Metallics 3416CTT – Frequently Asked Questions
1) What thread size does the Metallics 3416CTT tap cut?
The 3416CTT cuts a 3/4-16 thread, meaning a 3/4 inch nominal diameter at 16 threads per inch. That is the UNF (fine) pitch for 3/4 inch, not the coarse 3/4-10 UNC. If the bolt or rod you are threading for is coarse, this is the wrong tap.
2) What is a taper type tap and when should I use one instead of a plug or bottoming tap?
A taper tap has the lead chamfer ground back over several threads so it starts easily and pulls itself square, which is why it is the one you reach for first on a through hole or when starting a thread by hand. It will not cut full threads to the bottom of a blind hole; for that you follow with a plug and then a bottoming tap. The Metallics 3416CTT is the taper version in 3/4-16.
3) What size hole do I drill before running a 3/4-16 tap?
For a 3/4-16 thread the standard tap drill is 11/16 inch, which gives roughly 75 percent thread engagement in steel. Drill, deburr the mouth of the hole, and start the taper tap square. In sheet steel or strut where you are threading thin material, the same 11/16 inch hole applies.
4) Is the Metallics 3416CTT tap carbon steel or high speed steel, and does that matter for what I can thread?
It is carbon steel. Carbon steel taps cut cleanly in mild steel, aluminum, brass and plastics at hand speeds and are what most electricians carry for field work such as chasing threads in enclosures, strut and hanger rod. They lose their temper faster than HSS under heat, so keep speeds low, use cutting oil, and back off to break the chip rather than forcing through.
5) Does the Metallics 3416CTT come as a set or a single tap?
Single tap, one piece, supplied in a pouch. If you are tapping a blind hole and need the thread carried to the bottom, you will have to order the plug and bottoming taps in 3/4-16 separately; this is the taper only.
6) Can I use the 3416CTT to clean up damaged 3/4-16 threads in an existing hole?
Yes, and the taper grind is the right choice for it. The long lead lets the tap pick up the existing thread and follow it instead of cross-threading, which is what makes it useful for chasing rusted or paint-filled 3/4-16 holes in equipment and enclosures. Run it with oil and reverse frequently to clear debris.
7) What part number do I order for the Metallics 3/4-16 taper tap?
Order Metallics 3416CTT. The number reads out as the thread it cuts: 3/4-16, carbon steel, taper type.
