CAL Large Flange, Knurled, Round Body Rivet Nut | Sherex® by PEM® Universal Fasteners
CAL – Large Flange, Knurled, Round Body Rivet Nut (Open End and Closed End)
The CAL is a large-flange, open-end, round body rivet nut from Sherex® by PEM®, designed to provide a broad bearing face on the surface of the host material. The enlarged flange spreads the clamping load over a wider area, and the knurls grip making the CAL particularly suitable for softer materials where a standard flange might pull through under load.
The open-end configuration supports through-bolt applications where full thread depth is required.
