SZM Double-Cone Expansion Anchor Bolt

Technology characteristics
*Two expansion sleeves on the anchor rod to increase the squeezing and friction area between anchor rod and wall of hole;
*Thread on the expansion sleeves increase the friction factor of the squeezing surface;
*Spring structure of the expansion sleeves keep the bolt moving to the bottom of hole one-way;
*Thread on the expansion sleeves help reducing the weakening of anchor strength and slip;
*Two expansion sleeves structure have the function of higher succeeding expansion and break on the bolt;
*Simple shape and production technology, economic and reliable performance.
