 fixing points on roadside, rail and utility equipment.
