Title: REMOVABLY INDEXING A LOAD INDICATOR ON A FASTENER
Abstract:
A load indicator (100) is removably couplable to a fastener (102) via a male coupler (110) defined on fastener (102). Load indicator (100) includes a gauge housing (104) defining a female coupler (108). A displacement gauge (106) is disposed within housing (104) and includes a moveable probe (114) disposed within female coupler (108). A plurality of indexing projections (122) spaced about an interior of female coupler (108) are moveable to engage male coupler (110) to thereby index moveable probe (114) relative to fastener (102). A datum rod (112) is anchored at a first end within a central bore (113) defined in fastener (102) such that elongation of fastener (102) causes displacement of a second free end of datum rod (112) relative to male coupler (110). Displacement of datum rod (112) is measured by probe (114).
