The thread gauge set is a universal 52-piece kit designed to instantly determine the thread size of screws and nuts in both metric and imperial systems. The tool works on a simple principle - physical contact with the thread guarantees 100% accuracy without any calculations or measurement errors. This is an excellent aid for plumbers, mechanics, and repairmen who need to quickly and reliably identify thread dimensions at work.
This thread gauge set is designed for plumbers, mechanics, repairmen, and anyone who regularly works with screws and nuts. It is ideal for technicians who need to quickly determine the size of a thread, as well as being used in industrial plants, repair shops, car services, and at home for assembly or disassembly work. To determine the size, simply apply the gauge to the thread and check for a match - no additional calculations or measuring instruments are required.
Q: How does the thread gauge work, and are any additional calculations required?
The gauge works on the principle of physical contact - when applied to the thread, it immediately shows the exact size. No calculations or additional measuring tools are required, so the work is done quickly and without errors.
Q: What material are the gauges made of, and how should the set be maintained?
The gauges are made of an aluminum alloy that is resistant to wear, durable, and does not overheat during use. After use, simply put them back in the compact box with padding to keep them clean and undamaged.
Q: How many thread sizes can be determined with this set, and which systems does it cover?
The set includes 52 gauges - 24 for the metric system and 28 for the inch (SAE) system. Color coding (red/blue) helps to quickly distinguish between systems and find the required gauge.
This thread gauge set is a reliable and accurate tool for anyone who works with screws and nuts. Compact, durable, and easy to use - an excellent investment for professionals and home enthusiasts.

I don’t know how I’ve been able to live so long without one of these. Incredibly useful for finding the appropriate screw in some crappy equipment with American fasteners and strange steps.
Essential in any home workshop as long as you need to identify the diameter and pitch of screws or nuts. This set includes non-standard measurements such as 6. # -40, which is not common but is used in some older equipment.

This is a very nice set, and compact. it arrived fairly quickly, faster than all the other items in my order with other sellers. i will say this is a very high quality set, i didn’t see a single flaw, and some of these pieces are tiny, so they did a great job with this set. it’s super lightweight too. i believe the price here is very fair, i recommend this seller as well as this set. i reached out to them to see if this could be shipped quickly as i needed it, and they were expecting production to set the shipment date back a little, but it ended up shipping out a day or 2 later. i am very pleased with this purchase, excellent quality. if your considering buying one of these, i would say do it.
