Yes, the Type 1 Bonded was developed with solid surface materials in mind; a single Fix has been tested rebated into Corian, using Corian glue, to an astonishing 625Kg at failure!.. and the screw attaching the Button sheared before anything else..

Even face-fixed to Corian, the Fix failed at over 200Kg in shear.

Alternatively use M4 ‘Squirrel’ inserts (www.squirrels-uk.com), or M4 Rampa BAN/BAV inserts (shopen.rampa.com) to attach Type 1 or Type 2 Fixes: (use with suitable washers when using pan head screws). The buttons ideally require M5 CSK screws for maximum strength; use M5 Rampa BAN/BAV inserts. For reduced loadings, the Buttons may also be fixed using M4 CSK screws.
