All our holds are equipped with the Double Bolt System (DBS) so they can be used either with Socket Head Cap / CHC BTR (8 mm – H) bolts or Flat Socket Head / conical countersunk bolts FHC BTR (6 mm – H).
The new round head screw Button Head / BHC (6 mm – H) enables flat clamping on the XS hold models. So you can preserve your wooden structure from drilling screwholes, while still fixing technical micro holds on it.
You can also use this type of hold on concrete walls. On request, we can supply INOX screws.
