A measuring tape device may include a housing having an aperture, a reel assembly enclosed within the housing, and a blade having a first end configured to extend from the housing through the aperture and a second end configured to be wound on the reel assembly. The housing may include a first case half and a second case half. The reel assembly may be configured to alternately allow the blade to be withdrawn from the reel assembly through the aperture or received in the aperture onto the reel assembly. The first case half and the second case half may be joined together via threaded fasteners inserted into respective portions of screw bosses formed in corresponding portions of the first and second case halves. Mating features may be provided on the first and second case halves to facilitate joining the first and second case halves. At least some of the mating features may be longer than others of the mating features, or a diameter of the screw bosses is about 1.5 time to about 2.5 times larger than a diameter of the threaded fasteners.
