Abstract
A digital fastener size indicator having a housing. A fixed jaw extends from an end of the housing, while a movable jaw extends from the end of the housing adjacent to and parallel with the fixed jaw. A digital electrical length measuring circuit within the housing is connected to the movable jaw. When the movable jaw and the fixed jaw encompass a fastener and the digital electrical length measuring circuit is activated a digital readout will be presented in the housing of a single discrete number to an operator to indicate the size of the fastener.
Claims4
A digital fastener size indicator comprising:
- a housing;
- a fixed jaw extending from an end of said housing;
- a movable jaw extending from said end of said housing adjacent to and parallel with said fixed jaw;
- a digital electrical length measuring circuit within said housing connected to said movable jaw, so that when said movable jaw and said fixed jaw are placed to encompass a fastener said digital electrical measuring circuit is activated to present a digital readout in said housing of a single discrete number to indicate size of the fastener;
- a thumb slide in a transverse slot in said housing coupled to said movable jaw, so that said thumb slide can move said movable jaw towards and away from said fixed jaw;
- a cover fitted over said fixed jaw and said movable jaw is removably connected to said end of said housing;
- and
- thread measuring means on said cover for measuring the pitch of threads on a fastener.
