M10 x 31.8mm NoGo™ Security Nut Cap (Open) | Mild Steel BZP | Vital Parts - NOGO-M10-ON-BZP

Our M10 x 31.8mm NoGo™ Security Nut Cap (Open) is intended for M10 security assemblies where a threaded section remains proud of the nut. Made from Mild Steel Bright Zinc Plated, the enclosure has a 10.4mm bolt hole, 25.3mm inside diameter and 18mm overall height. The open profile accommodates the projecting thread while shielding the nut from direct tool access, making it a practical permanent solution for exposed public and industrial fixings.

What Are Open NoGo™ Security Nut Caps?

NoGo™ open security enclosures protect a nut without requiring the protruding bolt to be shortened. The fastener passes through the enclosure base and is tightened as normal, before the open cap is driven home. Once fitted, the cap limits direct access to the nut and creates a permanent security fixing.

Common Applications

  • Gates and Security Barriers: Encloses M10 nuts on heavy gate and barrier hardware while allowing the bolt thread to pass through the cap.
  • Machine Guards: Deters access to exposed nuts on guarding and industrial frames without altering the original stud length.
  • Transport Equipment: Suitable for public-facing rail, roadside and parking installations with projecting M10 fasteners.
  • Utility Enclosures: Protects mounting nuts used on cabinets, meters and outdoor infrastructure where thread protrusion is unavoidable.
