44-piece bolt and nut thread inspection tool set: A precise matching tool, including 21 bolts + 21 nut thread gauges, covering common metric and imperial specifications. It offers efficient and accurate detection. Made of high-hardness material, the box cover is equipped with a specification table, and the compartments have card slots for storage. Say goodbye to thread mismatch, saving time and preventing rework.

Its core advantage lies in its comprehensive coverage: the entire set includes 21 metric specifications + 23 imperial specifications, ranging from small sizes like M3, 6-32, etc., to large sizes like M24, 1-12, etc. It almost covers all the mainstream screw types used in daily maintenance and mechanical assembly. There is no need to temporarily search for tools due to "incomplete specifications". With just one set, most scenarios' screw matching requirements can be met.When tightening screws, do you often encounter the problem of "threads not matching the holes"? This 44-piece bolt and nut thread inspection tool kit is the "precise partner" for mechanical maintenance and industrial assembly. It can handle the inspection of thread specifications all in one set, eliminating the annoyance of mismatching.
The core feature is full coverage of specifications: it includes 21 bolt thread gauges + 21 nut thread gauges, covering common metric and imperial thread sizes. Whether it's mechanical parts, pipe interfaces, or equipment assembly, it can quickly match the corresponding thread specifications, ensuring precise and non-faulty detection.
Efficient and precise detection: The tools are clearly marked and easy to read. Just by aligning the gauge with the thread, you can quickly determine if the specifications match. It saves 80% of time compared to manual measurement; the high-hardness material is wear-resistant and durable, maintaining stable accuracy over a long period, and it can also hold up in industrial scenarios.
Portable and tidy storage: The black tool box has a partition design, and each tool has its own dedicated slot. The box cover is equipped with a specification comparison table, making it easy to find the required information when taking out the tools. There is no need to search around; the box body is lightweight and has a handle, allowing it to be used conveniently in workshops and construction sites, and the tools are less likely to be lost.
Whether you are a mechanical maintenance specialist, equipment assembly worker, or a DIY industrial enthusiast, this tool kit can transform thread detection from "guessing by experience" to "precise matching": full specifications, high precision, easy storage, significantly improving work efficiency, and avoiding rework due to mismatching.
Don't let thread mismatch delay the project schedule. Get this 44-piece bolt and nut thread inspection tool kit and make thread detection precise and efficient!
