The Coneloc Flanged Self-Locking Hex Nut is an all metal prevailing torque type self-locking nut.
The Coneloc Flanged Nut is specially designed to reduce the bearing stress on the joint; and eliminates the need for a washer. The bearing stress is the result of tightening the nut. This can be of importance especially when tightening onto aluminium or mild steel using a high strength bolt. If the bearing stress is too high, the clamp force can decrease because of plastic deformation under the nut face. That is, the bolt can come loose without the nut and/or bolt rotating. The Coneloc Flanged Nut can prevent such plastic deformation. A washer used with a plain hex nut can achieve this with a hardened washer; however, typically washers are not hardened.
The locking action on the Coneloc Flanged Nut 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.
The all metal Coneloc Nut means that the nut can be used at elevated temperatures (up to 300 degrees), and is not affected by oil.
The property class of the Coneloc Nut is 10, so it is suitable for use with high tensile bolts of property class 10.9 and below (bolts include: 10.9, 8.8, 6.8, 5.8, 5.6, 4.8, 4.6, 3.6).
The finish on the Coneloc Nut is Electro Bright Zinc Plate (ZP), unless otherwise specified.
The Coneloc Nut meets the requirements of the BS EN ISO 2320-2008 standard (prevailing torque type steel hex nuts, mechanical and performance requirements).
The Conloc Nut can be re-used and still maintain a locking action of the nut. 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.
