Shelf Angle (Wedge) Inserts

& Shims

Simple When cast into concrete, Wedge Inserts and Askew Head Bolts provide a secure and adjustable method for fastening shelf angles and other materials to concrete structures. The anchor's wedging action reduces slippage to a minimum.

 

Shelf Angle Inserts allow vertical adjustment so veneers can be properly aligned despite construction tolerances in the building frame.

Shelf Angle (Wedge) Inserts

  • These heavy-duty malleable iron inserts have three holes for nailing to forms. Anchor loops are designed to take 3/4" reinforcing bars or anchor rods for increased anchorage in concrete.
  • Available plain or hot dip galvanized. Wedge inserts should be installed a minimum of 1-1/2" from the concrete edge.

  • Heckmann stocks steel shims in standard sizes, and custom fabricates them for special applications. Shims should be as long as the vertical legs of angles to prevent the angles from deflecting under load.
  • 1/16", 1/8", and 1/4" thick shims are available in mill galvanized (1/8" max.), plain, hot dip galvanized, and stainless steel.
