An Analytical Model for Predicting the Axial Stress Distribution of Self-Tapping Screws Due to Axial Load and Moisture Swelling of Mass Timber Products

Buildings
Self-tapping screws are becoming increasingly popular for use in modern timber structures. The axial stress distribution of self-tapping screws due to a mechanical load has been previously studied.

Are Self-Drilling, Self-Tapping Screws Effective in Anterior Cervical Fusion Surgery? One Surgeon’s Experience with 50 Consecutive Patients

Journal of Spine Practice
Purpose Even though plate and screw designs in anterior cervical discectomy and fusion (ACDF) have evolved to improve fusion stability and enhance patient outcomes, some argue that pre-tapping remained the best option. The purpose of this study is to

Multidirectional load-carrying capacity of cross-laminated timber panel-to-panel orthogonal joint using self-tapping screws installed at an angle subjected to combined load

Journal of Wood Science
This study elaborated on the potential effects of monotonic loading on a cross-laminated timber (CLT) panel-to-panel orthogonal joint. The joint was subjected to multidirectional loading at various angles when it was connected using the self-tapping ...

PREDICTION OF WITHDRAWAL STIFFNESS OF SELF-TAPPING SCREWS

World Conference on Timber Engineering (WCTE 2023), 2023
: Self-tapping screw is a new generation of fasteners which is often inserted into the face of timber membersat an angle to develop stiff and strong connections. The withdrawal stiffness of self-tapping screws is an important property that influences the performance of the connection.
