Loose retaining nuts in the foundation When retaining nuts are tightened, retaining nuts may be removed. In this case, the nut should be adjusted to the original position, the foundation around the nut should be dug out enough, and then put into the nut. The upper and lower U-shaped steel bars are welded vertically. Finally, the pit is cleaned and grouted with water. After the concrete has solidified to the design strength, the treatment method for tightening the nut deviation is roughly the same as the treatment method for the dead nut. Just remove the fastening nut. If the fastening nut is too long, you can cut a section of thread on the machine; if the fastening nut is too short, you can stretch it by hot forging; if the position is inconsistent, you can correct it by bending.
Fastening nuts can be used for various equipment fixing, steel structure embedded parts, street lamps, traffic signs, water pumps, boiler installation, heavy equipment embedded and fixed.
