Disclosed is a resin nozzle (2) adapted for securing resin set bolts into the ceilings and walls of a mine by injecting a resin sausage into a pre-drilled bolt hole. The nozzle includes a spring (16), a nozzle tip (12), and a connector member (20). The spring defines a path for the resin sausages to a pre drilled bolt hole. The nozzle tip connects to the same passage. The connector member is fastened onto rock bolting equipment to which resin sausages may be ejected therefrom.
