GNEE's expansion bolts are made of carbon steel, which is stronger, more durable and more corrosion-resistant than ordinary steel hooks. It ensures a long service life after proper installation. It can be used outdoors and reused.
The expansion anchor bolts are equipped with a guard, a washer and a hexagonal nut to provide a very strong anchor. As long as the threaded part is long enough, the sleeve part will be deeper and stronger.
Safe load-bearing: You will get 6 carbon steel expansion screws with a total length of 88 mm, a bolt diameter of 6 mm and a screw length of 60 mm. The expansion bolts must be installed on a relatively hard substrate. The tensile load is strongest when installed in concrete. It is not recommended for lifting where impact loads may be applied.
