Bolt Products Twisted Leg bolts represent a major breakthrough in rock anchor technology.
The first chemically fastened bolts in the world to use dynamic bonding they utilise the extraction load to increase the holding power.
. Dynamic bonding describes the action under load, when the two legs are able to move independently in the glue their twisted form causes the bolt to expand, massively increasing the holding power. This is so effective that even without glue they can achieve adequate extraction resistance.
Tested by TUV Süd and numerous other independent tests have confirmed these are the stongest bolt available on the market.
