  • Masterful Craftsmanship: Yaysium's thread checker is crafted from 6061 aluminum and features durable, easy-to-read laser-etched markings. All pillars are made from durable SUS304 and machined to the ultimate precision, ensuring each bolt and thread complies with the Go & No Go Class 2B ANSI Standard gauge.
  • Wide-Ranging Size Detection: 16 Metric thread sizes from M3 x 0.5 to M16 x 2.0, and 20 Imperial threads from #4 - 40 Coarse to 3/4 - 16 Fine. Also included are 19 drill gauges for precise drill size identification. Provides comprehensive identification for your standard hardware.
  • Laser-Etched Double Scale: This bolt size finder features durable laser-etched 6 inch and 15cm rulers on the edge, providing quick, accurate, and user-friendly identification of various bolt, screw, nut and washer sizes.
  • Convenient Design: Our thread gauge has four non-slip support feet for stable placement on the workbench, and two hanging holes are reserved for hanging on the tool wall. Laser-precision cutting of unnecessary aluminum plates makes it lightweight and easy to carry.
  • Easy to Use: The nut and bolt thread checker simply matches your nuts and bolts to the corresponding slots to identify the size and pitch accurately. It's a tool designed for lasting reliability and convenience.
