Metallics 3816CT – Frequently Asked Questions

1) What thread size is the Metallics 3816CT tap plug, and what does it thread into?
The Metallics 3816CT is a 3/8-16 tap plug, meaning a 3/8 inch diameter body with 16 threads per inch, which is the standard UNC coarse pitch for that diameter. It threads into matching 3/8-16 tapped holes in conduit fittings and electrical boxes to close them off. If the hole in your fitting is tapped 1/4-20 or 1/2-13, this plug will not engage.
2) How many tap plugs come in a pack of Metallics 3816CT?
Five plugs per pack, supplied in a pouch. For a contractor closing unused tapped holes across several fittings or boxes on one job, that covers a handful of openings per pack; order multiple packs for panel work where you are plugging a lot of knockouts and spare threaded ports.
3) Is a carbon steel tap plug OK outdoors or in a damp location?
The 3816CT is carbon steel, not stainless or zinc-plated-stated construction, so treat it as a dry or protected interior part. It seals a tapped opening against moisture and debris getting into the conduit run, but bare carbon steel in a wet or washdown location will corrode over time. For exposed exterior or corrosive environments, specify a stainless or plated plug in the same 3/8-16 thread instead.
4) Why plug an unused tapped hole in a conduit fitting instead of leaving it open?
An open tapped port or knockout in a box or fitting breaks the enclosure, letting dust, insects, and moisture into the raceway and leaving energized conductors reachable. A 3/8-16 tap plug threads in and restores the closure. Metallics lists these for panel connections, conduit termination points, and electrical box sealing in residential, commercial, and industrial work.
5) What is the Metallics part number for the 3/8-16 carbon steel tap plug?
Order it as Metallics 3816CT. The number reads directly off the thread spec: 38 for 3/8, 16 for the threads per inch, so adjacent sizes in the same family follow the same logic. Quote 3816CT when you need the 3/8-16 carbon steel version specifically.
