Metallics SLN38C – Frequently Asked Questions
1) How do slip-on locknuts differ from regular hex nuts on threaded rod?
A slip-on locknut pushes straight up the rod without spinning, then locks when load pulls down on it, so a run of hangers goes up in seconds instead of threading a hex nut down several feet of rod. A standard hex nut has to be run the whole length and is what you want where the joint gets adjusted or taken apart repeatedly. For fixed-height conduit, strut and fixture hangers on 3/8-16 rod, the slip-on saves the labor.
2) Are the Metallics SLN38C locknuts steel or stainless, and what is the plating?
Steel with zinc plating, which is the standard finish for interior dry electrical work. Zinc plated steel is not a corrosion finish for wet, exterior or corrosive locations, so for a parking deck, wash-down area or coastal exterior run, specify a stainless or hot-dip galvanized fastener instead.
3) Do I need anything else besides the SLN38C locknut to hang conduit from 3/8 rod?
The locknut is the retaining piece only. You still need the 3/8-16 threaded rod itself, whatever anchors it to the deck, and the hanger, strut or clamp the nut bears against. Nothing but the nuts is in the box.
4) How many locknuts come in a box of Metallics SLN38C?
They ship 100 to a box, which covers roughly a floor's worth of trapeze and conduit hangers at two nuts per drop. Order by the box rather than the piece.
5) Is there only one size of the Metallics SLN38C locknut?
SLN38C is a single model, the 3/8-16 size. There is no length or finish choice to make on it, so the only thing to confirm is that your rod is 3/8 inch coarse thread.
