Multi-Purpose 2 Pack Screw Thread Pitch Gauge Tool, Pitch Cutting Gauge Caliper Gages Measuring Tool, 51 Pcs America SAE Type + 58 Pcs Metric & America SAE Type & British Whitworth

Easy to use. There is a black tightening nut on the sides of each section. Snug tight when storing, loosen to use. I don't understand how people have problems with this, lol. Also the numbers are the exact size as the text font on my phone. They are also laser engraved. Not stamped because you'd see the impression protruding through the other side. Not printed either, obviously. There's a whitish discoloration on the reverse side of the inscriptions. This is what happens when heat is generated on zinc coated Metals. This is normal. These gauges perfectly fine and just what I expected.

Use them almost daily!!👍

Because of its small size, getting the feeler gauge leaves out are a little bit cumbersome. I'm glad that they do have a nut that you can tighten so the feeler gauge leaf will not move while using it. The markings on each leaf are small and I had to hold the gauge at a certain angle in order to be able to read the size. Also, since there are three different gauges, it would have been helpful to have which sizes are included each gauge printed on the outside of the gauge. I did this myself. Otherwise, you have to open each gauge and read one of the leaves to find out if you have the correct gauge. Since I do have both SAE and metric hardware and equipment that uses both, I do like the fact that this set includes sizes for anything I could possibly encounter. I have a feeling, though, that there will be some parts of these gauges that will go mostly unused and unnecessary.

I have American. British, old British, and Japanese cars and determining the correct threats, whether it be SAE, UNC, UNF, Metric, or Whitworth is essetial in making modifications and repairs. I have amassed awidevariety of nuts and bolts as I save and scrounge them whenever Ihave leftovers,demo work, overbuy or mistakenly buy or find them. My Little old British (LBC) Car is partially Whitworth, partly BSF and BCT, as well as NFT, NCT ad SAE. German and Japanese, though both Metric, often differ for TPCm...

Very helpful in determining thread pitch. Saves trial and error and extra trips to the hardware store. Numbers are a little hard to read but other than that great product.

I have several tap and die sets but the thread gauges included in the sets didn't include threads of a lot of more unusual fasteners this set did.

Great tool for your tool box

I can't believe the maker of this product cannot even spell metric correctly. It has METRISH stamped on the side of it. Other than that it seems ok.

Did what it is supposed to do

A must have item to measure a mystery screw or bolt ‘s thread and pitch so you can buy or make a replacement. Goes together with a tap and die kit like a ham and cheese sandwich. Good quality and accurate.

I thought that they were bigger for my hand size, they will work but it will be difficult for large hands

Haven’t found a thread pitch yet that these haven’t covered

Works but low quality
