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.
Inner size: M4
Length: 10 mm
Number of pieces in this set: 50
Not the right size? We sell these nuts in M4, M5, M6, M8 and M10
These nuts cannot be screwed into the wood without pre-drilling. Below is a list of drilling diameters associated with the metric values M4-M10. Please note that these are guide values, as 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.
M4: 6.1-7.0 mm
M5: 8.0-8.5 mm
M6: 8.8-9.5 mm
M8: 10.7-11.5 mm
M10: 13.0-13.5 mm
Material: zinc-aluminum alloy
