Nut Type | Coneloc Nuts |
The Coneloc is an all metal prevailing torque type self-locking nut. The locking action is achieved by localised precision deformation of the thread in the cone section on top of the nut. When the nut is tightened onto the bolt, the thread is gripped on the flanks providing the locking action. This nut is of property class 10 which means that it is suitable for use with high tensile bolts of property class 10.9 and below. (That is, it can be used with property class 10.9, 8.8, 6.8, 5.8, 5.6, 4.8, 4.6 or 3.6 bolts.) The nuts meet the requirements of the BS EN ISO 2320 - 2008 standard (Prevailing torque type steel hexagon nuts - mechanical and performance requirements.) We sell as standard nuts that are electro zinc plated. As with other types of all-metal self-locking nuts, the nut can be re-used and still maintain a locking action (meeting the ISO 2320 requirements). To achieve the full locking action of the nut it is recommended that at least two bolt threads should protrude through the top of the nut. Coneloc is a trade mark of Nuts Bolts Limited.
