Guides a 26ga syringe needle to injection site. Consists of a stainless-steel screw 1/16" (1.6mm) shaft length. Screws with shaft lengths of 2.4mm and 3.2mm are also available. Eliminates the need for mounting screws and cranioplastic cement. It is recommended that the skin be sutured over the screw with the dummy inserted after the initial injection. The area can be reopened when additional injections are made. Remove the dummy first, then follow by re-suturing over the screw and dummy.

Screw Head Diameter: 2.5mm (.10"). Screw Shaft Diameter: 1.57mm (.62")
