Parallel-to-Grain Withdrawal Resistance of Structural Self-Tapping Screws in Canadian Timber
… investigates the withdrawal capacity of self-tapping screws (STS) inserted parallel-to-grain. An experimental study was conducted with 100 screws tested in total. The experimental program includes two main test series. First, withdrawal testing was conducted on screws with a diameter of 10 mm …

Effect of surface hardening conditions on susceptibility of fasteners to hydrogen embrittlement
… the susceptibility of case hardened steel tapping screws to internal and environmental hydrogen embrittlement is examined. Further characterization of the fastener samples through microhardness testing, microstructure review, and fracture surface examination allows the determination of …

Withdrawal and combined load capacity of threaded fastener wood joints
… wood desorption on the withdrawal resistance of tapping screws. Forty joints of two moisture conditions, green and dry at insertion and two species were tested in withdrawal. In general, maximum and proportional limit loads were not affected by desorption whereas stiffness was significantly …

Application of Ductile Yield Link in Glulam Moment Connections
… the perpendicular-to-grain direction using self-tapping screws. Failure mechanisms were analyzed, and performance characteristics related to the connection's strength, stiffness, and ductility were evaluated. Results indicated that the reinforced specimen exhibited higher strength, stiffness, and …

Reinforced Timber Laminated Veneer Lumber (LVL) Connection Loaded Perpendicular to the Grain
… the splitting resistance by inserting self-tapping screws. In the first phase, AS/NZS 4063.1-2010 tensile tests were conducted on LVL samples of two lengths using a three-point bending set-up. The load, deflection, stress, strain, and failures of the samples were measured and analyzed to …
