Product Description


  • Modified truss head features high pull-out resistance and larger area contact cause less damage for materials.
  • Patent Twister thread with high holding power is supposed to strengthen material connection and enhance construction safety.
  • Milling the wood and larger hole to lower splitting force by special U thread design.
  • The bending angel stands max. 45 degree offer flexibility and impressive deformation resistance to against temperature or environment variation.


Structural Wood Screw for Timber Application

The structural timber wood screw, characterized by its Twister thread design, demonstrates robust and reliable performance in timber connections, providing a secure and durable solution for construction applications.

 What's advantage of widely-used modified truss head for timber application?

 1.  Modified Truss Head: Highly pull-out resistance and splinter-free performance. 

 2. Carbon Steel SAE 10B21: Deformation resistance with bending angle standard minimum 45 degree.

 3. Hex-Star Recess: Preventing bit cam-out while drilling and providing the best safety-consideration.
