RSP-Écrou en laiton sans tete à pression M3x5,3

Brass.
Installation by press fitting.
They are press-in expansion brass rivet nuts, designed to be used on thermosetting plastics hard and brittle.
High torque resistance.
High stress resistance allows the use of thinner studs.
The rivet nuts for plastics are designed to be installed after the moulding.
Benefits of this solutions are:
• It is possible to place rivet nuts away from the moulding zone.
• "Press open" time reduced, consequent increase of the productivity.
• Scrap rate reduced, the risk of shifting of the rivet nuts during the moulding is eliminated.
• Installation can be automated.
While choosing always consider the type of plastics and the installation process.
