DescriptionHot Dip Galvanised Shear Nut – Tamper-Proof Security FastenerThe Hot Dip Galvanised Shear Nut is a permanent security fastener designed for applications requiring maximum tamper resistance. Once installed, the hex section shears off at a pre-set torque, leaving a smooth, conical head that resists removal. The hot dip galvanised coating provides excellent corrosion protection for outdoor and industrial environments.ApplicationsSecurity fencing, gates, and bollardsStreet lighting and public infrastructureUtility enclosures and access coversOutdoor fixtures and high-security areasFeaturesPermanent, tamper-proof design – hex shears off at rated torqueHot Dip Galvanised for corrosion resistance in harsh environmentsHigh-strength steel body suitable for structural applicationsTorque-shear calibrated for consistent installationMaterial & FinishMaterial: High-tensile carbon steelFinish: Hot Dip GalvanisedStandard: AS/NZS Security Fastening SpecificationAvailable SizesM8 | M10 | M12 | M16 | M20SpecificationsPartQFindTorque Range (Nm)SizeFinishNS05GCM08–14–20M8Hot Dip GalvanisedNS05GCM10–31–38M10Hot Dip GalvanisedNS05GCM12–52–60M12Hot Dip GalvanisedNS05GCM16–74–82M16Hot Dip GalvanisedNS05GCM20–100–113M20Hot Dip Galvanised
