Product Description

By entering your model number, you can make sure that this fits.
For file hard threads and a longer, useful life, the threads are heat treated and tempered.
Hand-cutting applications are the focus of this product.
The plug style tap, with 3 to 5 threads chamfered at the tip, is the most commonly used type of tap.
NC is an abbreviation for "National Coarse Threads."
For optimal results, use a 7/8" drill bit.

Questions & Answers

Is it going to work for A? In the 1988 R-model exhaust manifold, there is a R tube to manifold thread. 30 (1- ton) 5. 7 (vin "K" with 350 cid)? New tubes are needed, so I'll have to chase down the threads. ?

It will fit; I just used it to chase the AIR tube threads on my 1988 P30 step van with a 350 carbureted engine, and it is the correct thread for what you want to do.

Is there anyone who knows what thread size will work for re-weaving? On a 2013 Chevrolet Cruze, can you tap the o2 sensor threads? Bosch sensor 16737 should be used in place of the old one. ?

If the Bosch Sensor is listed as a replacement, purchase it and use your tap and die set to inspect the threads. It's possible that the measurement system is metric. It's odd, though, that replacing the hole would necessitate retapping. This does not appear to be the case. Why not use the sensor that's right for the job? What about Pep Boys and other similar businesses?

Is this a thread tap on the right hand side?

It's a standard RH NF thread, to be sure.

What is the meaning of the letter NS?

This is the national standard.

Brittle and inexpensive
3/5

I thought buying the more expensive tap would get me better quality, but the cheaper tap from okpart worked perfectly, whereas this Century unit exploded and ruined a $250 part, despite the fact that it was only being used to clean some paint overspray out of a threaded hole.

For my purposes, it was ideal
4/5

I made use of it. For my purposes, it was ideal. I only used it to cut threads in UHMW plastic, so I can't say how well it would work in metal. I would have chosen a HSS version over a high carbon steel version if I had intended to use it to thread metal. HSS is more common in cutting bits for metals, particularly steels. It has well-defined and sharp-looking cutting edges and appears to be of very high quality.

The Worst Tap I've Ever Purchased
3/5

This spigot is completely useless. It is unable to tap aluminum in any way. It just gouges it, and if you apply enough torque to turn the tap, the one thread you worked so hard to create blows out. I took an old, worn-out 7/8 tap off the shelf that I was hoping to replace, and it cut the threads like butter. This new faucet will end up in the trash.

For a Ford Model T spark plug, this is the perfect tap
5/5

I bought it for a friend who doesn't have prime and is a huge Model T fan. This tap was used by a Model A enthusiast to clean out the threads, which were extremely old and crusty.

In this price range, the quality is superior to the competition
5/5

The taps made in the twentieth century appear to be of better quality. When I look at the country of origin, I notice that the majority of the products are made in Japan. br>br>I have several Century taps and they have never let me down.

I was surprised to find that the threads were in much better condition than I had anticipated
5/5

This tap was necessary for chasing threads on an old vise that I was restoring. The threads turned out to be in much better condition than I had anticipated. However, having any tool in your hands is preferable to not having the one you require!.
