BOSS & STUD

Mounting-stud_iconBoss & Stud is used for a concealed mount where drilled and tapped bosses are added on the back of the plaque. Threaded studs for concealed mounting to brick, stone or cement are used or round machine screws.

Flat backed plaques do not have bosses – they have drilled and tapped holes.

HOW-TO-DO-IT

  1. Screw studs into threaded bosses (threaded holes) in back of the plaque.
  2. Using studs to locate points on mounting surface, drill holes in mounting surface slightly larger than threaded stud.
  3. If wall is solid such as cement or brick;
    i)  Discard washers and nuts. Fill holes using ‘Liquid Nails’, ‘Epoxy’ or other permanent mastic.
    ii)  Push studs into the holes and anchor plaque until mastic hardens.
  4. If you can get to the back of the wall;
    i)  Insert studs through holes and have it held in place.
    ii)  From the rear, place washers on studs and secure with nut
  5. Use liquid epoxy i ribbons across the back of the plaque to assist gluing to the rock or wall surface.
