The HYTORC NUT is a three-piece fastener that will directly replace any type of helical nut. The HYTORC nut’s interlocking surfaces provide pure axial bolt tensioning without the need for an external reaction point. Furthermore, the HYTORC NUT provides accurate bolt loading because all frictional forces are integral to the controlled Clamp’s surfaces.(…)
