Mechanical Properties of Confirmat Screws Corner Joints Made of Native Wood and Wood-Based
Composites. The aim of this investigation was to design and determine the mechanical properties of confirmat
screws corner joints made of native wood and wood-based composites. The objective of the study was to
ascertain the stiffness and load carrying capacity of joints that differed in the diameter and length of confirmat
type screw, as well as in the kind of materials. The results include statistical processing of measured and
calculated data, and evaluation of the influence of selected factors on mechanical properties. The results are
applied to the calculation of the characteristic values of the properties and to the determination of the equations
for their calculation for other values of the selected factors. The characteristic values are used for the evaluation
of the joints according to the limit state method.
