Реферат: 5 983. Carter, J. March 20. Bolts; washers.-Metal sheets, particularly corrugated roofing sheets A, are fixed to the supporting-framework by bolts B with a rounded shoulder K, dished washer D, winged washer E, G for gripping the web F, and nuts C, H. The effect of the shoulder K and washer D is to draw the edges of the bolt-hole into the position shown, thus making the connection weatherproof. Where the framework is of wood, the bolt is replaced by a wood-screw L, Fig. 3, with a loose block or washer M with a rounded top.
