Abstract
Screw connection is a type most commonly applied to timber structures. As important commercial tree species in
China, Masson pine and Chinese fir have the potential to prepare wood structures. In this study, the effects of the
diameter of the self-tapping screw and the guiding bores on the nail holding performance on different sections of
Masson pine and Chinese fir dimension lumbers were mainly explored. The results showed that: (1) The nail
holding strength of the tangential section was the maximum, followed by that of the radial section, and that
of the cross section was the minimum. (2) The nail holding strength of Masson pine was higher than that of
Chinese fir. (3) The nail holding strength grew with the increase in the diameter of self-tapping screws, but a large
diameter would lead to plastic cracking of the timber, thus further affecting the nail holding strength. Masson pine
and Chinese fir reached the maximum nail holding strength when the diameter of self-tapping screws was
3.5 mm. (4) Under a large diameter of screws, prefabricated guiding bores could mitigate timber cracking and
improve its nail holding strength. (5) Prefabricated guiding bores were more necessary for the screw connection
of Masson pine. The results obtained could provide a scientific basis for the screw connection design of Masson
pine and Chinese fir timber structures.
