Discover more about the Knurled Countersunk Rivet Nuts range.

Knurled Countersunk Rivet Nuts are part of Accu's extensive Rivet and Rivnut range. These components are designed to be installed into sheet metal through pre-drilled holes. The countersunk head of these components makes them suitable for use with countersunk holes, and can also allow them to indent into sheet metal, creating a more secure fixture. The threaded sleeve of these components is design to slightly deform during installation using a rivet nut tool, which makes installation permanent.

Other variants include Flat Rivet Nuts and for a reduced-head variant of this component, take a look at Accu's Knurled Reduced Head Countersunk Rivet Nut.

Stainless Steel RivNuts

Accu's Knurled Countersunk Rivet Nuts are manufactured from A2 Stainless Steel. Additional finishes such as Chemical Blackening can be applied on request.

Metric Countersunk Rivet Nuts

M3 to M12 sizes Knurled Countersunk Rivnuts are available as part of this range. Non-standard dimensions can also be manufactured on customer request.
