Metallics 5811CTT – Frequently Asked Questions
1) What thread size does the Metallics 5811CTT tap cut?
The 5811CTT is a 5/8-11 tap, meaning it cuts a 5/8 inch diameter thread at 11 threads per inch, the standard UNC coarse pitch for that diameter. That matches 5/8-11 rod, anchors, and hanger hardware commonly used for overhead electrical and mechanical supports.
2) Is the 5811CTT a taper tap or a bottoming tap?
It's a taper type tap. The lead threads are ground back over several threads, so it eases into the hole and self-aligns, which is what you want for starting a thread by hand in a through hole. A taper tap will not thread to the bottom of a blind hole, so if you need full threads right to the base of a closed hole you need a bottoming (plug/finishing) tap instead.
3) Will a carbon steel tap work for tapping steel strut and channel, or do I need high speed steel?
The 5811CTT is a carbon steel tap, which suits hand tapping in mild steel, aluminum, brass, and plastics at low speed. For stainless, hardened steel, or powered tapping where heat builds, a high speed steel tap holds its edge longer.
4) What drill size do I need before using the 5/8-11 tap?
For a 5/8-11 UNC thread the standard tap drill is 17/32 inch, which gives roughly 75 percent thread engagement. Drill the hole first, then run the 5811CTT taper tap in squarely, backing it off periodically to clear chips.
5) How many taps come in the Metallics 5811CTT pack?
One tap per pack, supplied in a pouch. If you're tapping a run of hanger holes across a job, order quantity accordingly, since each pack is a single piece.
6) Can I use the 5811CTT to clean up damaged threads in an existing 5/8-11 insert or anchor?
Yes, chasing out paint, concrete slurry, or bruised threads in a 5/8-11 hole is a common use for a taper tap, and the long chamfered lead makes it easy to pick up the existing thread. Just be aware it's a cutting tap, not a thread restorer, so it will remove metal if you force it off-axis.
7) What part number do I order for the Metallics 5/8-11 taper tap?
Order Metallics 5811CTT. That's the single manufacturer part number covering the carbon steel 5/8-11 taper tap, one piece per pouch.
