The installation method is simply to tighten the main body and lock bolts with a torque wrench, making it easy for anyone to install!
A long screw nut is a locking nut that compensates for the protrusion of anchor bolts. The installation method is simple; you just need to tighten the nut body and the set screw with a torque wrench, making it easy for anyone to install. Have you ever experienced this? - During the renovation of soundproof walls or protective fences, the new standard base plate has insufficient protrusion. - When driving anchors, if the hole is drilled too deep, there is not enough protrusion. In such cases, using a long screw nut eliminates the need for reinstallation of the anchor and allows for easy measures against loosening!
