Our metrology professionals are available to assist you with whatever you need to keep your system on the job.
    • Tool Sets
       

    • Starrett offers a selection of tools sets that combine several products in the same box. Some combine a selection of basic tools such as a 0-1” micrometer, 0-6” caliper a few other fundamental measuring tools in a single set for apprentices or beginners. Others sets are designed for the requirements of a type of application or are industry-specific.
    • Calipers, Dividers & Trammels

    • It is the most prestigious award in the automotive industry and the trophy has been seen on hundreds of ads – the unmistakable profile of a Starrett outside spring caliper.  Even with many more options available today, these tools are still the best choice for many measurement transfer, scribing and other jobs. We also offer trammel heads, divider points and attachments -- similar tools for larger applications.
    • Slide Calipers
       

    • We recognize that reliable operation and dependable accuracy are essential to your quality and manufacturing operations.

    • Data Collection Systems
       

    • Data collection is an increasingly important part of manufacturing, and one of the main drivers in the movement toward electronic measuring tools with output. At the top of the Starrett line, DataSure Wireless Data Collection is a state-of-the-art system for real-time collection and recording of measurement data. From measurement to input, it reduces steps, saves time and can totally eliminate error in the data collection process.
    • Hole & Slot Gages

    • Hole gages help determine the diameter of a hole. While their function is similar to bore gages, they are less precise, much simpler tools that require measurement of a transferred dimension. We offer several varieties of small hole gage sets as well as telescoping gages for larger holes. Our taper gages are inserted into a hole or slot, with the diameter determined by the reading on the tool’s etched scale.
    • Height Gages

    • Used from a flat surface such as a Starrett granite surface plate, height gages measure the distance from the reference surface to some feature of a part, and can do so with exceptional accuracy. Starrett offers a full range of height gages. The top-of-the-line Altissimo electronic height gage is rich in features and exceptionally accurate. Several other series’ of electronic height gages are available with a choice of range and feature sets.
    • Gage Amplifiers, Hardness & Surface Testers

    • The hardness or texture (roughness) of a surface can be important to the performance or usage of a component for a variety of reasons. Starrett has added to and updated its tester line significantly in recent years. Our bench hardness testers range from relatively simple analog models to electronic versions with broad capabilities.
    • Fixed Gage Standards

    • Fixed Gage Standards include a comprehensive choice of standard gages that quickly check dimensions on a variety of workpieces. They are very useful for in-process and final inspection. Products include pin gages, drill gages, sheet and wire gages, center gages, screw pitch gages, radius gages, ball and diameter gages, angle gages, thickness gages and feeler stock.
    • Depth Gages

    • Depth needs to be measured in many situations – sometimes by simply putting a precision rule into a hole or slot and determining a measurement by eye. For higher levels of precision, Starrett offers a choice of products varying in form, complexity, cost and accuracy. A broad selection of electronic depth gage variations is available, with or without coolant protection, and output.
    • Squares

    • Ensuring perpendicularity or squareness is at the heart of creating precision products. Starrett offers a broad range of high quality solid squares, try squares and specialty products. Our line of combination squares and accessories is especially broad and deep. Invented by our founder, the combination square was our first product and today, our brand is considered to be the best available.

    • Indicators & Gages

    • Indicators are precise gages that visually show movement, sometimes in very small increments. Among many applications, they are used on fixtures for repetitive inspection or attached to a machine for adjustment. Starrett offers a variety of each of the major classes; mechanical dial, electronic display, lever style test and back plunger. Indicator requirements are very specific and Starrett offers everything you need.
    • Precision Rules, Straight Edges & Parallels

      • Custom Gaging

      • Over 50 years, we have provided solutions to industries including energy, aerospace, automotive, food packaging, high-technology plastics, medical components, and to NASA and other government agencies.

        After we determine that no 'off-the-shelf" product is applicable, our engineers begin a dialog with the company’s staff to develop a tool for the specific task -- a process to understand the application in detail and evaluate various approaches. When a solution is found that meets the requirements to the full satisfaction of our customer. Then, through design, prototype machining and testing, the final product specification is completed.

        The resulting special product usually involves highly specialized fixturing combined with a Starrett measuring tool component -- most often an electronic or dial indicator head or a micrometer head.
