t1 = 8 mm t2 = 100 mm h = 150 mm d = 8 mm dt = 0.7 d

Penetration of the solid shaft into the timber, tpen

Ratio of penetration of solid shaft to — = 4.42 coach screw diameter: d i.e. the ratio is greater than 4; therefore the full diameter can be used for flexure and because d > 6 mm, the coach screws will be classed as bolts for lateral strength assessment.
