3-Hole Knock-In Insert Nuts (IN18) provide the additional confidence offered by a wide collar with three 0.3mm holes. Small nails or screws can be utilised to attach the insert to the wood providing greater security.

Both of these IN18 3-Hole Knock-In Insert Nuts are treated with a Zinc Plating process which protects them from deterioration due to corrosion. Please see the availability chart below for full specifications.
