Prediction of screw withdrawal resistance for plywood laminated panels and sandwich panels
Turkish Journal of ForestrySandwich panels are favorable materials for structural or non-structural components due to durability, lightness, and longevity in service life. This study aimed to predict screw withdrawal resistance of the plywood laminated medium-density fiberboard ...

Screw withdrawal capacity of full-culm P. edulis bamboo [PDF]
Construction and Building Materials, 2019 Abstract The withdrawal capacity – as determined by a modified ASTM D1761 test – of screws embedded in Phyllostachys edulis bamboo culm walls is presented, demonstrating capacities and behaviour suitable for structural load bearing applications. This study considers twelve screw type-size combinations and considers whether these are predrilled or ...

Lower Tolerance Limits for Screw Withdrawal in Wood [PDF]
Wood and Fiber Science, 2019 In this study, the lower tolerance limits (LTLs) for screw withdrawal strength in wood were investigated. For this purpose, specimens were prepared from white oak and red oak wood (22.2 x 63.5 x 305 mm), a material widely used in furniture industry. Screw withdrawal tests were performed from tansverse, radial and tangential sections of wood specimens ...

Abutment screw withdrawal after conical abutment settlement: A pilot study
Clinical Oral Implants Research, 2019 AbstractObjectiveThis study investigated the effects of abutment screw withdrawal after conical abutment settlement on the stability of the implant–abutment connection.Materials and methodsTwenty implants of a conical connection system were used. Two two‐piece abutment designs were used: cone only (n = 10; NI) and cone plus octagonal index design (n ...

Prediction of Withdrawal Resistance of Self-Tapping Screws in Softwood Structural Lumber
BioResourcesThe withdrawal resistance of self-tapping screws (STS) in Korean structural softwood in the vertical fiber direction was examined. Four representative softwood species were selected based on their specific gravity.

Wood screw design: influence of thread parameters on the withdrawal capacity [PDF]
European Journal of Wood and Wood Products, 2021 AbstractSelf-tapping wood screws are important fasteners in timber construction. A characteristic of these screws is their high axial load-bearing capacity, which also depends on their withdrawal capacity. This is used for structural design and is thus an important optimization parameter for wood screws.

Withdrawal resistance of the self-tapping screws in engineered bamboo scrimber
Construction and Building Materials, 2021 Abstract The mechanical behaviour of the engineered bamboo scrimber connected by self-tapping screws (STSs) is strongly affected by the withdrawal resistance of the STSs in the bamboo scrimber. However, existing knowledge on the withdrawal resistance of STSs in such applications is quite limited.
