Middle-Eastern Market DIN7505 Countersunk Head Screw For Wood Chipboard M4.0x75MM

For very soft timbers, MDF or chipboard, you need to use chipboard screws.

Chipboard screws feature a slim shank with a very coarse thread that digs deeper and more tightly into the timber.

In other words, more timber or composite board is embedded in the thread, creating an extremely firm grip.
