For fastenings into hard, solid base materials, throughbolts apply wedge and friction forces to the base material, securely locking the anchor in place.
These so-called torque-controlled anchors, meaning they are tightened to a predetermined torque, are generally used for fastening medium and heavy loads, either individually or in groups.
Sormat through bolts are available in electro-galvanized, hot-dip galvanized, and A4 acid-resistant stainless steel.
