Hexagon Nuts including full nuts, half (Jam / Thin) nuts and Heavy Nuts
A Tie Bar Connector or Coupling Nut is essentially a very long nut, it has an internal thread from top to bottom and is used to join 2 objects with the corresponding male thread for example bolts or more likely studding.
Self locking nuts, some of the widely known designs are Aerotight, Nylock, Staytight and Philidas.
Hexagonal LHT Full Nuts are used for fastening bolts, screws, anchors, studding and other fasteners with a reversed machined thread making an anti-clockwise tightening thread (LHT).
Stainless Steel wing nuts, these nuts are used when you want to secure an object with some form of bolt but don't want to use tools.
Hexagon Domed Cap Nuts, Dome Nut or Acorn Nut, these are used on the end of a length of thread for aesthetic purposes or to protect the end of the thread from damage.
Rivet Nuts are a one piece internally threaded rivet that is anchored entirely from one side, this particular type bulge on the other side to the circular base securing it in position.
Shear nuts are also known as breakaway nuts, inviolable nuts, snap off nuts, security nuts, tamper proof nuts or permacone nuts. They are a permanent security solution ideal where maintenance is not required.
They are designed to prevent unauthorised tampering or removal of equipment and facilities. They are typically used in public areas (schools, hospitals etc) and within the fencing industry, e.g. for security perimeter fencing.
Tightened using standard spanner or socket
Breakaway nuts – how they work:
The hexagon nut section is fully tightened with a standard spanner until the pressure applied exceeds the maximum torque limit, which causes the hexagonal part of the nut to break off. This leaves a plain tamper resistant cone shape which is extremely difficult to remove as there is nothing to grip.
