FAQ
Q: Can the STC clamp be used for pulling steel sections horizontally?
A: Yes. Unlike gravity-activated clamps, the STC clamp uses a mechanical screw to lock. This makes it perfect for horizontal pulling and positioning of steel structures during assembly.
Q: Is it necessary to use a torque wrench for tightening?
A: While manual tightening is sufficient for most operations, we recommend ensuring the screw is fully engaged and the safety indicator (if equipped) is visible to guarantee a secure grip before lifting.
