Rebar bolt
Manx Bolt
- Bar core diameter
- Ø 21.7 mm
- Standard length
- 0.6 - 3.0 m
- Yield strength
- Minimum: 600 MPa – 200 kN / Typical: 650 MPa – 240 kN
The Manx bolt is a solid bar rock bolt. It features a unique system that eliminates protruding threads and is ideal for low clearance applications. This reduces the risk of damage or injury. The bolt is manufactured from a specialized hot-rolled deformed bar, and includes a rib pattern for improved load transfer and effective mixing of chemical anchors during installation.
Features
-
Threadless design
The Manx Bolt eliminates protruding threads beyond the tensioning nut. This makes it ideal for low-seam height applications, and reduces the risk of injury or equipment damage.
-
Enhanced load transfer
The deformed rib pattern on the bar actively improves load transfer properties and ensures effective mixing of chemical anchors during installation.
-
Robust construction
The Manx Bolt is manufactured from a hot-rolled deformed bar. This means high tensile and shear strength, with optional corrosion protection through thermal diffused coatings.
