What's the difference between Undercut Anchor Bolt and Wedge Anchor ?

Undercut Anchor Bolt is one kinds of expansion bolt,it’s designed and manufactured with a high tensile strength than other normal anchor bolts due to the unique undercut hole.

There is a 2mm larger diameter at the hole bottom (we call it undercut).

So the undercut anchor bolt after the expansion is very difficult to pull it out. It's much safe for your projects.

Wedge Anchor is also one kinds of normal expansion anchor,it is straight hole,the installation is also very easy. Drilling hole with drilling tool ,then flowing dust,fix the wedge anchor and then screw the nut,finish.

The second difference is that the undercut anchor is fixing on the back of stone panel (Ceramic Tile,Fiber Cement,Porcelain tile,HPL ),so we also call it stone back anchor.Please check the drilling hole on the ceramic tile below.

Please check the photo of Jaring Undercut Anchors with Aluminum Brackets on the back of the stone panel from our Clients' Project Site.

The wedge anchor is fixing on the concrete wall or on the ground.Please check the photos below for better understanding.

Then flowing the dust from the hole with pressional tool for fixing the wedge anchor

 Last fix the through bolt with hammer to knock in and put on the square washer and then screw the nut.
