Certifix reduced countersunk head knurled insert nut A2 stainless M8 x 15.5

Blind rivet nuts with knurled round shank is used when an application using the hex shank is not possible. This knurling is an additional security against rotation with hard materials as opposed to unknurled blind rivets.
The tightening torque specifications are guide values depending on the material of the original component and must be checked by testing the component.

Surface-terse processing
The blind rivet can be sunk by the small countersunk shortly with the surface.
