JMIKS Fasteners supplies wedge type anchor fasteners (through bolts) for heavy-duty fixing to concrete, in mild steel and stainless steel. The anchor expands when the nut is tightened and gives a strong, reliable hold.
Through bolt for push-through installation.
The anchor is hammered into the drilled hole up to its length, minus the height of the nut.
When the nut is tightened, the tapered end of the bolt is pulled into the wedge clip and expands it.
The wedge clip grips the wall of the hole for a reliable anchorage.
Drill deeper than the minimum embedment for the anchor size, so there is room for dust and the bolt end. Always follow the installation data for the size you use.
No. Wedge anchors need solid concrete. For brick and stone, use a sleeve anchor or a rawl bolt.
They work in the same way. A single ring anchor bolt has one expansion ring, and a double ring anchor bolt has two rings for extra grip.
