Product Description

Product Description

Tightening nut (for spiral bolts)----ASTM A536

It is a nut made of ductile iron, with graphite present in a spherical form and excellent ductility.

 

Due to the spherical shape of the nut, it allows the support plate to always adhere to the rock mass, which determines the spherical effect. Therefore, the board always adheres to the rock without the need to place any additives, such as concrete foundations.
