Bolt thread pitch gauge.

Thread pitch gauges are used as a reference tool in determining the pitch of a thread that is on a screw or in a tapped hole. A thread gauge also known as a screw gauge or pitch gauge is used to measure the pitch or lead of a screw thread. The thread pitch is the distance between threads expressed in millimeters measured along the length of the fastener. In addition to checking npt and bspt pipe sizes use the two included gauges for measuring thread pitch.

Coarse thread is beneficial because they are less likely to cross thread more tolerant in adverse conditions and facilitate quick assembly. This tool is not used as a precision measuring instrument rather it allows the user to determine the profile of the given thread and quickly categorize the thread by shape and pitch. In general smaller fasteners have finer thread so they have lower thread pitch. This device also saves time in that it removes the need for the user to m.

Thread pitch gauges the gorilla tool is not your ordinary thread pitch gauge. Not only will it measure thread pitch it has a bolt sizer to measure diameter and a bolt grade chart as well. Why carry around three separate tools to accurately identify your bolt or measure one aspect without determining the others. Pipe tubing and hose size identifiers.

Coarse thread series unc unrc is the most common designation for general application bolts and nuts. Thread series cover designations of diameter pitch combinations that are measured by the number of threads per inch tpi applied to a single diameter. Metric fasteners are specified with a thread pitch instead of a thread count. Find a high quality thread pitch gauge you can count on when you shop grainger.

Bolt depot purchasing manager john boucher the original boltsize it gauge is the best available in the fastener industry my customers love the fine thread coarse thread nut identifier. Wall mount thread it screw bolt and nut size identifiers. Check out this selection of screw pitch gauges that include between 14 and 51 leaves in a variety of measuring ranges in inches and in mm. For example a thread pitch of 1 5 means that the distance between one thread and the next is 1 5mm.

Check external npt thread size and taper. Use this tool to distinguish between coarse and fine thread bolts and machine screws as well as the many thread pitches used on metric bolts and machine screws.
