  • Screw-thread gauge-wire holder
    Patent number: 5175935
    Abstract: I have invented a new and novel "holder" to hold individual threadwire gauges used to measure the thread pitch of screws and bolts. The holder takes full advantage of the properties of new materials used in the holder, including magnets, rubber and synthetic plastics. The holder will accomodate and hold in place without the use of hands on the threadwires, the wire-sets used to measure the thread pitch using the three wire method and a micrometer.
