A plastic hand-held measuring device (dip gauge 102), can measure the depth of a hole or bore (180) or the length of a fixing (160 or 170), having particular application with composite aircraft components. A hook or tang (110), at the end of an elongate portion (108), can engage with the far end of the bore allowing the depth ascertained from a first measurement scale (112). A first formation (114f or 140) can engage with a fixing, allowing measurement of the length of the fixing from a second measurement scale (118, or 124). A plastic slide (130) can abut against a portion of the component to be measured and indicate the distance on the measurement scale that corresponds to the length of the dimension being measured. The slide (130) may be arranged to engage with successive indexed formations (notches 117) along the length of the device, so that it is inclined to remain in a position corresponding to an indexed formation. |
