Metallics 1428CTE – Frequently Asked Questions
1) What thread does the Metallics 1428CTE tap plug take?
The 1428CTE is a 1/4-28 tap plug, so it threads into a 1/4-28 UNF tapped hole. That is a fine-pitch thread, not the coarser 1/4-20, so check the pitch on the hole you are filling before ordering, the two are not interchangeable.
2) Can a 1/4-28 tap plug be used to close an unused hole in an electrical enclosure?
Yes, that is what a tap plug is for: it threads into an existing 1/4-28 tapped hole to close it off. Note it is a threaded plug, not a knockout seal, so it only works where the hole is actually tapped to 1/4-28. For a plain punched knockout you need a knockout seal or closure plug sized to the knockout diameter instead.
3) Is the Metallics 1428CTE plug steel or plastic?
Carbon steel. That makes it a better match than a plastic plug where the hole is in a metal enclosure, box, or fixture housing and the plug may see mechanical contact or heat. Carbon steel is unplated-grade base metal, so for damp or exterior locations expect it to be less corrosion-resistant than a stainless or coated plug.
4) How many tap plugs come with Metallics 1428CTE?
One plug per unit, supplied in a pouch. If you are plugging multiple knockouts or tapped holes on a job, order the quantity you need rather than assuming a multi-pack.
5) What is the Metallics part number for the 1/4-28 carbon steel tap plug?
Order it as Metallics 1428CTE. That single MPN covers the carbon steel 1/4-28 tap plug; there are no finish or size options to specify.
