Questions & Answers
Yes. The gauge is made of a thin piece of plastic with threaded holes. Because the plastic is so thin, there are only so many threads available. To avoid damaging the plastic threads, I believe it should be handled with care. It will, I believe, be useful in determining whether a screw has only one standard thread (such as 1/4-inch). NC20) or a standard thread (such as 1/4-inch NC20) NF28), but I don't believe it can be used to fine-tune thread cutting accuracy on a lathe. I haven't had the opportunity to use it yet.
It's about a quarter of an inch, according to my micrometer. The only drawback is that it's a polymer gauge; the good news is that this means it's tough and can flex around even the most messed-up screws and bolts. The bad news is that because it isn't stainless or titanium, it isn't very precise. It might be difficult to tell the difference between a 24 and a 36, for example. Although it is a 28 pitch thread, in my experience in the machine shop, it accurately determines the correct threading, especially when matching a broken, old, or damaged screw.
Yes, I believe so.
Yes! M1 is reached when the gauge is lowered. 4 is a fraction of the size of any computer fastener. Inch sizes as small as 0 (.) are available on the gauge. 060 inch diameter). br>br>Mike br>br>Mike br>br>Mike b

I bought this for a project that required a lot of small metric screws (an old Otari R2R tape deck), and many of them had been replaced with the incorrect size (SAE when Metric was required!). So this was a highly rated Amazon product that was VERY CHEAP in comparison to the more professional stainless steel and/or heavy duty models - Some of which cost five to eight times as much as this. When I first saw the plastic in the package, I thought to myself, "I'm going to return this. " However, after using it on a variety of screw sizes, it proved to be ineffective. a few of them are very similar in size- I said ah ha threads aren't cut correctly - to the other and one that wouldn't screw in. when, in reality, A 6 SAE screw was used where a M3 should have been by the previous owner. This metric WAS USEFUL in identifying the issue. NOW FOR THE PROBLEMS - Despite the fact that the tapped holes in the screws I tested were surprisingly accurate, the lettering on my off-the-shelf products was not. The white color gauge is well-made and crisp, with different information for each hole cut logically laid out on both sides. The main concern is DURABILITY. I can see how forcing a badly cut or damaged thread screw into this plastic device would ruin the inside threads for that hole, but the depth of the cut threads impressed me - They've been carved out of this plastic with precision and depth. If the lettering stays visible, time will tell if it will last. The threaded holes are crisp and carefully crafted (BTW - People struggle to respond to simple questions - What is the thickness of this gauge? it is 4. It's 73mm or 3/16" thick (a little thicker than I expected), stiff for plastic, and has a glossy finish. I don't think this would hold up in a machine shop, but it's also not cheap - Fine for home/hobby or even small business use as long as you remember it's plastic, so no harsh chemicals or extreme environmental conditions, must be stored in a protective case or away from anything that can scratch or damage finish, and screws tested must have clean threads and not be chewed up / damaged threads, and must not be bent - Those conditions will almost certainly destroy this gauge, though they can also harm metal gauges. I recommend lightly lubricating screw threads with non-stick cooking spray. After cleaning out all grit and grime, I used a reactive oil/grease (teflan) and hoped to get a few years out of it - Perhaps a little more. We'll see, but for $9, it's definitely worth a shot. That's an excellent deal! Chris br>br> br> br> br> br> br> br.
However, because it is made of plastic, you must be careful not to use more than one finger on it. If you use too much force when sizing things, you'll just end up re-sizing them. Thread the hole to the TPI of the object you're twisting it into. A metal version will be desired by professionals. This is excellent value for money. br>br> It's not heavy. Compared to several competing solutions, it is lighter in weight and more compact (better laid-out). A drill gauge (which will be more accurate for drill bits anyway) and one with nut gauges on the side (the bolt holes in this thread gauge will be redundant with this thread gauge, but it does not have nut sizers) are also recommended. All of them are extremely low-cost. They are low-cost and time-saving. Get a circular gauge for wire and sheet metal thickness, as well as a digital or dial caliper with a depth pin while you're at it. gauge, and you're all set.
This listing should not display a picture of an item that looks like metal because it is misleading, which is partly my fault for not reading the fine print. I wouldn't be surprised if the image was manipulated in this way. Put a plastic-looking image up there for complete transparency, and then say in the fine print that the actual item color may differ. For those who don't require metal, I'm sure this will suffice. However, regardless of how durable this is, I'd rather spend an extra ten dollars on something that will last longer. Only 3 stars due to the misleading cover.
It is a useful tool for saving money. However, because it is plastic, you must clean any dirt or dust before checking the sizes, and you must also be careful not to cross thread. br>Purchase the metal one if you have the money.
Pitch gauges are a type of pitch indicator. Size is convenient (pretty-sized). Much like the other plastic nut/bolt sizing guides, this one is well-marked and covers both SAE and metric bolts and screws, as well as the drill and tap sizes that go with them. It actually does a good job of figuring out the larger-scale issues. sized bolts/screws, but the gauge is too thin to use with confidence when working with smaller sizes (8 SAE/6mm metric and below). Don't get me wrong: it's not flimsy thin, but because of the small differences in thread pitch at these sizes, it wouldn't take much effort to run a wrong-size thread. Because it's a plastic gauge, not steel, you can't put a pitch bolt/screw through a properly sized hole. I might sharpen the correct taps by running them through the smaller holes. remove the plastic from the interior the- threads in holes; This may reduce the chance of the gauge being damaged by a thread mismatch. Overall, the drill and tap sizes are included on the gauge, which makes it a useful addition to the tool chest, despite the smaller size accuracy.
For the price, it's a great time saver. If you're concerned about cross threading holes, keep in mind that this can happen in metal as well. I know. For the past 28 years, I've worked as a machinist. If you take care not to force screws into threaded holes, this item should last for years, depending on how often you use it. If you're going to sort thousands of screws, look for a metal version if you can, but expect to pay a premium. It's exactly what I need. This is a better deal than the one I found on eBay. Prime members get free shipping and quick delivery, which I appreciate.
This is a useful tool for determining the thread pitch and size of machine screws and bolts. There are thread sizes for NC, NF, and metric in this kit. It's made of a tough plastic that should last if you take care of it. I'm sure you could strip the hole out if you tried to force the wrong size or a cross threaded screw into it. Thread sizes that are correct will screw in smoothly. When it came to nuts, bolts, and washers, I used it to sort multiple coffee cans full of random nuts and bolts into containers based on size, and I now have my own hardware store. Because there are only female threads on this, you'll need to find a bolt that's the right size to sort nuts.
