Product Description
Product Overview
The 33mm and 39mm Split Set Bolt Anchor Bolts are friction-stabilized anchors designed for full-length anchorage and active reinforcement of underground mining structures. These rock bolts provide immediate radial pressure along the entire borehole length, preventing surrounding rock slippage and maintaining structural integrity.
