Extra V2 Outdoor Screw
Traditional wood screws have a blunt thread angle of 60° (displaces material, risk of splitting) , have a thicker minor diameter thereby deforms the wood, so pre-drilling is recommended.
Chipboard screws can be used in chipboard and soft wood types without predrilling, due to its thin core diameter and sharp angle of the thread.
This sharp thread cuts into wood with lower splitting effects, while simultaneously reducing the insertion torque.This combination increases the battery life on the used power tools and has the advantage of saving production time.
The pull-out forces are also more consistent from the reduced splitting.
However, using chipboard screws in harder wood types is usually problematic because the friction and insertion torque is higher, which may result in the screws breaking.
Therefore EXPANDET has developed some special features and modifications to these screws to eliminate the limitations of the above designs and this improved range is described below.
