Abstract
1,213,734. Tension indicators in fasteners. J. V. H. TRIGG. 22 May, 1969 [28 May, 1968], No. 25497/68. Heading F2H. To indicate when a predetermined tension is achieved in a fastener 1, the fastener is provided with a pin 4 secured in a central bore 2 and a dished washer 7 which assumes either of two stable positions, the washer being arranged on the pin 4 so that when the predetermined tension is applied to the fastener the washer 7 snaps from the position shown in continuous outline to the position shown by broken lines. The washer 7 may be located in a recess 9, which may accommodate a metal or plastics cap 10, and may be connected to the pin 4 by a nut (11) (Fig. 2, not shown) secured to a threaded end of the pin. The pin 4 may be soldered or rivetted in the bore 2 and the recess 9 may be sealed by an external flexible waterproof membrane and filled with a water repellant grease.
