Tamper Proof Break Away Shear Nuts
Shear Nuts are conical nuts with coarse threads designed for a permanent installation where preventing tampering with the fastener assembly is important. Shear nuts get the name for the installation. They require no special tool to install, however removal will be extremely difficult, if not impossible. Each nut consists of a conical section topped by a thin, threadless standard hex nut that snaps or shears off when the torque exceeds a certain point on the nut. The finished result resembles a Tri-Groove or Trident Nut, only it does not have the grooves for installation or removal.
it can provide a permanent, one-way, high security fastening making them unsuitable for applications wherein routine maintenance would require their removal. Installed and tightened using standard tools, the hexagonal section breaks off once the required torque is reached, leaving the tightened conical section which cannot be easily loosened.
