Experimental and Numerical Study on Shear Properties of Timber-to-timber Joint Using a Dowel Reinforced with a Self-tapping Screw [PDF]
BioResources, 2023 Herein, a beech wood dowel reinforced with a self-tapping screw (composite dowel in brief) is proposed. Composite dowels were welded into the predrilled holes by high speed rotation.

Deconstructable connector for TCC floors using self-tapping screws
Journal of Building Engineering, 2021 Abstract Timber-concrete composite (TCC) systems are effective solutions for the construction of new structural floors and the rehabilitation of the existing ones. Nevertheless, the subject of design for disassembly of TCC floors is still an area that requires further research and development.

Structural Pieces Rehabilitation with Self-Tapping Screws
International Journal of Materials Engineering, 2017 Timber is one of the oldest raw materials in construction, due to their availability worldwide, and the ease of using it. The majority of buildings in Brazil, until the Industrial Revolution, utilized this material as main input, rooting most of our cultural heritage in it.

Self-tapping screws as reinforcement for timber structures
, 2009 Modern self-tapping and continuously-threaded woodscrews enable new methods for strengthening and joining timber and glulam construction elements. As these screws have a high axial strength and an excellent continuous bond to the wood they can be used similar to steel reinforcement in concrete construction.

Danger of self-drilling self-tapping screws: case report
The Egyptian Orthopaedic Journal, 2018 Some locking plate systems make use of self-drilling and self-tapping screws. Theoretically, this technology facilitates insertion and decreases operative time. This case illustrates one possible danger of broken screws in these systems. They may carry a risk of migration within the soft tissue, which could endanger vital structures along it course of ...
