The retainer nut includes a projection that extends outwards from the fluid end body. The fluid end includes at least one clamping assembly adapted to engage with a portion of the fluid end to prevent a rotation of the retainer nut relative to the fluid end body.

The clamp includes an annular portion that circumferentially engages with the projection of the retainer nut.
