Introducing the "Long Screw Nut," a locking nut that compensates for the protrusion of the anchor's trust bolt.

The long screw nut is a locking nut that compensates for the protrusion of the bolt. The installation method is simple; it only requires tightening the main body and the set screw with a torque wrench, making it easy for anyone to install.
Until now, according to JIS standards, if the protrusion of the anchor bolt did not meet the specified value, it was necessary to spend a lot of time, effort, and cost on rework.
