REDUCED HEAD Hexagonal type (*) This document provides helpful information to the customers for choosing the rivet nuts that best satisfy the application need. For highly demanding applications on structural strength, that require in-depth analysis and validation testing, please contact Rivit. We will provide you with highly professional and qualified assistance. Pay attention to the hole and thickness range indicated in the catalogue. Each hole and thickness shall have their correct rivet nut, to prevent over-thickness, large holes, or under-thickness. Choose the suitable rivet nut shape (dome, knurled dome, hexagonal type) to withstand the desired torsional force. Provide for any possible galvanic corrosions (battery effect between base and rivet nut). Choose a dome-head or countersunk-head rivet nut, whenever possible. For a reduced head, check the hole tolerance. A smaller tightening thickness than the one indicated may result in an incorrect fastening, and thus to non-linear deformation of the deformation chamber, with the rivet nut being able to fit askew. A higher tightening thickness than indicated may result in the deformation chamber not being fully deformed and not having the specified fitting resistances. A large hole or with burrs may result in an incorrect fastening. If it is a reduced-head rivet nut, it may not hold the head, the rivet nut fitting may be askew and produce a bad deformation chamber. The rivet nut may thus be stuck on the tie rod or lose its suitable resistances. Using an askew or worn tie rod may result in a rivet nut unthreading or in an askew fitting. Excessive stroke or force may result in a rivet nut unthreading or in tie rod breaking. For a removable application with a female thread on a sheet with no access to the rear. For a removable application that requires good torque strength by creating a female thread on a sheet with no access to the rear. For a removable application that requires high torque strength by creating a female thread on a sheet with no access to the rear. For a removable application requiring with the creation of a female thread at the bottom of a sheet with no access to the rear. For a removable application requiring good torque resistance with the creation of a closed female thread at its bottom on a sheet with no access to the rear. For a removable application that requires high torque strength by creating a closed female thread at its bottom on a sheet with no access to the rear. Very soft materials that require low clamping pressure spread over a large surface area to create a thread. Very soft materials that require clamping pressure spread over a large surface area to create a thread with good strength. Applications with a removable connection that does not transmit vibrations and with good thermal and electrical insulation property. For a removable application where a male thread on a sheet with no access to the rear is to be created. For a removable application that requires good torque strength by creating a male thread on a sheet with no access to the rear. For a removable application that requires high torque strength by creating a male thread on a sheet with no access to the rear. Lightweight carpentry. General Purpose.

Maximum tolerance is 0.1 mm. 3 - The tie rod develops a tensile force to compress and deform the shank under the support. 4 - Unscrew the tie rod from the fitted rivet nut. 5 - The rivet nut is now ready, you can screw the corresponding fixing elements.
