  • 🔧【55-PIECE DETACHABLE THREAD CHECKER KIT】This 55-piece set includes 30 Standard and 25 Metric thread gauges, each individually nested in a custom foam insert. Unlike traditional chain-type or board-mounted checkers, these detachable gauges are ultra-lightweight and flexible—simply remove the exact gauge you need for quick thread inspection in tight, hard-to-reach spaces. Perfect for mechanics, DIYers, and workshop professionals.
  • ⚙️【PRECISION-MACHINED ALUMINUM GAUGES】Crafted from high-quality aluminum with precision machining, these thread gauges deliver reliable accuracy for identifying nut and bolt sizes. They meet standard thread specifications ensuring consistent performance and long-lasting durability. Say goodbye to guesswork and mismatched hardware.
  • 🔍【3 WAYS TO READ SIZES – CLEAR & DURABLE】Read sizes effortlessly with three intuitive options: dimensions are laser-engraved directly on each gauge for abrasion resistance, printed on the included size chart, and screen-printed on the foam insert for quick reference. Standard gauges are color-coded blue and metric gauges orange, making identification instant—even in low-light conditions.
  • 🔵【30 STANDARD THREAD SIZES – BLUE】Includes: 2-56, 4-40, 5-40, 6-32, 6-40, 8-32, 10-24, 10-32, 12-24, 3/16-24, 1/4-20, 1/4-28, 5/16-18, 5/16-24, 3/8-16, 3/8-24, 7/16-14, 7/16-20, 1/2-13, 1/2-20, 9/16-12, 9/16-18, 5/8-11, 5/8-18, 3/4-10, 3/4-16, 7/8-9, 7/8-14, 1-8, 1-12.
