How to install hammer-in panel undercut anchor?

The installation method of the spacing percussion panel anchor is similar to that of the anti-theftanchor. However, the distance - type panel anchor can adjust the deviation of the stone thickness itself Formula of the effective embedment depth of the distance - type panel anchor; H = plate standardthickness + upper tolerance + hex nut thickness+ 1mm gap + panel anchor installation length A

Space-type Panel Anchor Anchorage Depth Calculation
Distance - type panel anchor can adjust the deviation of the stone thickness itself.
So the depth of the distance - type panel anchor is changing.

For example : The size of panel anchor is MANKATE is 13 X 26/M8h' = 30mm + 3mm + 4mm + 1mm - 26mm = 12mmThe maximum driing depth is 33 - 12 = 21mm, and the minimum drilling depth is 27 - 12 = 15mm.MANKATE 13 x 26 M8 drilling depth range: 15-21mm.

Product Parameters

The Structural Requirement of Hammer-in Panel Undercut Anchor and Drilling
The minimum plate thickness required by the distance - typed panel anchor not less than 20mm,and the effective embedment depth in this state is 12mm. When 1 and 2, 3 and 4 are the worst material, the shear strength and tensile strength of the panel anchor.
