39mm Mining Split Set and Friction Bolt
39mm Friction Bolt and Split Set is primarily used for securing strata mesh by installing into existing 47mm friction bolts in conjunction with a smaller plate. Longer lengths are also used as primary ground support when drilling small diameter holes.
It is one of the standard Friction Bolt and Split Set widely used in worldwide project of mining, tunnel and dam as rock support material.
Diameter 40 and 42mm Friction Bolt and Split Set are also available for special required.
Different thickness is available such as 2.3mm, 2.5mm
Both galvanizing and black are available.
