Metallics MPS19 – Frequently Asked Questions
1) What thread size is the Metallics MPS19 master plug nut?
The MPS19 is a 1/4-20 nut, meaning a 1/4 inch diameter with 20 threads per inch (UNC coarse). It mates with any 1/4-20 threaded rod, bolt or stud, which is the common size for hanging electrical boxes, strut and light fixtures.
2) Will the MPS19 work with 1/4 inch all-thread rod for hanging fixtures?
Yes, as long as the rod is 1/4-20 coarse thread, which is the standard pitch on common 1/4 inch all-thread. The MPS19 is a 1/4-20 nut, so it threads straight onto that rod. It will not engage 1/4-28 fine thread rod.
3) How many pieces come in a pack of Metallics MPS19 nuts?
They ship 100 pieces to the pack. That is a bulk count intended for electrical contractors and MRO stockrooms rather than a single-fixture repair, so one pack covers a full run of fixture hangers or box supports.
4) Is the Metallics MPS19 made in the USA?
Yes, the MPS19 1/4-20 nut is USA made, which matters on public works and institutional jobs carrying domestic sourcing requirements on fasteners.
5) What part number do I order for the Metallics 1/4-20 master plug nut?
