FILTH Nugget



10.9 grade zinc plated steel adapter insert for climbing holds.

Suitable for M5 and M6 screws.

For professional use only.

  • Only use for attaching climbing
    holds to birch plywood 18mm - in good condition (Meeting EN 12572-1)
  • Use 5mm minimum diameter wood screws
  • At a minimum, 3 screws are recommended for hold fixation
  • Screws are not as strong as a bolt - so this method can only be used on smaller and/or less positive holds
  • If in doubt, check with the hold manufacturer before use

Note: Screws do not give the same holding strength as bolts, we recommend a minimum of 3 screws to be used for hold fixation and only holds of a suitable shape be fixed using adapters.
