Blind rivet nuts: Technical Explanations
- universally useable type of nut with a high level of availability and a wide material spectrum
- used with dry and grease-free components
Small countersunk head
The countersinking of the borehole is not normally necessary when machining blind rivet nuts. If technically necessary, the countersinking is to be carried out so that the countersunk head protrudes by min. 0,1 mm after setting.
For the machining of blind rivet nuts with countersunk head, the component is only to be countersunk to a depth at which the countersunk head protrudes by min. 0,1 mm after setting.
Round shaft blind rivet nuts
- universal nut type with high availability and broad material spectrum
- use with dry and grease-free components
Blind rivet nuts with hexagonal shaft (Hexatop / Hexaform)
- shaft design with positive locking antirotation device
- preferred use with coated components
- high rotationresistance even with insufficient setting device height
- fsuitable for multiple screwing
Blind rivet nuts are distinguished by simple and rapid installation. To set the nut, it is screwed onto the threaded mandrel of the setting tool, inserted into the component borehole, and set through the tool stroke. This causes the closing bead of the nut to form. After the threaded mandrel is removed, the components can be screwed tight.
For installing the nut, various tools are available with which the procedure can be carried out carefully. Setting tools operated by muscle power or by pneumatic hydraulics which can be selected.
