In this study, it was determined effects of natural enviroment condition to screwholding performance of wood Material. For this purpose, it was used scotch pine (Pinus sylvestris Lipsky), oak (Quercus petreae Lipsky) and oriental beech (Fagus orientalis Lipsky). The experiment samples were impregnated by the mixture of %3 wax / %10 linseed oil/%87 white sprite and varnished by synthetic based translucent varnish. Control samples (without proceeding), impregnated and varnished samples were kept in the winter conditions (January-February-March/2009) of Ankara area waiting, in different directinons screw holdings stability were investigated. This purpose, samples prepared in laboratory experiments ASTM-D 1037 and ASTM-D 143 also conform to the principles set forth under the screws holding the static load performance (tensile) experiments has been applied. According to experimental results, screws holding the highest performancee; year rings curved surface 45 degrees (diagonal) in varnished oriental beech (Fagus orientalis Lipsky) (4776 N), the lowest performancee; in the control rings paralel to the surface scotch pine (Pinus sylvestris Lipsky) (1241 N) were obtained.
