Fastener Loads for Plywood – Screws

b) Fastener-critical joints are characterized by a shear failure of the screw shank. As shown in Figure 1, once localized crushing of the wood has occurred, resistance to fastener-head embedment into the metal causes the screw to become a shear specimen and joint behav-ior is dependent upon the shear strength of the fastener. Shear failure

Default metric fastener thread pitch. If metric thread pitch designation (e.g., " x 1.5") is omitted, it specifies coarse pitch threads. For example, M10 or M10-6g, by default, specifies M10 x 1.5. The standard metric fastener thread series for general purpose threaded components is the M thread profile and the coarse pitch thread series.
