Metallics 516CT – Frequently Asked Questions
1) What thread size is the Metallics 516CT tap plug?
The 516CT is a 5/16-18 tap plug, so it threads into a 5/16 inch hole cut with standard 18 threads per inch coarse thread. That is the same thread commonly used for 5/16-18 rod and bolt hardware, so a 5/16-18 tap or die will match it.
2) How many tap plugs come in a pack of Metallics 516CT?
Five pieces per pack, supplied in a pouch rather than loose or boxed. If you are plugging multiple knockouts or tapped holes across a job, order by multiples of five.
3) What material is the Metallics 516CT tap plug made of, and is it suitable for outdoor or damp locations?
It is carbon steel, uncoated as described. Carbon steel is fine for dry indoor electrical work, but in wet, damp, or corrosive locations a plated or stainless plug is the better call, since bare carbon steel will rust.
4) What is a tap plug like the Metallics 516CT actually used for?
It is a threaded plug that closes off an unused tapped hole, most often in conduit bodies, enclosures, fittings, and junction boxes. Thread it into the 5/16-18 opening to keep dust, debris, and fingers out and to keep the enclosure closed up. It is a conduit accessory, not a conduit sealing compound or a duct seal.
5) Do I order the Metallics 516CT by model number, and is there more than one size on it?
One model only: 516CT, which is the 5/16-18 carbon steel tap plug. There are no finish or size options to pick, so the model number is all you need to specify. Other thread sizes are separate part numbers.
