Description

Self Drilling Anchor Bar R38N Rock Drilling Coupling Hot Dip Galvanized 280mm long

Features

The anchor coupler enables direct energy end-to-end transmission between the bar and bar. It can reduce loss and ensure maximum percussive energy at the drill bit. According to the minimum load specifications, the anchor coupling is guaranteed to have at least the same ultimate breaking load as the SDA dimension. The coupler is to connect two or more anchor bars for deep holes drilling and anchoring.

Advantages

  • The length of coupling could be adjustable.
  • The anchor bolt could be elongated by using couplers.
  • Unnecessary to be pulled out.
  • Drilling, grouting and anchoring can be finished at the same time.
