This set of threaded inserts (also called screw-in nuts) have a metric screw thread on the inside and wood thread on the outside.
After pre-drilling in wood, these can be screwed into the wood with an Allen key, after which a bolt, metal screw or threaded rod can be screwed in.
The set consists of the sizes M4 to M10 and is delivered in two boxes with compartments.

These nuts cannot be screwed into the wood without pre-drilling. The ideal drilling diameters depend on the hardness of the wood. The harder the wood, the larger the drilling diameter should be.
The drilling depth is usually: nut length plus 1 to 3 mm.
