COMPLETE 70 PIECE THREAD GAUGE SET: This thread gauge set includes 37 standard thread sizes and 33 metric sizes for quick identification of screw, bolt, and nut threads. It is suitable for professional mechanics, technicians, workshops, and DIY users who need to check thread sizes accurately.

EXTENSIVE SIZE SELECTION: The 70 piece configuration includes a wide range of standard and metric thread sizes, including less common sizes that can be difficult to find in smaller thread checker sets. It provides a convenient selection for automotive, mechanical, repair, and general workshop applications.

INCLUDES M11 METRIC THREAD SIZES: The metric section includes M11 x 1.25 and M11 x 1.5 thread gauges along with other M11 sizes. These less common thread sizes can be useful for automotive repair and mechanical applications where accurate thread identification is required.

EASY ACCESS AND ORGANIZED STORAGE: The thread gauges come arranged in a compact black storage case with a foam rack. Each piece has its designated position, making the gauges easy to access, organize, and store between uses.

THREE WAYS TO IDENTIFY SIZES: Each gauge features laser etched size markings for direct identification. The foam storage rack also includes size labels, while color coding makes it easier to distinguish between thread types. Standard sizes are shown in blue and metric sizes are shown in red.

DURABLE ALUMINUM CONSTRUCTION: Made from aluminum, the thread gauges are designed for repeated use. The clear laser etched markings provide easy size identification and are designed to remain readable during regular handling.
