These Locator Screws will keep the 21mm Disc in place while the glue sets.
Our 21mm Sterling Silver discs fit over the top of the M2.5 nut inserted into the back of your cab.
Finish the cab either on a flat lap grinder or with silicone carbide grit to remove all bead release.
With 2 part epoxy glue suitable for glass attach the disc to the back of the cab and screw the locator screw into the hole to keep the disc in place while the glue sets.
Leave on a level area to set and when completely fixed remove the locator screw.
For more information on preparation for gluing please see my Practical ide to Cabs and Poppers Tutorial.
The price is for 5 screws.
