Metallics JMNYN012 – Frequently Asked Questions
1) What thread size does the Metallics JMNYN012 nylon insert locknut take?
It is an M12 x 1.75 metric coarse thread hex nylon insert locknut, so it threads onto M12 x 1.75 bolts, studs, or all-thread. It will not thread onto a 1/2 inch inch-series bolt, even though the diameters are close, so check whether the rod in your job is metric before ordering.
2) How many nuts come in a jar of Metallics JMNYN012?
Each jar holds 100 M12 x 1.75 hex nylon insert locknuts. The jar is the pack type, so you are buying by the container rather than by the piece, which suits strut and channel work or a shop bin rather than a one-off repair.
3) Will a nylon insert locknut work in a high heat location like near a ballast or luminaire housing?
The locking element in the JMNYN012 is nylon, which is the limiting factor in hot locations. Where a connection runs hot, an all-metal prevailing torque lock nut or a jam nut arrangement is the better choice; keep the nylon insert type for ambient temperature electrical and mechanical fastening.
4) What part number do I order for the Metallics M12 nylon insert hex locknut?
Order Metallics JMNYN012. That is the M12 x 1.75 hex nylon insert locknut in the 100 piece jar, and it is the single model offered under that designation.
5) Can a nylon insert locknut be reused after it is backed off?
A nylon insert locknut like the JMNYN012 holds by the nylon ring deforming around the bolt thread, so the locking force drops each time it is removed and reinstalled. For a connection that matters, run a fresh nut from the jar rather than reusing one that has already been torqued down.
6) What are M12 nylon insert locknuts used for in electrical work?
They are the lock nut used on M12 threaded rod and bolted connections where vibration would otherwise loosen a plain hex nut, typical of strut and channel supports, equipment mounting, enclosure and raceway hangers. Metallics catalogs the JMNYN012 as electrical fastening hardware, supplied in jars of 100.
